Aims. The main objective of this study was to examine whether the Oxford Shoulder Score (OSS) demonstrated floor or ceiling effects when used to measure outcomes following shoulder arthroplasty in a large national cohort. Secondary objectives were to assess its pain and function subscales, and to identify independent predictors for patients achieving a postoperative ceiling score following shoulder arthroplasty. Methods. Secondary database analysis of the National Joint Registry (NJR), which included 48,270 patients undergoing shoulder arthroplasty, was conducted. The primary outcome measure was the OSS. Secondary outcome measures were the OSS-Function Component Subscale and OSS-Pain Component Subscale. Floor and ceiling effects were considered to be present if > 15% of patients scored either the lowest or highest possible score. Logistic regression analysis was used to identify independent predictors for scoring the highest possible OSS score postoperatively. Results. Preoperatively, 1% of patients achieved the lowest possible OSS score (0) and 0.4% of patients achieved the highest possible score (48). Postoperatively, < 1% of patients achieved the lowest score at all timepoints, but the percentage achieving the highest score at six months was 8.3%, at three years 16.9%, and at five years 17%. Male patients, those aged between 60 and 89 years, and those undergoing an anatomical total shoulder arthroplasty (ATSA) were more likely to contribute to the ceiling effect seen in the OSS questionnaire. Pain and function subscales exhibited greater ceiling effects at three years and five years when compared with the overall OSS questionnaire. Logistic regression analysis showed that sex, procedure type, and preoperative OSS score were independent predictors for scoring the highest possible OSS at years. Conclusion. Based on NJR patient-reported outcome measures data, the OSS does not exhibit a ceiling effect at six months, but does at three years and five years, in part due to outcome scores of ATSA. Preoperative OSS, age, male sex, and ATSA are independent predictors of achieving a ceiling score. Cite this article: Bone Joint J 2021;103-B(11):1717–1724

This study aims to correlate Oxford shoulder score (OSS) to EQ5D score in healthy patients presenting to a shoulder clinic with shoulder pain. OSS and EQ5D scores were collected prospectively from 101 consecutive patients presenting with shoulder pain in a shoulder clinic at one specialist centre. Patients with ASA > 2 and other significant joint arthritis were excluded from the study. Scores were collected from electronic patient records. Spearman's rho correlation of oxford shoulder scores and EQ5D scores was completed. Mean age of subjects was 51.8 (range 19.1–81.9) years, 55 of 101 subjects were men (54%). Median OSS was 26 (range 3–48) and median EQ5D score was 0.76 (range 0–0.76). Correlation for all patients was 0.624 (Sig p<0.001). This study demonstrates a strong correlation between Oxford shoulder scoring and EQ5D in a fit and well shoulder surgery clinic population. It is possible that Oxford shoulder scores may be a useful indicator of quality of life in healthy shoulder clinic patients presenting with shoulder pain

While clinically important improvements in Oxford Shoulder Scores have been defined for patients with general shoulder problems or those undergoing subacromial decompression, no threshold has been reported for classifying improvement after shoulder replacement surgery. This study aimed to establish the minimal clinically important change (MCIC) for the Oxford Shoulder Score in patients undergoing primary total shoulder replacement (TSR). Patient-reported outcomes data were sourced from the Australian Orthopaedic Association National Joint Replacement Registry Patient-Reported Outcome Measures Program. These included pre- and 6-month post-operative Oxford Shoulder Scores and a rating of patient-perceived change after surgery (5-point scale ranging from ‘much worse’ to ‘much better’). Two anchor-based methods (using patient-perceived improvement as the anchor) were used to calculate the MCIC: 1) mean change method; and 2) predictive modelling, with and without adjustment for the proportion of improved patients. The analysis included 612 patients undergoing primary TSR who provided pre- and post-operative data (58% female; mean (SD) age 70 (8) years). Most patients (93%) reported improvement after surgery. The MCIC derived from the mean change method was 6.8 points (95%CI 4.7 to 8.9). Predictive modelling produced an MCIC estimate of 11.6 points (95%CI 8.9 to 15.6), which reduced to 8.7 points (95%CI 6.0 to 12.7) after adjustment for the proportion of improved patients. For patient-reported outcome measures to provide valuable information that can support clinical care, we need to understand the magnitude of change that matters to patients. Using contemporary psychometric methods, this analysis has generated MCIC estimates for the Oxford Shoulder Score. These estimates can be used by clinicians and researchers to interpret important changes in pain and function after TSR from the patient's perspective. We conclude that an increase in Oxford Shoulder Scores of at least 9 points can be considered a meaningful improvement in shoulder-related pain and function after TSR

The use of scoring systems for surveillance of post-operative outcomes is increasing. However, the methodology of this follow-up is not universal. We set out to assess whether a postal Oxford Shoulder Score (OSS) was sufficient to identify patients who were dissatisfied and wanted further treatment. Of 88 patients who had undergone GlobalCap resurfacing in the previous 5 years, we received a completed postal OSS (Median score 33, Range 5–48) from 80 patients. Those with a score <24 (an agreed threshold for surgery pre-operatively) were brought to clinic for review. The 16 recalled patients (2 males, 14 females; age 58–85) had their OSS repeated, supervised by a clinic nurse, and had a Constant Score and an American Shoulder and Elbow Surgeons (ASES) Score performed. Satisfaction was also questioned. OSS correlated well with the Constant Score (r=0.79) and ASES (r=0.86). However, supervision increased the OSS by an average of 6 points (Mean 13.9 to 19.9) and only three of the patients proved dissatisfied with the outcome of their surgery. Used alone, an unobserved OSS may have limited value for this purpose and the use of comparative pre-operative scores or additional patient-reported outcome measures may be necessary to detect poor outcomes

Introduction: Scoring systems for assessment of shoulder function are invaluable tools in determining changes in a patient’s condition. We utilised two commonly used assessment tools in patients with conservatively treated proximal humeral fractures to establish their behaviour in this patient group.

Methods: OSS and Constant Scores were collected prospectively at 3 and 12 months post injury, for 103 consecutive patients treated conservatively for proximal humeral fractures. Comparison of the scores was undertaken by creating scattergraphs, calculating Pearson’s correlation coefficient and producing Bland and Altman plots. Sensitivity to change was calculated using paired t-tests. Linear regression analysis was finally performed to predict Constant Score from the OSS.

Results: 177 sets of scores were collected. The scores correlated well with a correlation coefficient (r) of 0.84 (p< 0.001,n=177). This relationship was equally strong at 3 (r=0.77 (p< 0.001,n=94)) and 12 months (r=0.87 (p< 0.001,n=83)) and demonstrated a clear relationship between the scoring systems. Bland and Altman plots showed good agreement between the scores. Both scores were sensitive to change over time (OSS (t(81)=6.14,p< 0.001), Constant (t(80)=−10.27,p< 0.001)). Regression analysis produced a regression equation (R2=0.70) of: Constant Score=99.3-(1.67 times OSS). This level of model fit was statistically significant (F(1,175)=412.8,(p< 0.001))

Conclusion: This study provides information about the behaviour of two frequently used functional scoring systems in patients with proximal humeral fractures. Based on our finding we feel that these scores are appropriate assessment tools in these patients. The OSS may also be considered as an alternative for assessing longer term follow up as, being solely subjective, it is easier to administer and correlates well with the Constant Score.

Aims. The aim of this study was to develop and evaluate machine-learning-based computerized adaptive tests (CATs) for the Oxford Hip Score (OHS), Oxford Knee Score (OKS), Oxford Shoulder Score (OSS), and the Oxford Elbow Score (OES) and its subscales. Methods. We developed CAT algorithms for the OHS, OKS, OSS, overall OES, and each of the OES subscales, using responses to the full-length questionnaires and a machine-learning technique called regression tree learning. The algorithms were evaluated through a series of simulation studies, in which they aimed to predict respondents’ full-length questionnaire scores from only a selection of their item responses. In each case, the total number of items used by the CAT algorithm was recorded and CAT scores were compared to full-length questionnaire scores by mean, SD, score distribution plots, Pearson’s correlation coefficient, intraclass correlation (ICC), and the Bland-Altman method. Differences between CAT scores and full-length questionnaire scores were contextualized through comparison to the instruments’ minimal clinically important difference (MCID). Results. The CAT algorithms accurately estimated 12-item questionnaire scores from between four and nine items. Scores followed a very similar distribution between CAT and full-length assessments, with the mean score difference ranging from 0.03 to 0.26 out of 48 points. Pearson’s correlation coefficient and ICC were 0.98 for each 12-item scale and 0.95 or higher for the OES subscales. In over 95% of cases, a patient’s CAT score was within five points of the full-length questionnaire score for each 12-item questionnaire. Conclusion. Oxford Hip Score, Oxford Knee Score, Oxford Shoulder Score, and Oxford Elbow Score (including separate subscale scores) CATs all markedly reduce the burden of items to be completed without sacrificing score accuracy.

Aims. Early large treatment effects can arise in small studies, which lessen as more data accumulate. This study aimed to retrospectively examine whether early treatment effects occurred for two multicentre orthopaedic randomized controlled trials (RCTs) and explore biases related to this. Methods. Included RCTs were ProFHER (PROximal Fracture of the Humerus: Evaluation by Randomisation), a two-arm study of surgery versus non-surgical treatment for proximal humerus fractures, and UK FROST (United Kingdom Frozen Shoulder Trial), a three-arm study of two surgical and one non-surgical treatment for frozen shoulder. To determine whether early treatment effects were present, the primary outcome of Oxford Shoulder Score (OSS) was compared on forest plots for: the chief investigator’s (CI) site to the remaining sites, the first five sites opened to the other sites, and patients grouped in quintiles by randomization date. Potential for bias was assessed by comparing mean age and proportion of patients with indicators of poor outcome between included and excluded/non-consenting participants. Results. No bias in treatment effect was observed overall for the CI site, or the first five sites, compared with the remaining sites in either trial. An early treatment effect on the OSS was observed for the first quintile of participants recruited to ProFHER only (clinically relevant difference of seven points). Selection bias for age was observed in the ProFHER trial only, with slightly younger patients being recruited into the study. Both trials showed some selection bias for markers of poor prognosis, although these did not appear to change over time. Conclusion. No bias in treatment effects overall were found at the CI or early sites set-up. An early treatment effect was found in one of the two trials, which was likely a chance effect as this did not continue during the study. Selection bias was observed in both RCTs, however this was minimal and did not impact on outcome. Cite this article: Bone Jt Open 2023;4(2):96–103

Aims. The Oxford Shoulder Score (OSS) is a 12-item measure commonly used for the assessment of shoulder surgeries. This study explores whether computerized adaptive testing (CAT) provides a shortened, individually tailored questionnaire while maintaining test accuracy. Methods. A total of 16,238 preoperative OSS were available in the National Joint Registry (NJR) for England, Wales, Northern Ireland, the Isle of Man, and the States of Guernsey dataset (April 2012 to April 2022). Prior to CAT, the foundational item response theory (IRT) assumptions of unidimensionality, monotonicity, and local independence were established. CAT compared sequential item selection with stopping criteria set at standard error (SE) < 0.32 and SE < 0.45 (equivalent to reliability coefficients of 0.90 and 0.80) to full-length patient-reported outcome measure (PROM) precision. Results. Confirmatory factor analysis (CFA) for unidimensionality exhibited satisfactory fit with root mean square standardized residual (RSMSR) of 0.06 (cut-off ≤ 0.08) but not with comparative fit index (CFI) of 0.85 or Tucker-Lewis index (TLI) of 0.82 (cut-off > 0.90). Monotonicity, measured by H value, yielded 0.482, signifying good monotonic trends. Local independence was generally met, with Yen’s Q3 statistic > 0.2 for most items. The median item count for completing the CAT simulation with a SE of 0.32 was 3 (IQR 3 to 12), while for a SE of 0.45 it was 2 (IQR 2 to 6). This constituted only 25% and 16%, respectively, when compared to the 12-item full-length questionnaire. Conclusion. Calibrating IRT for the OSS has resulted in the development of an efficient and shortened CAT while maintaining accuracy and reliability. Through the reduction of redundant items and implementation of a standardized measurement scale, our study highlights a promising approach to alleviate time burden and potentially enhance compliance with these widely used outcome measures.

Aims. Steroid injections are used for subacromial pain syndrome and can be administered via the anterolateral or posterior approach to the subacromial space. It is not currently known which approach is superior in terms of improving clinical symptoms and function. This is the protocol for a randomized controlled trial (RCT) to compare the clinical effectiveness of a steroid injection given via the anterolateral or the posterior approach to the subacromial space. Methods. The Subacromial Approach Injection Trial (SAInT) study is a single-centre, parallel, two-arm RCT. Participants will be allocated on a 1:1 basis to a subacromial steroid injection via either the anterolateral or the posterior approach to the subacromial space. Participants in both trial arms will then receive physiotherapy as standard of care for subacromial pain syndrome. The primary analysis will compare the change in Oxford Shoulder Score (OSS) at three months after injection. Secondary outcomes include the change in OSS at six and 12 months, as well as the Pain Numeric Rating Scale (0 = no pain, 10 = worst pain), Disabilities of Arm, Shoulder and Hand questionnaire (DASH), and 36-Item Short-Form Health Survey (SF-36) (RAND) at three months, six months, and one year after injection. Assessment of pain experienced during the injection will also be determined. A minimum of 86 patients will be recruited to obtain an 80% power to detect a minimally important difference of six points on the OSS change between the groups at three months after injection. Conclusion. The results of this trial will demonstrate if there is a difference in shoulder pain and function after a subacromial space steroid injection between the anterolateral versus posterior approach in patients with subacromial pain syndrome. This will help to guide treatment for patients with subacromial pain syndrome. Cite this article: Bone Jt Open 2024;5(9):729–735

Aims. Open reduction and plate fixation (ORPF) for displaced proximal humerus fractures can achieve reliably good long-term outcomes. However, a minority of patients have persistent pain and stiffness after surgery and may benefit from open arthrolysis, subacromial decompression, and removal of metalwork (ADROM). The long-term results of ADROM remain unknown; we aimed to assess outcomes of patients undergoing this procedure for stiffness following ORPF, and assess predictors of poor outcome. Methods. Between 1998 and 2018, 424 consecutive patients were treated with primary ORPF for proximal humerus fracture. ADROM was offered to symptomatic patients with a healed fracture at six months postoperatively. Patients were followed up retrospectively with demographic data, fracture characteristics, and complications recorded. Active range of motion (aROM), Oxford Shoulder Score (OSS), and EuroQol five-dimension three-level questionnaire (EQ-5D-3L) were recorded preoperatively and postoperatively. Results. A total of 138 patients underwent ADROM; 111 patients were available for long-term follow-up at a mean of 10.9 years (range 1 to 20). Mean age was 50.8 years (18 to 75);79 (57.2%) were female. Mean time from primary ORPF to ADROM was 11.9 months (6 to 19). Five patients developed superficial wound infection; ten developed symptomatic osteonecrosis/post-traumatic arthrosis (ON/PTA); four underwent revision arthrolysis. Median OSS improved from 17 (interquartile range (IQR) 12.0 to 22.0) preoperatively to 40.0 (IQR 31.5 to 48.0) postoperatively, and 39.0 (IQR 31.5 to 46.5) at long-term follow-up (p < 0.001). Median EQ-5D-3L improved from 0.079 (IQR -0.057 to 0.215) to 0.691 (IQR 0.441 to 0.941) postoperatively, and 0.701 (IQR 0.570 to 0.832) at long-term follow-up (p < 0.001). We found that aROM improved in all planes (p < 0.001). Among the variables assessed on multivariable analysis, a manual occupation, worsening Charlson Comorbidity Index and increasing socioeconomic deprivation were most consistently predictive of worse patient-reported outcome scores. Patients who subsequently developed ON/PTA reported significantly worse one-year and late OSS. Conclusion. ADROM in patients with persistent symptomatic stiffness following ORPF can achieve excellent short- and long-term outcomes. More deprived patients, those in a manual occupation, and those with worsening comorbidities have worse outcomes following ADROM. Cite this article: Bone Joint J 2022;104-B(1):157–167

Aims. The use and variety of stemless humeral components in anatomical total shoulder arthroplasty (TSA) have proliferated since their advent in 2004. Early outcomes are reassuring but independent mid-term results are scarce. This independent study reports a consecutive series of 143 Eclipse stemless shoulder prostheses with a minimum five-year (5 to 10) follow-up. Methods. Outcomes of 143 procedures undertaken for all indications in 131 patients were reviewed, with subset analysis of those for osteoarthritis (OA) (n = 99). The primary outcome was the Oxford Shoulder Score (OSS) at a minimum of five years. Secondary outcomes were ranges of motion and radiological analysis of humeral radiolucency, rotator cuff failure, and glenoid loosening. Results. Mean OSS at mean follow-up of 6.67 years (5.0 to 10.74) was 40.12 (9 to 48), with no statistically significant difference between those implanted for a non-OA indication and those for OA (p = 0.056) or time-dependent deterioration between two years and five years (p = 0.206). Ranges of motion significantly improved compared with preoperative findings and were maintained between two and five years with a mean external rotation of 38° (SD 18.1, 0 to 100) and forward elevation of 152° (SD 29.9, 90 to 180). Of those components with radiographs suitable for analysis (n = 83), 23 (28%) were found to have a least one humeral radiolucent line, which were predominantly incomplete, less than 2 mm, and in a single anatomical zone. No humeral components were loose. A radiolucent line was present around 22 (15%) of glenoid components, and 15 (10%) of components had failed. Rotator cuff failure was found in 21 (15%) components. The mean time to either glenoid or rotator cuff failure was greater than three years following implantation. Survivorship was 96.4% (95% CI 91.6 to 98.5, number at risk 128) at five years, and 94.3% (95% CI 88.2 to 97.3, number at risk 76) at seven years, both of which compare favourably with best results taken from available registries. Conclusion. Functional and radiological outcomes of the Eclipse stemless TSA are excellent, with no loose humeral components at minimum five-year follow-up. The presence of radiolucent lines is of interest and requires long-term observation but does not impact on the clinical results. Of the eight revisions required, this was predominantly for glenoid and rotator cuff failure. Cite this article: Bone Joint J 2022;104-B(1):83–90

Aims

The aim of this study was to explore whether time to surgery affects functional outcome in displaced proximal humeral fractures

Aims. Frozen shoulder is a common, painful condition that results in impairment of function. Corticosteroid injections are commonly used for frozen shoulder and can be given as glenohumeral joint (GHJ) injection or suprascapular nerve block (SSNB). Both injection types have been shown to significantly improve shoulder pain and range of motion. It is not currently known which is superior in terms of relieving patients’ symptoms. This is the protocol for a randomized clinical trial to investigate the clinical effectiveness of corticosteroid injection given as either a GHJ injection or SSNB. Methods. The Therapeutic Injections For Frozen Shoulder (TIFFS) study is a single centre, parallel, two-arm, randomized clinical trial. Participants will be allocated on a 1:1 basis to either a GHJ corticosteroid injection or SSNB. Participants in both trial arms will then receive physiotherapy as normal for frozen shoulder. The primary analysis will compare the Oxford Shoulder Score (OSS) at three months after injection. Secondary outcomes include OSS at six and 12 months, range of shoulder movement at three months, and Numeric Pain Rating Scale, abbreviated Disabilities of Arm, Shoulder and Hand score, and EuroQol five-level five-dimension health index at three months, six months, and one year after injection. A minimum of 40 patients will be recruited to obtain 80% power to detect a minimally important difference of ten points on the OSS between the groups at three months after injection. The study is registered under ClinicalTrials.gov with the identifier NCT04965376. Conclusion. The results of this trial will demonstrate if there is a difference in shoulder pain and function after GHJ injection or SSNB in patients with frozen shoulder. This will help provide effective treatment to patients with frozen shoulder. Cite this article: Bone Jt Open 2023;4(3):205–209

Abstract. Aim. The aim of this study was to present the results of treatment of displaced lateral clavicle fractures by an arthroscopically inserted tightrope device (‘Dogbone’, Arthrex). Methods. We performed a retrospective series of our patients treated with this technique between 2015 and 2019. Patients were identified using the ‘CRS Millennium’ software package and operation notes/clinic letters were analysed. We performed an Oxford Shoulder Score (OSS) on all the patients at final follow-up. Our electronic ‘PACS’ system was used to evaluate union in the post-operative radiographs. Results. We treated 26 patients with displaced lateral clavicle fractures between 2015 and 2019. There were 4 patients who were treated with a ‘dogbone’ and supplementary plate fixation and the remaining 22 were treated with a ‘dogbone’ alone. Radiological union was seen in 22 (84%) patients. The mean Oxford Shoulder Score (OSS) was 46. Apart from one patient who required removal of the superior endobutton and knot under local anaesthetic there was no other secondary surgery. There were no cases of infection, nerve injury or frozen shoulder. Conclusions. Arthroscopic ‘dogbone’ treatment of lateral clavicle fractures is a safe, cosmetically friendly technique with promising high rates of fracture union and return to normal function. We recommend its use over the more conventional treatment of a hook plate

Aims. Reverse total shoulder arthroplasty (rTSA) can be used in complex cases when the glenoid requires reconstruction. In this study, a baseplate with composite bone autograft and a central trabecular titanium peg was implanted, and its migration was assessed for two years postoperatively using radiostereometric analysis (RSA). Methods. A total of 14 patients who underwent a rTSA with an autograft consented to participate. Of these, 11 had a primary rTSA using humeral head autograft and three had a revision rTSA with autograft harvested from the iliac crest. The mean age of the patients was 66 years (39 to 81). Tantalum beads were implanted in the scapula around the glenoid. RSA imaging (stereographic radiographs) was undertaken immediately postoperatively and at three, six, 12, and 24 months. Analysis was completed using model-based RSA software. Outcomes were collected preoperatively and at two years postoperatively, including the Oxford Shoulder Score, the American Shoulder and Elbow Score, and a visual analogue score for pain. A Constant score was also obtained for the assessment of strength and range of motion. Results. RSA analysis showed a small increase in all translation and rotational values up to six months postoperatively, consistent with settling of the implant. The mean values plateaued by 12 months, with no evidence of further migration. In four patients, there was significant variation outside the mean, which corresponded to postoperative complications. There was a significant improvement in the clinical and patient-reported outcomes from the preoperative values to those at two years postoperatively (p < 0.001). Conclusion. These findings show, using RSA, that a glenoid baseplate composite of a trabecular titanium peg with autograft stabilizes within the glenoid about 12 months after surgery, and reinforce findings from a previous study of this implant/graft with CT scans at two years postoperatively, indicating that this type of structural composite results in sound early fixation.

We assessed the predictive value of the macroscopic and detailed microscopic appearance of the coracoacromial ligament, subacromial bursa and rotator-cuff tendon in 20 patients undergoing subacromial decompression for impingement in the absence of full-thickness tears of the rotator cuff. Histologically, all specimens had features of degenerative change and oedema in the extracellular matrix. Inflammatory cells were seen, but there was no evidence of chronic inflammation. However, the outcome was not related to cell counts. At three months the mean Oxford shoulder score had improved from 29.2 (20 to 40) to 39.4 (28 to 48) (p < 0.0001) and at six months to 45.5 (36 to 48) (p < 0.0001). At six months, although all patients had improved, the seven patients with a hooked acromion had done so to a less extent than those with a flat or curved acromion judged by their mean Oxford shoulder scores of 43.5 and 46.5 respectively (p = 0.046). All five patients with partial-thickness tears were within this group and demonstrated less improvement than the patients with no tear (mean Oxford shoulder scores 43.2 and 46.4, respectively, p = 0.04). These findings imply that in the presence of a partial-thickness tear subacromial decompression may require additional specific treatment to the rotator cuff if the outcome is to be improved further

Aims. Stemless humeral implants have been developed to overcome stem-related complications in total shoulder arthroplasty (TSA). However, stemless implant designs may hypothetically result in less stable initial fixation, potentially affecting long-term survival. The aim of this study is to investigate early fixation and migration patterns of the stemless humeral component of the Simpliciti Shoulder System and to evaluate clinical outcomes. Methods. In this prospective cohort study, radiostereometric analysis (RSA) radiographs were obtained in 24 patients at one day, six weeks, six months, one year, and two years postoperatively. Migration was calculated using model-based RSA. Clinical outcomes were evaluated using the visual analogue scale (VAS), the Oxford Shoulder Score (OSS), the Constant-Murley Score (CMS), and the Disabilities of the Arm, Shoulder and Hand (DASH) score. Results. At two years, median translation along the x-, y-, and z-axis was -0.12 mm (interquartile range (IQR) -0.18 to 0.02), -0.17 mm (IQR -0.27 to -0.09), and 0.09 mm (IQR 0.02 to 0.31). Median rotation around the x-, y-, and z-axis was 0.12° (IQR -0.50 to 0.57), -0.98° (IQR -1.83 to 1.23), and 0.09° (IQR -0.76 to 0.30). Overall, 20 prostheses stabilized within 12 months postoperatively. Four prostheses showed continuous migration between 12 and 24 months. At two-year follow-up, with the exception of one revised prosthesis, all clinical scores improved significantly (median VAS difference at rest: -3.0 (IQR -1.5 to -6.0); OSS 22.0 (IQR 15.0 to 25.0); CMS 29.5 (IQR 15.0 to 35.75); and DASH -30.0 (IQR -20.6 to -41.67) (all p < 0.001)) with the exception of one revised prosthesis. Conclusion. In conclusion, we found that 20 out of 24 implants stabilized within 12 months postoperatively. The significance of continuous migration in four implants is unclear and future research on the predictive value of early migration for future loosening in TSA is required. Clinical results revealed a clinically relevant improvement. Cite this article: Bone Joint J 2022;104-B(1):76–82

Aims. Long-term outcomes following the use of human dermal allografts in the treatment of symptomatic irreparable rotator cuff tears are not known. The aim of this study was to evaluate these outcomes, and to investigate whether this would be a good form of treatment in young patients in whom a reverse shoulder arthroplasty should ideally be avoided. Methods. This prospective study included 47 shoulders in 45 patients who underwent an open reconstruction of the rotator cuff using an interposition GraftJacket allograft to bridge irreparable cuff tears, between January 2007 and November 2011. The Oxford Shoulder Score (OSS), pain score, and range of motion (ROM) were recorded preoperatively and at one year and a mean of 9.1 years (7.0 to 12.5) postoperatively. Results. There was significant improvement in the mean OSS from 24.7 (SD 5.4) preoperatively to 42.0 (SD 6.3) at one year, and this improvement was maintained at 9.1 years (p < 0.001), with a score of 42.8 (SD 6.8). Similar significant improvements in the pain score were seen and maintained at the final follow-up from 6.1 (SD 1.6) to 2.1 (SD 2.3) (p < 0.001). There were also significant improvements in the ROM of the shoulder, and patient satisfaction was high. Conclusion. The use of an interposition human dermal allograft in patients with an irreparable rotator cuff tear leads to good outcomes that are maintained at a mean of nine years postoperatively.

Aims. Reverse total shoulder arthroplasty (RTSA) using trabecular metal (TM)-backed glenoid implants has been introduced with the aim to increase implant survival. Only short-term reports on the outcomes of TM-RTSA have been published to date. We aim to present the seven-year survival of TM-backed glenoid implants along with minimum five-year clinical and radiological outcomes. Methods. All consecutive elective RTSAs performed at a single centre between November 2008 and October 2014 were reviewed. Patients who had primary TM-RTSA for rotator cuff arthropathy and osteoarthritis with deficient cuff were included. A total of 190 shoulders in 168 patients (41 male, 127 female) were identified for inclusion at a mean of 7.27 years (SD 1.4) from surgery. The primary outcome was survival of the implant with all-cause revision and aseptic glenoid loosening as endpoints. Secondary outcomes were clinical, radiological, and patient-related outcomes with a five-year minimum follow-up. Results. The implant was revised in ten shoulders (5.2%) with a median time to revision of 21.2 months (interquartile range (IQR) 9.9 to 41.8). The Kaplan-Meier survivorship estimate at seven years was 95.9% (95% confidence interval (CI) 91.7 to 98; 35 RTSAs at risk) for aseptic mechanical failure of the glenoid and 94.8% (95% CI 77.5 to 96.3; 35 RTSAs at risk) for all-cause revision. Minimum five-year clinical and radiological outcomes were available for 103 and 98 RTSAs respectively with a median follow-up time of six years (IQR 5.2 to 7.0). Median postoperative Oxford Shoulder Score was 38 (IQR 31 to 45); median Constant and Murley score was 60 (IQR 47.5 to 70); median forward flexion 115° (IQR 100° to 125°); median abduction 95° (IQR 80° to 120°); and external rotation 25° (IQR 15° to 40°) Scapular notching was seen in 62 RTSAs (63.2%). Conclusion. We present the largest and longest-term series of TM-backed glenoid implants demonstrating 94.8% all-cause survivorship at seven years. Specifically pertaining to glenoid loosening, survival of the implant increased to 95.9%. In addition, we report satisfactory minimum five-year clinical and radiological outcomes.

Aims. The Mathys Affinis Short is the most frequently used stemless total shoulder prosthesis in the UK. The purpose of this prospective cohort study is to report the survivorship, clinical, and radiological outcomes of the first independent series of the Affinis Short prosthesis. Methods. From January 2011 to January 2019, a total of 141 Affinis Short prostheses were implanted in 127 patients by a single surgeon. Mean age at time of surgery was 68 (44 to 89). Minimum one year and maximum eight year follow-up (mean 3.7 years) was analyzed using the Oxford Shoulder Score (OSS) at latest follow-up. Kaplan-Meier survivorship analysis was performed with implant revision as the endpoint. Most recently performed radiographs were reviewed for component radiolucent lines (RLLs) and proximal humeral migration. Results. Five shoulders underwent revision surgery (3.5%); three for rotator cuff failure, one for infection, and one for component malposition. Survivorship of the implant was 95.4% (95% confidence interval 90.1% to 97.9%) at five and nine years. Mean OSS improved significantly compared to preoperative values from 19.0 (1 to 35) to 43.3 (7 to 48) (p < 0.001). Radiological analysis was undertaken for 99 shoulders. This revealed humeral RLLs in one case (1%), glenoid RLLs in 15 cases (15.2%), and radiological rotator cuff failure in 22 cases (22.2%). Conclusion. This prospective cohort study shows encouraging short- to mid-term survivorship and clinical and radiological results for the Mathys Affinis Short, Short Stem Total Shoulder Prosthesis.

Abstract. Background. To determine the long-term survival outcomes of Copeland Resurfacing Hemiarthroplasty (CRHA) performed by a single surgeon series. Methods. A retrospective cohort study which looked at patients who underwent CRHA over 6 years. Re-operations including revisions with component exchange taking place in our hospital and at local centres were reviewed. Oxford Shoulder Score (OSS) was used to assess their functional outcomes pre- and post-CRHA. Results. 80 CRHAs were performed in 72 patients between 2007 and 2013 with a mean follow-up of 6.5 years. The mean follow-up was 79 months (50–122). The primary indication for CRHA was osteoarthritis (76.3%), cuff tear arthropathy (16.3%), rheumatoid arthritis (5%) and post-trauma (1.3%). The mean pre-operative OSS was 16, which doubled following CRHA surgery. Fifteen patients underwent revision surgery due to ongoing glenoid pain with a mean revision time following primary CRHA being 49 months. Projected survival at the endpoints 5,7 and 10 years were 83, 81 and 79% respectively. Conclusion. This study provides us with a much longer average follow-up period in comparison to many other studies published. Previous studies, support resurfacing as a useful implant in reducing pain and improving function in the short-term; but this series demonstrates over the medium-term a relatively high revision rate of about 20% in comparison with other arthroplasty options, despite the revision rate seeming to plateau from the 5-year mark onwards

Proximal humerus fracture dislocations are amongst the most severe proximal humerus injuries, presenting a challenging management problem. The aim of this study was to report on the long-term outcomes of the management of proximal humerus fracture dislocations. Patients with a proximal humerus fracture dislocation managed at a Level 1 trauma centre from January 2010 to December 2018 were included. Patients with an isolated tuberosity fracture dislocation or a pathological fracture were excluded. Outcome measures were the Oxford Shoulder Score (OSS), EQ-5D-5L, return to work, and radiological outcomes. Complications recorded included further surgery, loss of position/fixation, non-union/malunion, and avascular necrosis. A total of 69 patients were included with a proximal humerus fracture dislocation in the study period; 48 underwent surgical management and 21 were managed with closed reduction alone. The mean (SD) age of the cohort was 59.7 (±20.4), and 54% were male. Overall patients reported a mean OSS of 39.8 (±10.3), a mean EQ-5D utility score of 0.73 (±0.20), and 78% were able to return to work at a median of 1.2 months. There was a high prevalence of complications in both patients managed operatively or with closed reduction (25% and 38% respectively). In patients undergoing surgical management, 21% required subsequent surgery. Patient reported outcome measures post proximal humerus fracture dislocations do not return to normal population levels. These injuries are associated with a high prevalence of complications regardless of management. Appropriate patient counselling should be undertaken before embarking on definitive management

In recent years, use of anatomic stemless total shoulder arthroplasty (AsTSA) has increased. Despite evidence to suggest good mid-term results at 2-year follow-up there is a paucity of evidence for longer term follow-up. This study aimed to investigate outcomes at a minimum of 5 years post-operatively following primary AsTSA. This study is a retrospective case series of all patients who underwent a Mathys Affinis AsTSA from July 2010 (first case) to August 2018 (to allow minimum 5-year follow-up). Clinical outcomes included revision rate, range of motion and patient reported outcomes (Oxford Shoulder Score and Numerical Satisfaction Score). Radiological outcome was assessment of radiolucent lines for Lazarus grading. A total of 105 stemless TSAs were implanted. Five patients underwent revision (4.8%). Seventy-five AsTSA's were included in the final study for analysis of 5-year outcomes. Median follow-up time was 6.1 years. Median age was 69 years old and 81% were female. Oxford shoulder score showed a range of 18 to 48, with a median score of 47. Satisfied or very Satisfied was selected in 94.37%. Median range of motion assessments showed forward elevation 160°, abduction 150°, external rotation 40°, and mode internal rotation was to the lumbar spine. No glenoid lucency was present in 79.7%. There were 9.5% with Lazarus Grade 1 lucency, 5.4% with Lazarus Grade 2, and 5.4% Lazarus Grade 3. No humeral lucency was observed. This cohort study demonstrates promising clinical and radiological outcomes for the Mathys Affinis Stemless TSA at minimum 5 years post-operatively

Sub-acromial decompression surgery (SAD) has been widely used to treat shoulder impingement. Its validity has been questioned in multi-centric clinical trials and dissatisfaction rates can be high (35%). It is difficult to predict which patients will benefit operatively as research into predictive factors is limited. The study aim was to conduct a root-cause analysis of reasons for dissatisfaction in a cohort of operated patients. All patients with SAD dissatisfaction in the local Upper Limb database between 2015-19 (n=74/296) formed our study cohort. Patients were scored on Oxford shoulder score (OSS), QuickDASH score, EQ-5D-3L (TTO+VAS) at weeks 26 and 52 post-operatively. Patients' clinical history, radiographs, consultation and operative notes were reviewed. 28% of patients were dissatisfied with surgery. Mean age =52.3±13.4 years with equal gender distribution. 87% were operated arthroscopically. 67% were in physically demanding occupations. There was a significant increase in OSS and QuickDASH at weeks 26 and 52 post-operatively (p<0.05), similar improvement was not noted in VAS pain score. Pain followed by stiffness were the main contributors of dissatisfaction. Multiple implicating factors were noted, the most common being acromio-clavicular joint arthritis (25.7%), suggesting concomitant pathologies as an additional cause for patient dissatisfaction. This is the first study to evaluate reasons for dissatisfaction following SAD. We noted high rates (28%) of dissatisfaction and a predilection for those involved in physically demanding occupations. We recommend meticulous pre-operative workup to identify co-existing pathologies and appropriate pre-operative counselling to improve outcomes in selected patients needing SAD following failure of conservative management

In Australia nearly two-thirds of arthroplasty procedures are performed in the private setting, which is disproportionate to the dimensioning 43.5% of the population with private health cover. The rapid growth of shoulder arthroplasty surgery will be absorbed by both private and public sectors. This study aimed to assess the influence of healthcare setting on elective shoulder arthroplasty outcomes, defined by revision rate, and functional measures. Data was collected on all primary procedures performed from 2004 – 2019 within a regional area of Victoria, Australia. Patients were categorised into private or public settings. Trauma cases for acute proximal humerus fractures were excluded. The primary outcome of revision surgery was recorded as a cumulative percentage, and survival analysis conducted to calculate a hazard ratio (HR). Functional outcomes were measured through range-of-motion (ROM) and multiple validated patient-reported-outcome-measures (PROMs). 458 patients were identified in the study: 290 private and 168 public. There was no difference in the revision rate (3.8% private, 4.8% public), with an adjusted HR of 1.25 (p=0.66) for public compared to private. Baseline and post-operative functional measures were significantly greater in the private setting for ROMs and PROMs analysis, in particular post-operative QuickDASH (15.9±14.7 to 32.7±23.5; p<0.001) and Oxford Shoulder Score (42.6±6.3 to 35.7±11.2; p<0.001). However, there was no significant difference for any of the functional measures in the amount of change from baseline to 12-months between settings. Although healthcare setting does not appear to influence revision rate for shoulder arthroplasty, clear differences were demonstrated for functional measures both pre and post operatively. This may be attributed to factors such as access to perioperative rehabilitation and should be an area to target future investigations

A consecutive series of 372 patients who underwent surgery for disorders of the rotator cuff involving arthroscopic subacromial decompression and open or arthroscopic repairs of the cuff were prospectively investigated as to the comparability of subjective and objective assessment scores of shoulder function. Assessments were made before operation and at 3, 6, 12, 18 and 24 months after surgery using the Disabilities of the Arm, Shoulder, and Hand score, the Oxford shoulder score and the Constant-Murley score, which was used as a reference. All scores were standardised to a scale of 0 to 100 for comparison. Statistical analysis compared the post-operative course and the mean score for the subjective Disabilities to the Arm, Shoulder and Hand score and Oxford shoulder score, with the objective Constant score at each interval. A strong correlation was evident between both subjective scores and the Constant score. We concluded that both the subjective scores would be useful substitutes for the Constant score, obviating the need for a trained investigator and the specialist equipment required to perform the Constant score

The aim of this study was to determine the functional outcome and rate of re-tears following mini-open repair of symptomatic large and massive tears of the rotator cuff using a two-row technique. The 24 patients included in the study were assessed prospectively before and at a mean of 27 months (18 to 53) after surgery using the Constant and the Oxford Shoulder scores. Ultrasound examination was carried out at follow-up to determine the integrity of the repair. Patient satisfaction was assessed using a simple questionnaire. The mean Constant score improved significantly from 36 before to 68 after operation (p < 0.0001) and the mean Oxford Shoulder score from 39 to 20 (p < 0.0001). Four of the 24 patients (17%) had a re-tear diagnosed by ultrasound. A total of 21 patients (87.5%) were satisfied with the outcome of their surgery. The repair remained intact in 20 patients (83%). However, the small number of re-tears (four patients) in the study did not allow sufficient analysis to show a difference in outcome in relation to the integrity of the repair

A fracture of the tuberosity is associated with 16% of anterior glenohumeral dislocations. Manipulation of these injuries in the emergency department is safe with less than 1% risk of fracture propagation. However, there is a risk of associated neurological injury, recurrent instability and displacement of the greater tuberosity fragment. The risks and outcomes of these complications have not previously been reported. The purpose of this study was to establish the incidence and outcome of complications associated with this pattern of injury. We reviewed 339 consecutive glenohumeral dislocations with associated greater tuberosity fractures from a prospective trauma database. Documentation and radiographs were studied and the incidence of neurovascular compromise, greater tuberosity fragment migration and intervention and recurrent instability recorded. The mean age was 61 years (range, 18–96) with a female preponderance (140:199 male:female). At presentation 24% (n=78) patients had a nerve injury, with axillary nerve being most common (n=43, 55%). Of those patients with nerve injuries 15 (19%) did not resolve. Greater tuberosity displacement >5mm was observed in 36% (n=123) of patients with 40 undergoing acute surgery, the remainder did not due to comorbidities or patient choice. Persistent displacement after reduction accounted for 60 cases, later displacement within 6 weeks occurred in 63 patients. Recurrent instability occurred in 4 (1%) patients. Patient reported outcomes were poor with average EQ5D being 0.73, QDASH score of 16 and Oxford Shoulder Score of 41. Anterior glenohumeral dislocation with associated greater tuberosity fracture is common with poor long term patient reported outcomes. Our results demonstrate there is a high rate of neurological deficits at presentation with the majority resolving spontaneously. Recurrent instability is rare. Late tuberosity fragment displacement occurs in 18% of patients and regular follow-up for 6 weeks is recommended to detect this

Aim. Clavicular osteotomy was described as an adjunct to deltopectoral approach for improved exposure of the glenohumeral joint. This study aims to present contemporary outcomes and complications associated with the routine use of clavicular osteotomy by a single surgeon in a regional setting within New Zealand. Methods. A retrospective case series of patients who have undergone any shoulder arthroplasty for any indication between March 2017 to August 2022. This time period includes all patients who had clavicular osteotomy(OS) and patients over an equal time period prior to the routine use of osteotomy as a reference group (N-OS). Oxford Shoulder Score (OSS) and a Simple Shoulder Test (STT) were used to assess functional outcomes and were compared with the reported literature. Operative times and Complications were reviewed. Results. 66 patients were included in the study. 33 patients in the OS group and 33 in the N-OS group. No difference in age, sex, indications for operative intervention and the surgery provided was identified. No significant difference in operative time between groups (N-OS 121 minutes; OS 128 minutes). No clinically significant difference was identified in the OSS (N-OS; mean 38 vs OS 39) or the STT (N-OS 8.3 vs OS 9). The outcomes scores of both groups are in keeping with published literature. Two post operative clavicle fractures, one prominent surgical knot occurred in the OS that required further surgical intervention. Two cases of localized pain over the clavicle and one case of the prominent lateral clavicle were reported in the OS group. Two cases of localized pain over clavicle reported in the N-OS group. Conclusion. Use of clavicular osteotomy is not associated with inferior patient reported. The osteotomy introduces specific risks, however, the study provides evidence that these complications are infrequent and avoidable. Surgeons should feel confident in using this adjunct when exposure to the shoulder is difficult

There is very limited literature describing the outcomes of management for proximal humerus fractures with more than 100% displacement of the head and shaft fragments as a separate entity. This study aimed to compare operative and non-operative management of the translated proximal humerus fracture. A prospective cohort study was performed including patients managed at a Level 1 trauma centre between January 2010 to December 2018. Patients with 2, 3 and 4-part fractures were included based on the degree of translation of the shaft fragment (≥100%), resulting in no cortical contact between the head and shaft fragments. Outcome measures were the Oxford Shoulder Score (OSS), EQ-5D-5L, and radiological outcomes. Complications recorded included further surgery, loss of position/fixation, and non-union/malunion. Linear and logistic regression models were used to compare management options. There were 108 patients with a proximal humerus fracture with ≥100% translation; 76 underwent operative management and 32 were managed non-operatively with sling immobilisation. The mean (SD) age in the operative group was 54.3 (±20.2) and in the non-operative group was 73.3 (±15.3) (p<0.001). There was no association between OSS and management options (mean 38.5(±9.5) operative vs mean 41.3 (±8.5) non-operative, p=0.48). Operative management was associated with improved health status outcomes; EQ-5D utility score adjusted mean difference 0.16 (95%CI 0.04-0.27, p=0.008); EQ-5D VAS adjusted mean difference 19.2 (95%CI 5.2-33.2, p=0.008). Operative management was further associated with a lower odds of non-union (adjusted OR 0.30, 95%CI 0.09-0.97, p=0.04), malunion (adjusted OR 0.14, 95%CI 0.04-0.51, p=0.003) and complications (adjusted OR 0.07, 95%CI 0.02-0.32, p=0.001). Translated proximal humerus fractures with ≥100% displacement demonstrate improved health status and radiological outcomes following surgical fixation. Patients with this injury should be considered for operative intervention

The purpose of this study is to report the clinical and radiological outcomes of patients undergoing primary or revision reverse total shoulder arthroplasty using custom 3D printed components to manage severe glenoid bone loss with a minimum of 2-year follow-up. After ethical approval (reference: 17/YH/0318), patients were identified and invited to participate in this observational study. Inclusion criteria included: 1) severe glenoid bone loss necessitating the need for custom implants; 2) patients with definitive glenoid and humeral components implanted more than 2 years prior; 3) ability to comply with patient reported outcome questionnaires. After seeking consent, included patients underwent clinical assessment utilising the Oxford Shoulder Score (OSS), Constant-Murley score, American Shoulder and Elbow Society Score (ASES), and quick Disabilities of the Arm, Shoulder, and Hand Score (quickDASH). Radiographic assessment included AP and axial projections. Patients were invited to attend a CT scan to confirm osseointegration. Statistical analysis utilised included descriptive statistics (mean and standard deviation) and paired t test for parametric data. 3 patients had revision surgery prior to the 2-year follow-up. Of these, 2/3 retained their custom glenoid components. 4 patients declined to participate. 5 patients were deceased at the time of commencement of the study. 21 patients were included in this analysis. The mean follow-up was 36.1 months from surgery (range 22–60.2 months). OSS improved from a mean 16 (SD 9.1) to 36 (SD 11.5) (p < 0.001). Constant-Murley score improved from mean 9 (SD 9.2) to 50 (SD 16.4) (p < 0.001). QuickDASH improved from mean 67 (SD 24) to 26 (SD 27.2) (p = 0.004). ASES improved from mean 28 (SD 24.8) to 70 (SD 23.9) (p = 0.007). Radiographic evaluation demonstrated good osseointegration in all 21 included patients. The utility of custom 3D-printed components for managing severe glenoid bone loss in primary and revision reverse total shoulder arthroplasty yields significant clinical improvements in this complex patient cohort

Abstract. Background. The influence of diagnosis on outcomes after reverse shoulder arthroplasty (RSA) is not completely understood. The purpose of this study was to compare clinical outcomes of different pathologies. Methods. A total of 78 RSAs were performed for the following diagnoses: (1) rotator cuff tear arthropathy(RCA), (2) massive cuff tear(MCT) with osteoarthritis(OA), (3) MCT without OA, (4) arthritis, (5) acute proximal humerus fracture. Mean follow up 36 months (upto 5 years) Range of motion, Oxford Shoulder Score were obtained preoperatively and postoperatively. Results. Mean OSS was 30. The RCA, MCT-with-OA, MCT-without-OA, and arthritis groups all exhibited significant improvements in all outcome scores and in all planes of motion. After adjustment for age and compared with RCA, those with OA had significantly better abduction (P < .05), and those with fractures had significantly worse patient satisfaction (P < .05). Among male patients, those with MCTs without OA had significantly worse satisfaction (P < .05). Conclusion. RSA reliably provides improvement regardless of preoperative diagnosis. Although subtle differences exist between male and female patients, improvements in clinical outcome scores were apparent after RSA

The Delta total shoulder replacement is a reversed, semi-constrained prosthesis and is recommended for the management of rotator cuff arthropathy and other difficult reconstructive shoulder problems. It was initially advised to use this prosthesis in patients older than 75. There were reports saying the complication rates of this prosthesis are high and patients' satisfaction and functional outcome is far from being satisfactory. In our study we wanted to evaluate results and complications of reverse shoulder arthroplasty in practice of single surgeon. In our study we reviewed patients who had reverse shoulder arthroplasty performed between 2001 and 2009. We evaluated them clinically and radiologically. We measured functional outcome using Constant score, we used Oxford Shoulder score to measure patients' subjective outcome. We compared our results to pre-operative Oxford Shoulder score (unfortunately no pre-op constant score was done). X-rays were assessed by independent surgeon who was not involved in care of the patients. Out of 36 reverse shoulder replacements performed by Mr. Sinha from 2001 to 2009 we managed to review in clinic 29 shoulders. 3 patients died from causes not related to surgery, 3 patients were too unwell to attend clinic, we lost 1 patient to follow up. Mean time from operation to follow up was 33 months (range 6 to 82 months). Average patients' age at time of surgery was 73,4 years (range: 44 to 90). Indications included rotator cuff arthropathy (86%), other indications were trauma (10%) and revision of failed hemiarthroplasty (4%). There were neither revisions nor infections in our group. There was 1 dislocation that occurred after operation, this was reduced under GA and never re-dislocated again. 12 patients (41%) were very pleased with result of surgery, 15 patients (52%) were satisfied and 2 patients said surgery did not meet their expectations. Mean Shoulder Oxford score improved from 20.8 (range 2 to 36) pre-operatively to 36.7 (range 20 to 48) during follow up. 3 patients had Oxford Shoulder score of 48 (maximum). Oxford shoulder score deteriorated in 2 cases (one in case when replacement was done to treat fracture). Post operative Constant score was 65.5. All patients but one declared overall improvement. 10 patients (34%) reported no pain at all. 5 patients who were 65 years old or younger at time of surgery did well and improved their shoulder function. In our experience reverse geometry shoulder replacement is a very good solution for rotator cuff arthropathy. Results in proximal humeral fracture are worse, but the number of patients we had was small and our experience is limited. Mid term results are very satisfactory overall, even in younger and more demanding patients. The complications were rare and overall patients' satisfaction very high. We think more research needs to be done to asses long term results, especially in younger population

Aims. The aim of this study was to investigate the influence of age on the cost-effectiveness of arthroscopic rotator cuff repair. Patients and Methods. A total of 112 patients were prospectively monitored for two years after arthroscopic rotator cuff repair using the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), the Oxford Shoulder Score (OSS), and the EuroQol five-dimension questionnaire (EQ-5D). Complications and use of healthcare resources were recorded. The incremental cost-effectiveness ratio (ICER) was used to express the cost per quality-adjusted life-year (QALY). Propensity score-matching was used to compare those aged below and above 65 years of age. Satisfaction was determined using the Net Promoter Score (NPS). Linear regression was used to identify variables that influenced the outcome at two years postoperatively. Results. A total of 92 patients (82.1%) completed the follow-up. Their mean age was 59.5 years (. sd. 9.7, 41 to 78). There were significant improvements in the mean DASH (preoperative 47.6 vs one-year 15.3; p < 0.001) and OSS scores (26.5 vs 40.5; p < 0.001). Functional improvements were maintained with no significant change between one and two years postoperatively. The mean preoperative EQ-5D was 0.54 increasing to 0.81 at one year (p < 0.001) and maintained at 0.86, two years postoperatively. There was no significant difference between those aged below or above 65 years of age with regards to postoperative shoulder function or EQ-5D gains. Smoking was the only characteristic that significantly adversely influenced the EQ-5D at two years postoperatively (p = 0.005). A total of 87 were promoters and five were passive, giving a mean NPS of 95 (87/92). The total mean cost per patient was £3646.94 and the mean EQ-5D difference at one year was 0.2691, giving a mean ICER of £13 552.36/QALY. At two years, this decreased further to £5694.78/QALY. This was comparable for those aged below or above 65 years of age (£5209.91 vs £5525.67). Smokers had an ICER that was four times more expensive. Conclusion. Arthroscopic rotator cuff repair results in excellent patient satisfaction and cost-effectiveness, regardless of age. Cite this article: Bone Joint J 2019;101-B:860–866

Abstract. Shoulder replacements have evolved and current 4th generation implants allow intraoperative flexibility to perform anatomic, reverse, trauma, and revision shoulder arthroplasty. Despite high success rates with shoulder arthroplasty, complication rates high as 10–15% have been reported and progressive glenoid loosening remains a concern. Objectives. To report medium term outcomes following 4th generation VAIOS® shoulder replacement. Methods. We retrospectively analysed prospectively collected data following VAIOS® shoulder arthroplasty performed by the senior author between 2014–2020. This included anatomical (TSR), reverse(rTSR), revision and trauma shoulder replacements. The primary outcome was implant survival (Kaplan-Meier analysis). Secondary outcomes were Oxford Shoulder Scores (OSS), radiological outcomes and complications. Results. 172 patients met our inclusion criteria with 114 rTSR, 38 anatomical TSR, and 20 hemiarthroplasty. Reverse TSR- 55 primary, 31 revision, 28 for trauma. Primary rTSR- 0 revisions, average 3.35-year follow-up. Revision rTSR-1 revision (4.17%), average 3.52-year follow-up. Trauma rTSR- 1 revision (3.57%), average 4.56-year follow-up OSS: Average OSS improved from 15.39 to 33.8 (Primary rTSR) and from 15.11 to 29.1 (Revision rTSR). Trauma rTSR-Average post-operative OSS was 31.4 Anatomical TSR38 patients underwent primary anatomical TSR, 8 were revisions following hemiarthroplasty. In 16/38 patients, glenoid bone loss was addressed by bone grafting before implantation of the metal back glenoid component. Mean age at time of surgery was 68.3 years (53 – 81 years). Mean follow-up was 34 months (12 – 62 months). The average Oxford shoulder score improved from 14 (7–30) to 30 (9–48). There were 3 revisions (7.8%); two following subscapularis failure requiring revision conversion to reverse shoulder replacement and one for glenoid graft failure. Conclusions. The medium-term results of the VAIOS® system suggest much lower revision rates across multiple configurations of the system than previously reported, as well as a low incidence of scapular notching. This system allows conversion to rTSR during primary and revision surgery

Abstract. Background/Objectives. The incidence of reverse total shoulder replacement (rTSR) implantation is increasing globally, but apprehension exists regarding complications and associated challenges. We retrospectively analysed the senior author's series of rTSR from a tertiary centre using the VAIOS shoulder system, a modular 4th generation implant. We hypothesised that the revision rTSR cohort would have less favourable outcomes and more complications. Methods. 114 patients underwent rTSR with the VAIOS system, over 7 years. The primary outcome was implant survival. Secondary outcomes were Oxford shoulder scores (OSS), radiographic analysis (scapular notching, tuberosity osteolysis, and periprosthetic radiolucent lines) and complications. Results. There were 55 Primary rTSR, 31 Revision rTSR and 28 Trauma rTSR. Implant survival: Primary rTSR- 0 revisions, average 3.35-year follow-up. Revision rTSR-1 revision (4.17%), average 3.52-year follow-up. Trauma rTSR- 1 revision (3.57%), average 4.56-year follow-up OSS: Average OSS improved from 15.39 to 33.8 (Primary rTSR) and from 15.11 to 29.1 (Revision rTSR). Average post-operative OSS for the Trauma rTSR was 31.4 Radiological analysis and complications: Low incidence of scapular notching One hairline fracture below the tip of stem, noted incidentally, which required no treatment. One periprosthetic fracture after alcohol related fall. Treated non-surgically One joint infection requiring two-stage revision to rTSR. One dislocation noted at 2 year follow up. This patient had undergone nerve grafting within 6 months of rTSR for axillary nerve injury sustained during the original fracture dislocation. One acromial fracture with tibial and distal humeral fracture after a fall. Conclusions. The 4th generation modular VAIOS implant is a reliable option for various indications. The revision rTSR cohort had favourable outcomes with low complication rates. In this series, early-to-medium term results suggest lower revision rates and good functional outcomes when compared to published reports. We plan to monitor long-term implant survivorship and patient reported outcomes. Declaration of Interest. (a) fully declare any financial or other potential conflict of interest

The purpose of this study is the evaluate the net promotor score of arthroscopic subacromial decompression and rotator cuff repair. The Friends and Family Test, a variant of the Net Promoter Score, was adapted for the National Health Service to evaluate overall patient satisfaction and how likely patients are to recommend an intervention. It ranges from −100 to 100. Positive scores indicate good performance. This study quantifies the scores in 71 patients at 1 year following arthroscopic sub acromial decompression and rotator cuff repair. All of the procedures were performed by 1 consultant shoulder specialist. The patient filled out a shoulder questionnaire pre-operatively, at 6 months and 1 year. The score was 72 for subacromial decompression (n = 32) and 85 for rotator cuff repair +/− decompression (n = 39). Oxford shoulder score was also taken and had a rise of 4.3 and 6.9 respectively. Our study indicates that these procedures are highly valued and are recommended by patients according to the Friends and Family Test. The results of the Friends and Family Test correlated well with postoperative functional improvement and satisfaction. We conclude from this study that a compound score based on the Friends and Family Test is a useful addition to traditional measures of patient satisfaction

The aim of this study was to observe the macroscopic and microscopic appearance of the Coracoacromial ligament and Subacromial bursa during Subacromial decompression and correlate it with the outcome at 3 months. Twenty patients with Subacromial Impingement without Rotator Cuff tear and five patients with large/massive irreparable Rotator Cuff tears who underwent a Subacromial Decompression. Patients with other shoulder pathology were excluded. Patients completed an Oxford Shoulder Score pre-operatively and their injection history was noted. At operation the shape of the acromion was noted. The macroscopic appearance of the CA ligament and the Subacromial bursa was classified as normal, mild/moderate and severe. Biopsies of the Subacromial bursa and CA ligament were taken and were analysed using histological and contempory immunocytochemical techniques. A histological analysis was performed using Mayer’s Haemotoxylin and Eosin, Toluidine Blue and Congo Red. Sections were stained with primary antibodies against PCNA (Proliferating cell nuclear antigen), Mast Cell Tryptase, CD3 (T-cell), CD20 (B cell), CD 34 (QBEnd 10), CD45 (Leucocyte Common Antigen), CD68 and D2–40 (Lymphatic Endothelial Marker). Post operatively the patients completed an Oxford Shoulder Score at 3 months. All the patients demonstrated an improvement in their Oxford Shoulder Score. The histological analysis demonstrated thickening of the synovial membrane and increased vascularity within the bursa and ligament. Increased numbers of inflammatory cells were present within the ligament and bursa of patients with impingement compared with massive rotator cuff tears. There was a relationship between outcome and the appearance of the bursa and ligament

Aim: To assess the clinical and functional outcome of proximal humeral fractures (2,3 and 4 parts) fixation with PHILOS (Proximal Humeral interlocked Osteosynthesis) plate using Oxford and DASH scoring system. Methods: Forty-eight consecutive patients were treated with PHILOS plate from the complex proximal humeral fractures. One senior surgeon, using PHILOS plates, operated all patients. The patients were regularly assessed clinically, and plain radiographic evaluation was performed for fracture healing, avascular necrosis, and implant failure. Clinical outcome was measured using Oxford shoulder scores and DASH (Disability of the arm, shoulder, and hand) scores. Patients, who died, lost the follow up or the follow up was less than 3 months were excluded from the study. Results: There were nine male patients (Age: 29–89 yrs) and twenty-nine female patients (Age: 35–93 yrs). Average age: 65 yrs. 74% were two part and three part fractures. Five patients died and four were lost in follow-up. These patients were excluded from the study. Mean follow-up time: 21.7 months (range: 6–44 months). Mean oxford shoulder scores: 41.8 (range: 14–60), Mean DASH scores: 30.2 (range: 0–83.3). There were no cases of non-union. Two plates were removed after fracture healing for complications of impingement and screw cutout. Discussion & conclusion: Proximal humeral fractures constitute 5–7% of all fractures and 26% of humeral fractures.13–16% of proximal humeral fractures are 3 & 4 parts. Proximal humeral fractures have been a challenge to acquire stable fixation. Difficulties have been multifactorial, including osteoporotic bone, angular instability and non-availability of the low-profile implant to avoid impingements. PHILOS plate having locking screws provides angular stability and better hold in osteoporotic bone. It is low profile, which avoids subacromial impingement. Multiple holes in the proximal part of plate for suture anchors helps for soft tissue augmentation. PHILOS plate can provide an excellent stable construct even in multifragmented Osteoporotic proximal humeral fractures. Our study has shown that PHILOS plates are reliable implants for internal fixation of proximal humerus fractures. An inverse correlation was seen between oxford shoulder scores and DASH scores. Patients with higher oxford scores indicating a good outcome had lesser disability scores. Comminuted fractures (four part fractures) had less than satisfactory shoulder scores and higher disability scores. In general, younger patients did better than older patients. This study demonstrates that PHILOS plates provide stable internal fixation for proximal humerus fractures. Age and fracture configuration play a significant role in the clinical outcome of these fractures after internal fixation

Contoured locking plates are commonly used to fix the proximal humerus fractures. Their long-term results are unknown. We present long-term radiological and functional outcome of three and four part fractures of the proximal humerus treated with PHILOS plate. We prospectively analysed 53 consecutive three and four part proximal humerus fractures treated with PHILOS plate between 2002 and 2007. Patients were assessed using Oxford Shoulder Score and DASH score. 44 fractures (21 three part and 23 four part) were available at the final follow up. At a mean follow-up of 8.5 years (6.4 years–10.8 years) the average Oxford Shoulder Score was 43.9 (range 23–48) and the average DASH score was 7.7 (range 0–36.7). 30% of patients required re-operation (five for hemiarthroplasty, three for impingement syndrome, five for removal of implant). Avascular necrosis (AVN) developed in 10 patients, of which only three required hemiarthroplasty. All except one patient were satisfied with the result of their operation. Our study supports the use of locking plates for the treatment of three and four part proximal humeral fractures. In spite of some patients requiring secondary surgical intervention in the first few years, the function of the shoulder continues to improve and in the long term patients were satisfied with the outcome. An important finding of our study is that the post-traumatic AVN of humeral head does not necessarily need major surgical intervention. We believe that the possibility of avascular necrosis should not be a major determinant in the choice of surgical treatment of proximal humeral fractures

Shoulder resurfacing arthroplasty is a bone conserving option for patients with glenohumeral arthritis. We report the early results of this procedure at our unit with a minimum follow up of 2 years (mean follow up of 36 months). A historical analysis of prospectively collected clinical data was reviewed on a consecutive series of 22 patients (mean age of 73 years) with end stage gleno-humeral arthrosis who had undergone humeral resurfacing hemiarthroplasty performed by a single surgeon. Pain and function were assessed using the Oxford shoulder score and patient satisfaction was recorded. Radiographs were evaluated for implant loosening. 82% of patients had significant improvement in their oxford shoulder score from pre-operatively to two years post-operatively. Complications included one case of intra-operative conversion to a stemmed hemiarthroplasty due to fracture of the humeral head, one case of adhesive capsulitis that required MUA and arthroscopic capsular release and two cases of revision to a total shoulder replacement for pain. Humeral resurfacing arthroplasty is a viable treatment option for glenohumeral arthritis with good short term results

Purpose:. To review the union rates, outcomes and complications of angular stable plating of lateral third clavicle fractures. Method:. Between 2007 and 2010 angular stable plates were used in the fixation for seventeen patients with displaced lateral third clavicle fractures (Allman Group II, Type 2). These were identified from surgical log books and operation codes. The surgical and clinical notes as well as X-rays were reviewed. The patients were contacted telephonically. An Oxford Shoulder Score and questions relating to plate removal, scar pain and return to activities were asked. Three patients were not contactable. Results:. There were 16 males. The average age was 44. The average time to union was 3 months (range 2 to 4). There were no complications. The average Oxford Shoulder Score was 13 (range 12–19). No plates have required removal but 2 patients have requested removal for discomfort. All but 3 patients have returned to full activity. Conclusion:. The use of angular stable plates for fixation of type 2 lateral end of clavicle fractures results in excellent union rates by 3 months with only 3 patients requesting elective plate removal. This is in contrast to hook plates which require mandatory removal. No other complication was encountered

Massive tears of the supraspinatus of the rotator cuff lead to painful loss of movement. The literature supports repair of these tears for young healthy individuals, however they present a surgical challenge with historically poor results from both athroscopic and standard open techniques. Prof Bunker has developed a surgical technique for massive rotator cuff tears with a Grammont Osteotomy of the spine of the acromion, when standard surgical techniques will not allow the necessary exposure: the so called “Full Monty”. Patients were entered in to a prospective study to obtain the functional benefit of this procedure. Each patient had a pre-operative American Shoulder Elbow Score (ASES) Oxford Shoulder score (OSS), pain score, range of movement. Post-operatively these measures were repeated along with a patient questionnaire on function and satisfaction. The mean American Shoulder score (ASS) preoperatively was 7 (out of a possible 30) and improved postoperatively to 23(P = 0.00011). The improvement in the Oxford Shoulder Score was 22 (out of a possible 48) preoperatively to 43 postoperatively (0.0001) and 80% patients stated their treatment was “successful”. We believe this a successful surgical option for a patient with “massive” rotator cuff tear that is not amenable to standard surgical techniques

Introduction. Resurfacing of the glenohumeral joint has gained popularity since its first introduction in 1958. Advantages of resurfacing over conventional shoulder arthroplasty include preservation of humeral bone stock, closer replication of individual anatomy, reduction of periprosthetic fracture risk, non-violation of medullary canal, and ease of revision to a stemmed component if needed. Materials and Methods. We reviewed a group of patients with arthrosis of the glenohumeral joint who underwent humeral resurfacing, and who were at a minimum of two years post surgery. From January 2000 to March 2011, 51 humeral resurfacing procedures were performed in 49 patients. Patients were contacted for review, and assessed using patient reported outcome measures. An Oxford Shoulder score as well as a subjective satisfaction and outcome questionnaire was completed, as well as details regarding further surgery or revision. 2 patients had died, 11 patients were not contactable, and in 4 the medical files had been lost. In the remaining 32 shoulders, the average follow-up was 5.9 years. The mean age at time of surgery was 62.3 years (range 36 to 84). Results. Complications included 7 revisions (average 2.4 years post surgery), a further 2 patients await revision. There were 2 subscapularis tendon ruptures managed operatively. A further 2 patients required surgery – one for impingement and acromioclavicular joint arthrosis, and the other for instability. The mean Oxford Shoulder score in the unrevised shoulders was 35.4 (range 10 to 47). Conclusion. We have encountered a high rate of revision in patients undergoing humeral resurfacing for glenohumeral arthrosis. In those who have not been revised, there is a wide spread of patient satisfaction as evidenced by the subjective outcome scores. NO DISCLOSURES

Background. Nonsurgical treatment of Acromioclavicular joint dislocations is well established. Most patients treated conservatively do well, however, some of them develop persistent symptoms. We have used two different surgical reconstruction techniques for Chronic ACJ dislocation stabilization. The study evaluates the effectiveness of a braided polyester prosthetic ligament and modified Weaver-Dunn reconstruction methods. Methods. 55 patients (mean age 42) with Chronic Acromioclavicular joint dislocation were included in this study. They were treated either by a modified Weaver-Dunn method or a braided polyester prosthetic ligament. Patients were assessed using Oxford shoulder score preoperatively and a minimum of 12 months postoperatively. Results. 31 patients (mean age 40, M=24, F=7) were treated by Modified WD method and 24 patients (mean age 44, M=18, F=6) by Surgilig at a mean21 and 24 months post injury. The mode of injury, presentation of symptoms, grade of injury and mean time at surgery post injury was similar in both the groups. There was a significant improvement (p<0.05) in mean pre and postoperative Oxford Shoulder score in both the groups (WD Mean preop OSS=28, postop OSS= 42, Surgilig Mean preop OSS=26, postop OSS=45). The Surgilig group returned to work significantly earlier (Surgilig; mean 6 wks, WD mean 14 wks). There were 3 failures in the WD group and 1 in Surgilig. Superficial infection was seen in 3 patients requiring antibiotics only. Most of the patients from both groups were satisfied with their result except for 3 patients, one which developed complex regional pain syndrome and two developed secondary shoulder problems resulting in ongoing pain. Conclusions. Chronic ACJ dislocations can be successfully treated surgically by either Weaver-Dunn or Surgilig based on similar satisfaction scores amongst patients of both groups. In this study Surgilig had higher overall success rate, less incidence of failure and allowed earlier return to work

Mid-shaft humeral fractures in adults are common these days and often present with a management dilemma between operative and non-operative treatment. This study evaluates the outcome of such fractures treated non-operatively over a span of 10 years. In this retrospective study, a review of case notes and radiographs of patients whose mid-shaft humerus fractures were treated non-operatively between 1994 and 2004 was done. Those younger than 16 years and/or who had surgery primarily were excluded. Various factors including patient demographics, mechanism of injury, AO fracture classification and time to union were studied. Mean patient follow-up was 4 years and 6 months. The Oxford shoulder score was used for functional assessment. There was a total of 43 patients, mostly men with involvement of the dominant arm. 5 patients required open reduction and internal fixation with bone grafting for non-union. The average Oxford shoulder score was 18. The majority of patients could resume their jobs and the average time to union was 9 weeks. We conclude from this study that there is a high union rate in the mid-shaft humeral fractures in adults treated non-operatively, with an acceptable functional outcome

Glenohumeral dislocation is complicated with a greater tuberosity fracture in 16% of cases. Debate regarding the safety of closed reduction in the emergency department exists, with concerns over fracture propagation during the reduction manoeuvre. The study aim was to report the results of closed reduction, identify complications and define outcome for these injuries. 188 consecutive glenohumeral dislocations with a tuberosity fracture were identified from a prospective database from 2014–2017. 182 had an attempted closed reduction under appropriate sedation using standard techniques, five were manipulated in theatre due to contra-indications to sedation. Clinical, radiographic and patient reported outcomes, in the form of the QuickDASH and Oxford Shoulder Score (OSS), were collected. A closed reduction in the emergency department was successful in 162 (86%) patients. Two iatrogenic fractures of the proximal humerus occurred, one in the emergency department and one in theatre, representing a 1% risk. 35 (19%) of patients presented with a nerve lesion due to dislocation. Surgery was performed in 19 (10%) cases for persistent or early displacement (< 2 weeks) of the greater tuberosity fragment. Surgery resulted in QuickDASH and OSS scores comparable to those patients in whom the tuberosity healed spontaneously in an anatomical position (p=0.13). 18 patients developed adhesive capsulitis (10%). Glenohumeral dislocation with greater tuberosity fracture can be safely treated by closed reduction within the emergency department with a low risk of humeral neck fracture. Persistent or early displacement of the tuberosity fragment will occur in 10% of cases and is an indication for surgery

Adhesive capsulitis of the shoulder is a common debilitating condition with prevalence in the order of 2 to 5%. Whilst it is usually a self-limiting condition, patients are typically not willing, nor are they able, to wait to the end of the recovery phase. A number of treatment strategies have been described. Manipulation under anaesthesia can significantly increase motion in all planes, but carries a significant risk of fracture. Capsular release also significantly improves motion with fewer potential side effects. We hypothesise that performing an arthroscopic excision of the abnormal capsulitis tissue will give better results with least risk of recurrence. Data was collected both retrospectively and prospectively for patients undergoing this procedure. Range of motion and Oxford shoulder scores was documented pre-operatively and post-operatively, at 6 weeks, 3 months and 6 months. 41 patients were included. At 3 months mean flexion had increased from 101 to 152 degrees, abduction from 91 to 151 degrees, and external rotation from 18 to 44 degrees. Mean Oxford shoulder score had increased from 20.6 to 35.8 at 3 months. The results support the use of this technique for treating adhesive capsulitis. Larger patient numbers and longer term follow up will help compare it against the other well established techniques

Controversy surrounds the management of displaced three- and four-part fractures of the proximal humerus. The percutaneous Resch technique of stabilisation involves minimal soft-tissue dissection and a reduced risk of stiffness and avascular necrosis. However, it requires a second operation to remove Kirschner wires and the humeral block. We describe a modification of this technique that dispenses with the need for this second operation and relies on a sequential pattern of screw placement. We report the outcome of 32 three- or four-part fractures of the proximal humerus treated in this way at a mean follow-up of 3.8 years (2 to 8)). There were 14 men and 18 women with a mean age of 56 years (28 to 83). At final follow-up the mean Oxford shoulder scores were 38 (31 to 44) and 39 (31 to 42), and the mean Constant scores were 79 (65 to 92) and 72 (70 to 80) for three- and four-part fractures, respectively. We further analysed the results in patients aged < 60 years with high-energy fractures and those aged ≥ 60 years with osteoporotic fractures. There were no cases of nonunion or avascular necrosis. The results were good and comparable to those previously reported for the Resch technique and other means of fixation for proximal humeral fractures. We would recommend this modification of the technique for the treatment of displaced three-part and four-part fractures in patients both younger and older than 60 years of age

Introduction. Snapping scapula symptoms occur due to disruption of the smooth gliding motion between scapula and thoracic cage. Patients present with pain in the scapulothoracic area aggravated by overhead and repetitive shoulder movements. It is often associated with audible and palpable crepitus, clicking, crunching, grating or snapping sensation. Open or arthroscopic scapulothoracic surgical treatment is an option when non-operative treatment modalities fail. The aim of our study was to assess the outcome of scapulothoracic arthroscopic treatment in patients with painful snapping scapula. Methods. Eight patients underwent scapulothoracic arthroscopic treatment for painful snapping scapula. Pre-operatively, all these patients had a trial of conservative treatment modalities for at least 6 months, consisting of activity modification, analgesia and physiotherapy for restoration of normal scapulothoracic kinematics. All patients had a temporary pain relief following a local anaesthetic and steroid injection. We graded the crepitus from 0 to 3 - 0 being no crepitus, 1 being palpable but not audible crepitus, 2 being soft audible crepitus and 3 being loud crepitus. Operations were performed with the patients in either prone or semi-prone position. The arm was placed in the “chicken wing” position (arm in full internal rotation with the hand placed on the back), so that the scapula lifted up from the chest wall. Two portals along the medial border of scapula were used for arthroscopy and instrumentation. In two cases a superior portal was also used. Outcome was assessed by pre and postoperative visual analogue score (VAS) and Oxford Shoulder Score. Pre and postoperative scores were compared using paired t-test. The significance level was set at P <. 05. Results. Of the eight patients included in our study, two were male and six were female patients. Mean age at the time of surgery was 26 years (range 16–34 years). Based on the preoperative clinical and MRI/CT findings and intra-operative arthroscopic findings, five had scapulothoracic bursectomy and 3 had bursectomy and shaving of superomedial border of scapula. Mean follow up was 5 months (Range 2 to 7 months). VAS score improved significantly from a mean of 9.4 preoperatively to 2.4 (P value .0002). There was also a significant improvement in Oxford Shoulder Score from a mean of 8.7 pre-operatively to 34.7 post operatively (P= .0001). Mean crepitus score significantly decreased from 2.6 to 0.3 (p <.0001). In six patients crepitus completely resolved. In two there was residual palpable crepitus but they had good pain relief. All eight patients were happy with the outcome of their surgery and will recommend this procedure to patients with similar symptoms. Conclusion. Arthroscopic scapulothoracic treatment provides significant pain relief and functional improvement for painful snapping scapula symptoms not responding to non surgical treatment modalities

The treatment of massive rotator cuff tears remains controversial. There is lack of studies comparing patient-reported outcomes (PROM) of arthroscopic massive rotator cuff repairs (RCR) against large, medium and small RCRs. Our study aims to report the PROM for arthroscopic massive RCR versus non-massive RCR. Patients undergoing an arthroscopic RCR under a single surgeon over a 5-year period were included. Demographic data were recorded. Pre-operative Quick-DASH and Oxford Shoulder Score (OSS) were prospectively collected pre-operatively and at final review (mean of 18 months post-operatively). The scores were compared to a matched cohort of patients who had large, medium or small RCRs. A post-hoc power analysis confirmed 98% power was achieved. 82 patients were included in the study. 42 (51%) patients underwent massive RCR. The mean age of patients undergoing massive RCR was 59.7 and 55% (n=23) were female. 21% of massive RCRs had biceps augmentation. Quick-DASH improved significantly from a mean of 46.1 pre-operatively to 15.6 at final follow-up for massive RCRs (p<0.001). OSS improved significantly from a mean of 26.9 pre-operatively to 41.4 at final follow up for massive RCRs (p<0.001). There was no significant difference in the final Quick-DASH and OSS scores for massive and non-massive RCRs (p=0.35 and p=0.45 respectively). No revision surgery was required within the minimum one year follow up timescale. Arthroscopic massive rotator cuff repairs have no functional difference to non-massive rotator cuff repairs in the short term follow up period and should be considered in appropriate patient groups

The management of patients with massive irreparable rotator cuff tears (RCT) has traditionally proved challenging. This prospective study was undertaken with the aim to assess the overall functional outcome following the use of human dermal allograft in the reconstruction of massive irreparable RCT. 15 patients were included in the study, having a median age of 63 years. All patients underwent open reconstruction of massive irreparable RCT. None of the selected patients had evidence of significant gleno-humeral arthritis. All patients were evaluated pre- and post- operatively by the treating surgeon, and followed up for 12 months. The same physiotherapy protocol was prescribed for all patients. Initial and follow-up assessments were done at regular intervals using the Oxford and quick-DASH scoring systems. A very high patient satisfaction rate, with substantial improvement in pain and function was noted. There was substantial improvement in Oxford shoulder score from a mean of 23.3 to 8.7 (p<0.01), and a similar improvement in mean quick-DASH score from 50.3 to 23.0 (p<0.01). Of the 15 patients, 11 had an improvement of >10 in Oxford score, with these reporting a score of <10 after 12 months. None of the patients had any significant complications because of the surgery, and none had a deterioration in Oxford score from their pre-operative status. We found that Human dermal allograft is a very effective tool in the repair of massive irreparable RCT, with excellent follow-up results after one year

Introduction. The use of reverse total shoulder arthroplasty (RSA) is becoming increasingly common in the treatment of rotator cuff arthropathy. Standard RSA technique involves medialising the centre of rotation (COR) maximising the deltoid lever arm and compensating for rotator cuff deficiency. However reported complications include scapular notching, prosthetic loosening and loss of shoulder contour. As a result the use of Bony Increased Offset Reverse Shoulder Arthroplasty (BIO-RSA) has been gaining in popularity. The BIO-RSA is reported to avoid these complications by lateralising the COR using a modified base plate, longer central post and augmentation with cancellous bone graft harvested from the patients humeral head. Objectives. This study aims to compare the outcome in terms of analgesic effect, function and satisfaction, in patients treated with standard RSA and BIO-RSA. Methods. All cases were performed in a single centre by one of two upper limb consultant orthopaedic surgeons over a consecutive 2-year period. At time of listing for operation, the decision as to whether to undertake a bony-increased offset reverse total shoulder was made. Standard deltopectoral approach was performed. Standard and Bony increased offset Tournier reverse was the implant of choice (BIO-RSA). All patients underwent a standardised rehabilitation programme. Standard follow up was clinical review with radiographs at 2 weeks, 6weeks and 3months. Retrospective data was collected using case notes on patient reported stausfaction and oxford shoulder score, analgesia requirement at final follow up, and final range of movement. Results. A total of 60 patients (65 shoulders) were treated with reverse total shoulder replacements (RSA) within a 2-year period in a single centre for chronic complex shoulder conditions. Mean age at time of intervention was 74.1years (49.3 – 88.7). Mean follow up was 7.1 months (3.4 – 24). Average time to discharge 16.1 months (3.4 – 37.4). 43 patients currently under review. Of the 65 shoulders, 40 underwent BIO-RSA procedures. Indications for surgery were predominantly rotator cuff arthropathy (N=36). Other indications included severe osteoarthritis (N=1) and complex proximal humeral fracture (N=3). The remaining 25 patients treated with standard RSA were similar in terms of indication and basic demographics. In terms of range of movement, outcomes between the two groups were broadly similar. Patients receiving BIO-RSA demonstrated mean active forward flexion of 92.2° (70–120°) and abduction 93.3° (80–120°). The RSA group had mean forward flexion 90.5° (50–130°) and mean abduction 88.6° (40–160°). Both groups had excellent analgesic effect with 92% in each either being completely pain free or requiring only occasional analgesia. The majority of patients were either very satisfied or satisfied with the outcome of the surgery. Mean Oxford shoulder score for the BIO-RSA group was 4.9 (0–13) preoperatively and 43.7 (36–48) postoperatively. The mean RSA pre-operative score was 7.9 (0–19) and postoperatively 40.2(32–48). In total three patients experienced complications; 1 haematoma (BIO-RSA), 1 brachial plexus contusion (BIO-RSA) and 1 deep infection (RSA). Conclusion. If grafting is necessary, the use of BIO-RSA within this centre seems to have comparable results to those undergoing standard RSA. Early results also suggest the Bio-RSA allows earlier improvement and conserves a larger bone stock. These early result are encouraging however a further study with longer follow-up is required

Introduction. Reverse total shoulder replacement is performed for the treatment of rotator cuff arthropathy, massive irreparable cuff tears and failed shoulder hemiarthroplasty with irreparable rotator cuff tears. The aim of this study was to assess the clinical and radiological outcome of single surgeon series of Equinoxe® reverse total shoulder replacement at a district general hospital. Materials/Methods. Consecutive patients who underwent Equinoxe® reverse total shoulder replacement at our unit from Jun 2008 to Dec 2010 were retrospectively reviewed. Indications for surgery, complications and radiological outcomes were assessed. Oxford shoulder score was used to assess the functional outcome. Results. Between Jun 2008 and Dec 2012, forty-one reverse total shoulder replacements were performed by the senior author in 37 patients. Of these, Equinoxe® prostheses were used in 27 operations (26 patients). These included 22 female and 4 male patients. Cuff arthropathy was the commonest preoperative diagnosis (23 patients), followed by proximal humeral fracture non-union (2 patients), failed hemiarthroplasty (one patient) and failed resurfacing (one patient). The mean follow up was 10 months (3 to 17 months). At the time of the study, three patients had died due to unrelated causes, two were not contactable and the remaining 21 patients were analysed. The mean oxford shoulder score was 35.8 (21–48). Nineteen patients (90.5%) graded their outcome a good to excellent while 2 patients (9.5%) graded as poor. Seventeen patients (81%) expressed that they would recommend this operation. One patient (4.7%) had infection and another had dislocation. Overall, there were 3 reoperations (14.3%); first washout, second change of humeral tray and third excision of lateral end of clavicle and reattachment of deltoid. Two patients (9.5%) had small glenoid notching. There was no loosening, neurovascular injury or postoperative haematoma. Conclusion. Early outcome of Equinoxe reverse shoulder replacement is promising. Longer follow-up is required to further assess the outcome

Aims. The aim of this study was to analyse human muscle tissue before and after rotator cuff repair to look for evidence of regeneration, and to characterise the changes seen in the type of muscle fibre. Patients and Methods. Patients were assessed pre-operatively and one year post-operatively using the Oxford Shoulder Score (OSS) and MRI. The cross-sectional area and distribution of the type of muscle fibre were assessed on biopsies, which were taken at surgery and one year post-operatively. Paired samples from eight patients were analysed. There were three men and five women with a mean age of 63 years (50 to 73). Results. All but one patient showed improvement in OSS (p = 0.004). The mean increase in the cross-sectional area of the muscle was 1220 μm. 2. (-801 to 3712; p = 0.03). There was a reduction of type 2a fibres (p = 0.02). A clear relationship could not be seen between the MRI findings and the histological appearances. Conclusion. This is the first study to provide evidence that atrophy of the supraspinatus muscle is reversible. Changes in the types of fibre are discussed. MRI assessment of muscle atrophy may not be fully representative of myofibre atrophy. Cite this article: Bone Joint J 2016;98-B:1389–94

Purpose. The evolution of locked anatomical clavicular plating in combination with evidence to suggest that fixation of clavicle fractures yields better outcome to conservative treatments has led to an increasing trend towards operative management. There is no evidence however to compare early fixation with delayed reconstruction for symptomatic non- or mal-union. We hypothesize that early intervention yields better functional results to delayed fixation. Methods. Between August 2006 and May 2010, 97 patients were managed with operative fixation for their clavicular fracture. Sixty eight with initial fixation and 29 delayed fixation for clavicular non- or mal-union. Patients were prospectively followed up to radiographic union, and outcomes were measured with the Oxford Shoulder Score, QuickDASH, EQ5D and a patient interview. Mean follow-up was to 30 months. All patients were managed with Acumed anatomical clavicular plates. Results. The radiographic and clinical outcomes were available for all patients. Scores were available for 62 (62/97). There were no statistically significant differences in age (p>0.05), sex (p>0.05), energy of injury (p>0.05), number of open fractures (p>0.05) between the two groups. The mean quickDASH was 8.9 early, 9.1 delayed (p< 0.05), Oxford Shoulder score was 15.7 early, 16.1 delayed (p< 0.05). In the early fixation group 5 patients had wound healing complications, and 8 went on subsequently to have removal of prominent metalwork. In the delayed fixation group 2 had wound healing complications and 4 had removal of prominent metalwork. There were no statistically significant differences in the EQ5D quality of life questionnaire. Conclusion. There are no statistically significant differences in shoulder performance, wound or operative complications between early and delayed fixation of clavicular fractures. Our series does not support early fixation of clavicular fractures, as results for delayed intervention in those who become symptomatic appear comparable

Introduction: Clavicle fractures represent 5% of fractures in adults and almost 44% of shoulder injuries and are usually treated none operatively with good results. However significantly displaced fractures can be associated with high non-union rate and there is a lack of consensus on when surgical treatment is indicated for such fractures. The aim of this study was to identify guidelines for surgical intervention, safer surgical approach and outcome of surgical intervention. Method: A retrospective audit of all clavicle fractures managed surgically over past 5 years (March 2004 to 2009) in a district general hospital. Case notes were reviewed to study the surgical indication, surgical approach, patient satisfaction and oxford should score and need for metal work removal. In all 35 patients (29 male) underwent surgery for significant fracture displacement with shortening, manual workers and keen sportsmen at the time of injury. The infraclavicular approach was used in 21 patients and 14 patients had direct incision approach. Radiological union was achieved in all patients after an average of 13.26(8–24) weeks. Six patients required plate removal at 6 months following surgery, infraclavicular (2 patients) & direct approach (4 patients). All patients returned to their original occupation at average 2.55 months. The Oxford Shoulder Score at 3 months after surgery was average 15 (range12–20) and all patients, except one, scored excellent on subjective scoring. Conclusion: Our study showed excellent surgical outcome for displaced clavicle fractures in young and active patients and is supported by the high union rate, good oxford shoulder score, early return to work and high patient satisfaction scores. The infraclaviculr approach is a betterthan direct approach based on the low complication rate and less need for metal work removal

Large and massive rotator cuff tears can cause persistent pain and significant disability. These tears are often chronic with substantial degeneration of the involved tendons. Surgical treatment is challenging and the functional outcome after repair less predictable then for smaller tears. The aim of this study was to determine the functional outcome and rate of re-rupture after mini-open repair of symptomatic large and massive rotator cuff tears using a modified two-row technique. Twenty-four patients, who were operated on under the care of a single surgeon between 2003 and 2006, were included in this study. Patients were assessed prospectively before and at a mean of 27 months after surgery using Constant Score and Oxford Shoulder Score. This assessment was carried out by an independent physiotherapist specialising in shoulder rehabilitation. At follow-up an ultrasound was carried out by a musculoskeletal radiographer to determine the integrity of the rotator cuff repair. Patient satisfaction was assessed using a simple questionnaire. The mean Constant Score improved significantly from 36 preoperatively to 68 postoperatively (p< 0.0001), the mean Oxford Shoulder Score from 39 to 20 (p< 0.0001). Four patients (16.7%) had a re-rupture diagnosed by ultrasound. 87.5% of patients were satisfied with the outcome of their surgery. Tear size and repair integrity did not significantly influence functional outcome. 87.5% of patients were satisfied or very satisfied with the outcome of their surgery. This study shows that the two-row repair of large and massive rotator cuff tears using a mini-open approach is an effective method of repair with a comparatively low re-rupture rate. It significantly improves the functional outcome and leads to a very high patient satisfaction. We conclude that these results justify repair of large to massive rotator cuff tears when possible, irrespective of chronicity of symptoms

The function of the shoulder joint has traditionally been evaluated based on range of motion (ROM) in predefined anatomical planes and also by using functional scores, which assessed shoulder function based on the ability to conduct certain activities of daily living (ADLs). However, measuring ROM only in terms of flexion-extension, abduction-adduction and internal-external rotation may under-account for the 3-dimensional mobility of the shoulder joint. Furthermore, functional scores, such as the Oxford shoulder score or American shoulder and elbow surgeons (ASES) score, are subjective measures and are not an accurate assessment of shoulder joint function. In this study, we proposed the use of the globe model of the shoulder joint which can be used to provide an objective measure of the global ROM and also function of the shoulder joint – termed the Global and Functional arc of motion (GAM and FAM). Thirty-three young, healthy male patients (23.7 ± 1.5 years) were recruited and tasked to perform eight ADLs and a full humeral circumduction movement which represented their active global ROM. Reflective markers were placed in accordance to the International Society of Biomechanics (ISB) and optical-based motion capture cameras were used to track relative motion of the dominant humerus with respect to the thorax (i.e. thoracohumeral motion). The GAM and FAM were generated by plotting the thoracohumeral on a spherical coordinate system during global ROM and the eight ADLs respectively. Shoulder joint global ROM and function were quantified by calculating the area enclosed by the closed loop of GAM and FAM respectively. The spherical coordinate system, or more commonly referred to as the globe model, describes thoracohumeral movement using plane of elevation (POE), angle of elevation (AOE) and rotation. In our model, POE and AOE represents longitude and latitude of the globe respectively, and rotation is depicted using a red-green-blue (RGB) colour scale. Overall, subject's GAM of the shoulder joint covered an area of 4.64 ± 0.48 units2 compared to only 1.12 ± 0.26 units2 for the FAM. Subjects only required 24.4 ± 5.7 % of their global shoulder ROM for basic daily functioning. Studies that reduced shoulder joint movement into planar movements (i.e. sagittal, coronal and rotation) do not account for the 3-dimensional nature of the joint and doing so may overestimate the requirement of the shoulder joint for ADLs relative to its ROM in each plane. While others have attempted to use the globe model, such studies tend to reduce the globe into its descriptive angles (i.e. POE, AOE and rotation), reducing its intuitiveness. In contrast, by keeping an intact globe, the proposed globe model was more intuitive and yet capable of quantifying both shoulder joint global ROM and function. Doing so, we found that young healthy subjects only required approximately a quarter of their global ROM of the shoulder joint to complete the most common daily tasks, which was significantly less than what was previously reported

Aim. We present the medium-term clinical results of a reverse total shoulder arthroplasty with a trabecular metal glenoid base plate. Patients and Methods. We reviewed 125 consecutive primary reverse total shoulder arthroplasties (RTSA) implanted in 124 patients for rotator cuff arthropathy. There were 100 women and 24 men in the study group with a mean age of 76 years (58 to 89). The mean follow-up was 32 months (24 to 60). No patient was lost to follow-up. Results. There were statistically significant improvements in the mean range of movement and Oxford Shoulder Score (p < 0.001). Kaplan-Meier survivorship at five years was 96.7% (95% confidence interval 91.5 to 98.7) with aseptic glenoid failure as the end point. . Radiologically, 63 shoulders (50.4%) showed no evidence of notching, 51 (40.8%) had grade 1 notching, ten (8.0%) had grade 2 notching and one (0.8%) had grade 4 notching. Radiolucency around the glenoid base plate was found in one patient (0.8%) and around the humeral stem in five (4.0%). In all, three RTSA (2.4%) underwent revision surgery for aseptic mechanical failure of the glenoid within 11 months of surgery due to malseating of the glenosphere. Conclusion. The clinical results of this large independent single unit series are comparable to those from previous series of RTSA reported in the literature. A trabecular metal base plate is safe and effective in the medium-term. Cite this article: Bone Joint J 2016;98-B:969–75

Background: The incidence of proximal humeral fractures is increasing with time. There is continuing debate about the indications for surgical intervention for this relatively common injury. Baseline data on functional outcome is essential in order to study the effect of surgical intervention. Functional outcome scores provide reliable and valid judgments of health status and the benefits of treatment. During our preparation of a study proposal on this topic to the Health Technology Assessment Program recently, we noted the lack of such data on outcome scores in the current literature. Aim: To assess the functional outcome using the Constant and Oxford scores in patients treated conservatively for proximal humeral fractures. Methods: We prospectively studied 103 consecutive patients who were treated conservatively for proximal humeral fractures. Patient demographics, fracture type (Neer), hand dominance and comorbidity were recorded. Constant and Oxford shoulder scores were recorded 3 and 12 months post injury. Results: The average Constant shoulder score for males was significantly higher (better outcome) and the Oxford shoulder score significantly lower (better outcome) as compared to females. The scores were not affected by hand dominance. Although the raw scores tended to be worse with 3 or 4 part fractures the difference in the mean scores between the various Neer fracture types did not reach convential levels of significance. A trend towards lesser degrees of improvement in the outcome scores was noted with increasing age. The degree of improvement in the outcome scores was not affected by sex, limb dominance or fracture type (Neer’s classification). Conclusion: This study indicates the average behaviour of the Constant and Oxford scores with conservative treatment of proximal humeral fractures. This data should help with sample size and power calculations when studying interventions for this injury. We hope that this data will provide a baseline to help inform future study designs on proximal humeral fractures

Impingement syndrome in the shoulder has generally been considered to be a clinical condition of mechanical origin. However, anomalies exist between the pathology in the subacromial space and the degree of pain experienced. These may be explained by variations in the processing of nociceptive inputs between different patients. We investigated the evidence for augmented pain transmission (central sensitisation) in patients with impingement, and the relationship between pre-operative central sensitisation and the outcomes following arthroscopic subacromial decompression. We recruited 17 patients with unilateral impingement of the shoulder and 17 age- and gender-matched controls, all of whom underwent quantitative sensory testing to detect thresholds for mechanical stimuli, distinctions between sharp and blunt punctate stimuli, and heat pain. Additionally Oxford shoulder scores to assess pain and function, and PainDETECT questionnaires to identify ‘neuropathic’ and referred symptoms were completed. Patients completed these questionnaires pre-operatively and three months post-operatively. A significant proportion of patients awaiting subacromial decompression had referred pain radiating down the arm and had significant hyperalgesia to punctate stimulus of the skin compared with controls (unpaired t-test, p < 0.0001). These are felt to represent peripheral manifestations of augmented central pain processing (central sensitisation). The presence of either hyperalgesia or referred pain pre-operatively resulted in a significantly worse outcome from decompression three months after surgery (unpaired t-test, p = 0.04 and p = 0.005, respectively). These observations confirm the presence of central sensitisation in a proportion of patients with shoulder pain associated with impingement. Also, if patients had relatively high levels of central sensitisation pre-operatively, as indicated by higher levels of punctate hyperalgesia and/or referred pain, the outcome three months after subacromial decompression was significantly worse

We have carried out a prospective double-blind randomised controlled trial to compare the efficacy of a single subacromial injection of the non-steroidal anti-inflammatory drug, tenoxicam, with a single injection of methylprednisolone in patients with subacromial impingement. A total of 58 patients were randomly allocated into two groups. Group A received 40 mg of methylprednisolone and group B 20 mg of tenoxicam as a subacromial injection along with lignocaine. The Constant-Murley shoulder score was used as the primary outcome measure and the Disability of Arm, Shoulder and Hand (DASH) and the Oxford Shoulder Score (OSS) as secondary measures. Six weeks after injection the improvement in the Constant-Murley score was significantly greater in the methylprednisolone group (p = 0.003) than in the tenoxicam group. The improvement in the DASH score was greater in the steroid group and the difference was statistically significant and consistent two (p < 0.01), four (p < 0.01) and six weeks (p < 0.020) after the injection. The improvement in the OSS was consistently greater in the steroid group than in the tenoxicam group. Although the difference was statistically significant at two (p < 0.001) and four (p = 0.003) weeks after the injection, it was not at six weeks (p = 0.055). Subacromial injection of tenoxicam does not offer an equivalent outcome to subacromial injection of corticosteroid at six weeks. Corticosteroid is significantly better than tenoxicam for improving shoulder function in tendonitis of the rotator cuff after six weeks

If a modular convertible total shoulder system is used as a primary implant for an anatomical total shoulder arthroplasty, failure of the prosthesis or the rotator cuff can be addressed by converting it to a reverse shoulder arthroplasty (RSA), with retention of the humeral stem and glenoid baseplate. This has the potential to reduce morbidity and improve the results. . In a retrospective study of 14 patients (15 shoulders) with a mean age of 70 years (47 to 83) we reviewed the clinical and radiological outcome of converting an anatomical shoulder arthroplasty (ASA) to a RSA using a convertible prosthetic system (SMR system, Lima, San Daniele, Italy). . The mean operating time was 64 minutes (45 to 75). All humeral stems and glenoid baseplates were found to be well-fixed and could be retained. There were no intra-operative or early post-operative complications and no post-operative infection. The mean follow-up was 43 months (21 to 83), by which time the mean visual analogue scale for pain had decreased from 8 pre-operatively to 1, the mean American Shoulder and Elbow Surgeons Score from 12 to 76, the mean Oxford shoulder score from 3 to 39, the mean Western Ontario Osteoarthritis of the Shoulder Score from 1618 to 418 and the mean Subjective shoulder value from 15 to 61. On radiological review, one patient had a lucency around the humeral stem, two had stress shielding. There were no fatigue fractures of the acromion but four cases of grade 1 scapular notching. . The use of a convertible prosthetic system to revise a failed ASA reduces morbidity and minimises the rate of complications. The mid-term clinical and radiological results of this technique are promising. Cite this article: Bone Joint J 2015;97-B:1662–7

Objectives: The aim of this study was a clinical and radiological evaluation of 68 shoulders operated with the Delta reverse-ball-and-socket total shoulder prosthesis by the senior author with a mean follow-up of 42 months. Methods: This is a retrospective study in one consecutive series of 68 shoulders, operated by the senior author, which were clinically assessed using the Constant score for pain, Constant Shoulder Score, Oxford Shoulder Score, UCLA Shoulder rating scale, DASH Score, Rowe Score for Instability and Oxford Instability Score. Radiological evaluation was graded by the classification according to Nerot et al. and complications were analysed according to Goslings and Gouma. Patients were evaluated before surgery and at a mean clinical follow-up of 42 months. Results: There was a significant improvement in all clinical and stability scores. On the average, the Constant score for pain increased from 4.62 to 11.08 points (p< 0.05); the Constant Shoulder Score from 32.65 to 60.31 (p> 0.05); the Oxford Shoulder Score increased from 32.65 to 60.31 (p< 0.05) and the UCLA Shoulder rating scale increased from 15.08 to 27.42 (p< 0.05). The evaluation of stability showed an increase from 49.42 to 80.19 points in the Rowe Score for Instability and from 22.04 to 37.62 in the Oxford Instability score (p< 0.05). According to the Nerot classification, 65 percent of patients were graded as “0”, 20 percent as “1”, 3 percent as “2”, 6 percent as “3” and 6 percent as “4”. Eight complications occurred in terms of a nerve lesion which was graded according to Goslings and Gouma as “1” once, loosening of the humeral stem which was graded as “2” three times and loosening or fracture of the glenoid component which was graded as “2” in five times. At mean follow-up of 42 months, one patient of this series had died of decrepitude which was graded as “4” and one patient was lost of follow-up. Conclusions: We summarize, that there were significant advantages identified in terms of the Constant score for pain, all clinical scores and the instability scores. Radiological analyses showed 85 percent of patients without or with a small notch only. On the other hand, the rate of complications should be taken into account. We conclude that shoulder arthroplasty with the Delta prosthesis shows significant benefits in terms of less shoulder pain, a higher stability and a gain of range of motion but on the other hand, we emphasize that this treatment remains a salvage procedure in the elderly only

We have compared the outcome of hemiarthroplasty of the shoulder in three distinct diagnostic groups, using survival analysis as used by the United Kingdom national joint registers, patient-reported outcome measures (PROMs) as recommended by Darzi in the 2008 NHS review, and transition and satisfaction questions. A total of 72 hemiarthroplasties, 19 for primary osteoarthritis (OA) with an intact rotator cuff, 22 for OA with a torn rotator cuff, and 31 for rheumatoid arthritis (RA), were followed up for between three and eight years. All the patients survived, with no revisions or dislocations and no significant radiological evidence of loosening. The mean new Oxford shoulder score (minimum/worst 0, maximum/best 48) improved significantly for all groups (p < 0.001), in the OA group with an intact rotator cuff from 21.4 to 38.8 (effect size 2.9), in the OA group with a torn rotator cuff from 13.3 to 27.2 (effect size 2.1) and in the RA group from 13.7 to 28.0 (effect size 3.1). By this assessment, and for the survival analysis, there was no significant difference between the groups. However, when ratings using the patient satisfaction questions were analysed, eight (29.6%) of the RA group were ‘disappointed’, compared with one (9.1%) of the OA group with cuff intact and one (7.7%) of the OA group with cuff torn. All patients in the OA group with cuff torn indicated that they would undergo the operation again, compared to ten (90.9%) in the OA group with cuff intact and 20 (76.9%) in the RA group. The use of revision rates alone does not fully represent outcome after hemiarthroplasty of the shoulder. Data from PROMs provides more information about change in pain and the ability to undertake activities and perform tasks. The additional use of satisfaction ratings shows that both the rates of revision surgery and PROMs need careful interpretation in the context of patient expectations

Aim: To study the long term results of rotator cuff repair in patients over the age of 65. Introduction: Although some patients with rotator cuff tears are asymptomatic, the majority have a combination of pain, weakness and restricted function. Whilst this affects the lifestyle of all patients, in the elderly these symptoms can make the difference between independent living and the need for assistance or sheltered accommodation. Method: The present study has looked at a consecutive series of 24 patients all of them over 65 years, who underwent rotator cuff surgery between 1993 and 1997. Outcome has been assessed using two validated scoring systems – the Oxford Shoulder Score (OSS) and the DASH questionnaire. All patients had an open subacromial decompression of their shoulders at the time of cuff repair. Two patients could not be contacted for follow up and were therefore excluded. One patient who had a hemiarthroplasty of the shoulder 3 years after rotator cuff repair was excluded as well. The average follow up period was 6 years (range 4.5 – 9 years). The Oxford Shoulder Score revealed that 72% had good to excellent results, 16% remained unchanged and 12% were worse than prior to surgery. The corresponding DASH scores were 28% excellent, 40% good, 16% fair and 16% poor respectively. In addition 81% of patients were independent with daily activities, with 48% of them living alone and the remaining 33% living with their partners. Only 19% of patients needed significant help with their activities of daily living. These results were irrespective of whether surgery was performed on the dominant or non-dominant shoulder. Conclusion: We would suggest that age itself should not be considered a contraindication to rotator cuff repair

The treatment of massive chronic tears is problematic. The re-tear rate following surgery for extensive cuff tears remains high, and there is little consensus regarding optimum treatment. To investigate the outcome of a cohort of patients who had open repair of an extensive cuff tear using the Leeds Kuff patch as an augment. A retrospective cohort study of consecutive patients with a massive cuff tear who had surgery in our regional elective orthopaedic centre over a two year period from January 2015 to Dec 2016. All patients followed identical rehabilitation protocols, supervised by physiotherapists with an interest in the shoulder. Outcomes assessment was undertaken at a minimum of 12 months by a registrar or physiotherapist who was not part of the treating team. Pre-op data collection included; range of motion, pain score, Oxford shoulder score (OSS), assessment of muscle atrophy on MRI. Data collection was completed in 15 patients. The mean age was 62 yrs (56 – 75). The mean pre-op OSS was 22, improving to a mean of 43. The range of motion and pain score improved. There were no intra-operative complications. One patient required a second surgery for evacuation of a haematoma at 10 days post op. One patient had an obvious re-tear at 4 months. Open rotator cuff repair with synthetic Kuff patch augmentation for chronic degenerative tears appears worthwhile when assessed at 12 months and they continuous to improve even at 18 months. This treatment method may be a useful option for patients > 70 years old

The aim of this study was to investigate genetic influences on the development and progression of tears of the rotator cuff. From a group of siblings of patients with a tear of the rotator cuff and of controls studied five years earlier, we determined the prevalence of tears of the rotator cuff with and without associated symptoms using ultrasound and the Oxford Shoulder Score. In the five years since the previous assessment, three of 62 (4.8%) of the sibling group and one of the 68 (1.5%) controls had undergone shoulder surgery. These subjects were excluded from the follow-up. Full-thickness tears were found in 39 of 62 (62.9%) siblings and in 15 of 68 (22.1%) controls (p = 0.0001). The relative risk of full-thickness tears in siblings as opposed to controls was 2.85 (95% confidence interval (CI) 1.75 to 4.64), compared to 2.42 (95% CI 1.77 to 3.31) five years earlier. Full-thickness tears associated with pain were found in 30 of 39 (76.9%) tears in the siblings and in eight of 15 (53.3%) tears in the controls (p = 0.045). The relative risk of pain associated with a full-thickness tear in the siblings as opposed to the controls was 1.44 (95% CI 2.04 to 8.28) (p = 0.045). In the siblings group ten of 62 (16.1%) had progressed in terms of tear size or development compared to one of 68 (1.5%) in the control group which had increased in size. Full-thickness rotator cuff tears in siblings are significantly more likely to progress over a period of five years than in a control population. This implies that genetic factors have a role, not only in the development but also in the progression of full-thickness tears of the rotator cuff

A total of 92 patients with symptoms for over six months due to subacromial impingement of the shoulder, who were being treated with physiotherapy, were included in this study. While continuing with physiotherapy they waited a further six months for surgery. They were divided into three groups based on the following four clinical and radiological criteria: temporary benefit following steroid injection, pain in the mid-arc of abduction, a consistently positive Hawkins test and radiological evidence of impingement. Group A fulfilled all four criteria, group B three criteria and group C two criteria. A total of nine patients improved while waiting for surgery and were excluded, leaving 83 who underwent arthroscopic subacromial decompression (SAD). The new Oxford shoulder score was recorded pre-operatively and at three and 12 months post-operatively. A total of 51 patients (group A) had a significant improvement in the mean shoulder score from 18 (13 to 22) pre-operatively to 38 (35 to 42) at three months (p < 0.001). The mean score in this group was significantly better than in group B (21 patients) and C (11 patients) at this time. At one year patients in all groups showed improvement in scores, but patients in group A had a higher mean score (p = 0.01). At one year patients in groups A and B did better than those in group C (p = 0.01). Arthroscopic SAD is a beneficial intervention in selected patients. The four criteria could help identify patients in whom it is likely to be most effective

Osteolysis has been reported following ACJ reconstruction with a synthetic graft. We present the first study into its prevalence and pattern, and its effect on patient outcome. Patients who underwent treatment of an unstable ACJ injury using the Surgilig/LockDown implant were identified via our database. Patients were invited to attend a dedicated outpatient clinic for clinical examination, radiographic evaluation, and completion of outcome scoring. Patients who were unable to attend were contacted by telephone. 49 patients were identified. We assessed 21 clinically at a mean of 7 years post-procedure (range 3–11 years). All had radiographic evidence of distal clavicle and coracoid osteolysis. We did not observe progression of osteolysis from the final post-operative radiographs. A further 13 were contacted by phone. The mean Oxford Shoulder Score was 43 (range 31–48) and mean DASH score was 8.5 (range 3–71). The average Patient Global Impression of Change score was 6 (range 2–7). Six patients underwent removal of a prominent screw at a mean of 2 years after surgery; the pattern of osteolysis was no different in this group. All patients had comparable abduction, forward flexion and internal rotation to their uninjured shoulder. We did not observe any relationship between patient demographics, position of implant or etiology and the pattern of osteolysis. Osteolysis of the distal clavicle and/or coracoid is always seen following synthetic reconstruction of the ACJ using this implant, but is non-progressive. Range of shoulder movement is largely unaffected and patient outcomes remain high

The combination of an irreparable tear of the rotator cuff and destructive arthritis of the shoulder joint may cause severe pain, disability and loss of independence in the aged. Standard anatomical shoulder replacements depend on a functioning rotator cuff, and hence may fail in the presence of tears in the cuff. Many designs of non-anatomical constrained or semi-constrained prostheses have been developed for cuff tear arthropathy, but have proved unsatisfactory and were abandoned. The DePuy Delta III reverse prosthesis, designed by Grammont, medialises and stabilises the centre of rotation of the shoulder joint and has shown early promise. This study evaluated the mid-term clinical and radiological results of this arthroplasty in a consecutive series of 50 shoulders in 43 patients with a painful pseudoparalysis due to an irreparable cuff tear and destructive arthritis, performed over a period of seven years by a single surgeon. A follow-up of 98% was achieved, with a mean duration of 39 months (8 to 81). The mean age of the patients at the time of surgery was 81 years (59 to 95). The female to male ratio was 5:1. During the seven years, six patients died of natural causes. The clinical outcome was assessed using the American Shoulder and Elbow score, the Oxford Shoulder Score and the Short-form 36 score. A radiological review was performed using the Sirveaux score for scapular notching. The mean American Shoulder and Elbow score was 19 (95% confidence interval (CI) 14 to 23) pre-operatively, and 65 (95% CI 48 to 82) (paired t-test, p < 0.001) at final follow-up. The mean Oxford score was 44 (95% CI 40 to 51) pre-operatively and 23 (95% CI 18 to 28) (paired t-test, p < 0.001) at final follow-up. The mean maximum elevation improved from 55° pre-operatively to 105° at final follow-up. There were seven complications during the whole series, although only four patients required further surgery

The shoulder is the least constrained of all joints of the body and is more susceptible to injury including dislocation. The rate of recurrent instability following primary stabilization procedure at 10 years of follow-up ranged from 3.4 to 35 %. We describe the outcomes of 74 patients who underwent knotless arthroscopic anterior stabilisation using 1.5 mm Labral Tape with 2.9mm Pushlock anchors for primary anterior instability. We performed a retrospective analysis of patients who underwent surgery for post-traumatic recurrent anterior instability for 2 years by a single surgeon. Patients with glenoid bone loss, >25% Hill Sachs lesion, posterior dislocation, paediatric age group and multidirectional instability were excluded from this study. Over 90% of our case mix underwent the procedure under regional block anaesthesia and was discharged on the same day. The surgical technique and post-operative physiotherapy was as per standard protocol. Outcomes were measured at 6 months and 12 months. Of the 74 patients in our study, we lost 5 patients to follow up. Outcomes were measured using the Oxford Shoulder Score apart from clinical assessment including the range of motion. We noted good to excellent outcomes in 66 cases using the Oxford Instability Scores. All patients achieved almost full range of motion at the end of one year. Our cumulative Oxford Instability Score (OIS) preoperatively was 24.72 and postoperatively was 43.09. The Pearson correlation was .28. The t Critical two-tail was 2.07 observing the difference between the means of the OIS. Complications included recurrent dislocation in 2 patients following re-injury and failure of procedure due to recurrent instability requiring an open bone block procedure in one case. We had no reported failures due to knot slippage or anchor pull-out. We publish the largest case series using this implant with distinct advantages of combining a small bio absorbable implant with flat braided, and high-strength polyethylene tape to diminish the concern for knot migration and abrasive chondral injury with the potential for earlier rehabilitation and a wider footprint of labral compression with comparative outcomes using standard techniques. Our results demonstrate comparable and superior results to conventional suture knot techniques for labral stabilization

Background. Functional outcomes of conservatively managed, valgus impacted proximal humeral fractures are poor. Operative fixation can improve results but can be technically challenging. We prospectively assessed outcomes following fixation of valgus unstable proximal humeral fractures with a novel hybrid fixed angle blade plate, at a minimum of 12 months follow up. Methods. A new hybrid fixed angle blade plate design (Fx Plate, Exactech, Gainesville, USA) was used by the senior author to treat patients with displaced and potentially valgus unstable proximal humeral fractures, at our institution between November 2012 and March 2014. The study was approved by the research and development department. Outcomes were prospectively assessed using the Oxford and Constant shoulder scores and quality of life was assessed using the SF-36 questionnaire. Radiographs were taken at regular intervals to assess fracture healing. Results. In total 12 patients were identified and included in the study. All patients had comminution of the medial calcar, with potentially valgus unstable fracture patterns. Six of the patients had two-part displaced fractures, whereas six had three and four-part fractures. One patient died for reasons unrelated to surgery and three others were lost to follow up. Average follow up after surgery was 15.4 months (Range 12–20 months). At final follow up the average Oxford Shoulder Score was 41 (35 to 48) and Constant Score 73 (60 to 87), indicating a good functional outcome of the operated side. The average physical and mental component scores of the SF-36 questionnaire were 49 and 52 respectively, suggesting a good overall quality of life. Radiographs, taken at final follow up, confirmed fracture union in all cases. No significant complications occurred following surgery. Conclusions. Patients with displaced, potentially valgus unstable, proximal humeral fractures remain a challenging cohort to treat. Our results, however, indicate good functional and radiographic outcomes when using a novel hybrid fixed angle blade plate

We present 2 year results of a prospective natural history study of Type III Acromioclaviclular joint dislocation (ACJD) treated non-operatively. Previous natural history studies are compromised by inconsistent definitions of the grade of injury and non-validated scoring tools; they do not identify which patients will have ongoing symptoms. This trial documents the strength and subjective recovery over time, and identifies risk factors for poor outcome and need for surgery. Patients with Rockwood Type III ACJD received a standardised rehabilitation protocol (6 sessions of physiotherapy). Clinical assessment was performed at presentation, 3, 6, 12 and 24 months after injury, including isometric strength testing, pain (VAS/10) and subjective scores – Subjective percentage of normal (SPON), American Shoulder and Elbow (ASES), Oxford Shoulder Score (OSS) and Quick Disabilities of Arm Shoulder and Hand (qDASH). 28 male patients were recruited, 26 reached 12, and 9 to 24 months follow up. Two required surgery and one emigrated. The mean age was 39 (15 to 67). Initial mean pain was 3/10, SPON 51% (6–95) and strength was 76% of the other side. By 3 months mean subjective recovery was 70% and strength 90%. Strength recovered to 99% of normal by 12 months but subjective scores remained at mean 90%; by 24 months subjective scores were mean 94%. 2 patients had subjective scores <80%. There was a wide range of initial subjective scores and weakness after Type III ACJD. 95% of strength had recovered by 6 months and subjective scores recovered to 94% of normal by 24 months. 4 patients (14%) did poorly with 2 requiring surgery. Low initial subjective score and inability to abduct the arm at presentation were risk factors for a poor outcome

Pain is a common presenting symptom of patients with shoulder conditions, yet there has been little work done to accurately describe its distribution and nature. We studied all patients attending the Royal Devon and Exeter Hospital shoulder clinic from August 2012 – 2013. Patients completed a questionnaire detailing their Oxford Shoulder Score and a validated neuropathic pain questionnaire. Patients were given diagrams to draw on their perceived location of pain or abnormal sensation. We analysed all patients with frozen shoulder (48), osteoarthritis (37) and rotator cuff arthropathy (17). We found that neuropathic pain is common in patients with shoulder conditions identified in 39% of OA patients, 42% with rotator cuff arthropathy and 57% with frozen shoulder. Pain outside the shoulder was reported in over 50% of patients, commonly the forearm, hand, neck and chest. Frozen shoulder was especially associated with pain outside of the shoulder with 39% describing symptoms in the neck or chest, 21% into the forearm and 18% into the hand. Interestingly, neuropathic pain radiating down the arm was not described in the rotator cuff arthropathy group. The high prevalence of neuropathic symptoms and pain felt outside the shoulder aids diagnosis and more accurately identifies these conditions

Introduction. The new era of shoulder arthroplasty is moving away from long stemmed, cemented humeral components to cementless, stemless and metaphyseal fixed implants and to humeral resurfacing. The early clinical results and functional outcome of stemless shoulder arthroplasty is presented. Methods. A retrospective single-surgeon series of stemless shoulder prostheses implanted from 2011 to 2013 at our institution was evaluated. Perioperative complications, Theatre time and length of hospital stay (LOS) were recorded. Postoperative radiographic and clinical evaluation including measurement of joint mobility, the Oxford Shoulder Score (OSS), and Disabilities of the Arm, Shoulder and Hand (DASH) score by independent evaluators were made. Results. A total of 23 stemless shoulder arthroplasty were implanted in 22 patients. Mean age was 57.8 years. Mean follow up was 22 months (8–45). Symptomatic primary gleno-humeral osteoarthritis was the main indication for implantation (83%). None of the patients experienced periprosthetic fractures, glenoid notching, and implant loosening/migration. Mean OSS (44 ± 6.0) and mean DASH score (11 ± 6.5). Mean operative time was (88 ± 16.0 min) and mean length of hospital stay (1.1 ± 0.82 day). Active shoulder motion improved by (mean): 30° (95% CI 10–45) external rotation, 67° (95% CI 30- 100) forward elevation and 54° (95% CI 35- 90) Abduction. Conclusion. The implantation of stemless shoulder prosthesis in our institution offered good clinical results manifested by improved range of motion and favourable patient reported outcome measures. Although long term follow up is warranted, early results appear promising in young patients with symptomatic gleno-humeral osteoarthritis

Clavicular hook plates have been used over the last decade in the treatment of lateral clavicular fractures with good rates of union reported throughout the literature. Fewer studies have reported the functional outcome of these patients and some have reported potential soft tissue damage post plate removal. We aimed to review the functional outcomes alongside union rates in patients treated with hook plates for lateral clavicular fractures. In this retrospective case series, 21 patients with traumatic lateral third clavicular fractures were included. 15 had Neer type II fractures, 4 Neer type III fractures, 1 patient had a Neer type I fracture and 1 radiograph was not able to be classified. All patients were treated with clavicular hook plates at the same district general hospital by five experienced surgeons between March 2010 and February 2015 adhering to the same surgical protocol. All patients had standard physiotherapy and post operative follow up. Plates were removed when radiological union was achieved in all but one patient who had the plate removed before union was achieved due to prolonged non-union. Patients were followed up post plate removal and evaluated clinically using the Oxford Shoulder Score. Their post plate radiographs were assessed by an independent radiologist and bony union documented. 21 patients were included. Mean age was 40 (range 14–63) with a male:female ratio of 17:4. Mean follow up was 5 months post injury (1–26 months). The hook plate remained in situ for a mean time of 4.3 months (2–16 months). One patient developed a post-operative wound infection treated with antibiotics, 2 patients developed adhesive capsulitis, one patient had not achieved bony union prior to hook plate removal at 16 months, however did achieve union 2 months post plate removal, two patients required revision plating. All patients achieved bony union eventually with good alignment and no displacement of the acromioclavicular joint seen on the most recent post operative radiographs. Post plate removal Oxford Shoulder Scores indicated good shoulder function with a mean score of 41.5 (maximum score possible 48 and the range of scores for our cohort was 30–47). Our data would support the use of hook plates in the treatment of lateral clavicular fractures. All patients achieved union eventually with good alignment and this was reflected in the good functional outcome scores. This study is limited in its small cohort and short-term follow up. More research is required to examine the long term consequences of hook plate surgery in a larger patient population

Introduction. Hypoplasia of the glenoid is a rare condition caused by incomplete ossification of the postero-inferior aspect of the developing glenoid. It may be isolated or associated with a more generalised condition. The clinical symptomatology is variable depending on the age at time of presentation. Materials and Methods. We performed a retrospective chart review of patients who presented with shoulder complaints, and in whom a radiographic diagnosis of glenoid hypoplasia had been made. From January 2002 to December 2012, 8 patients (9 shoulders) with radiological signs of glenoid hypoplasia were identified. The mean age at presentation was 39 years (range 23 to 77) and the mean symptom duration was 12.5 months (range 1 to 48). Results. The diagnoses encountered included: impingement with rotator cuff tendonitis (2 shoulders), rotator cuff dysfunction with biceps tendonitis (1 shoulder), a SLAP lesion (2 shoulders), calcific tendonitis (1 shoulder), a posterior labral tear (1shoulder), multidirectional instability (1 shoulder), and adhesive capsulitis (1 shoulder). Of these nine, six shoulders were managed non-operatively and three were managed surgically, all with satisfactory results. The mean follow-up period was 30 months (range 5 to 60) and the mean Oxford shoulder score was 46.7 (range 42 to 48). Conclusion. We present a series of patients, who have been managed for a variety of shoulder pathologies, and in whom underlying glenoid hypoplasia has been diagnosed. NO DISCLOSURES

The Global Conservative Anatomic Prosthesis (Global CAP) is an uncemented press fit humeral resurfacing implant developed by DePuy. We report a single surgeon series of Global CAP prostheses implanted in Norwich. 103 procedures were carried out between 2006 and 2011, in 93 patients. Mean age was 72 years (range 43 to 90). Patients were followed up for a mean 8 months (range 0 to 56). Pre-operative Oxford shoulder scores were recorded in a preadmission clinic and an Oxford score questionnaire was sent to patients post-operatively in December 2011. The mean score preoperatively was 19, rising to 28 postoperatively. Two patients developed rotator cuff tears and have been revised to reverse polarity arthroplasty. One is pending revision for a cuff tear. This prosthesis shows promise at this early stage for compensated glenohumeral arthritis when a bone preserving procedure is desirable

We evaluated the long-term survival and patient reported outcome of the Copeland mark III humeral resurfacing hemi-arthroplasty (Biomet, Warsaw, Indiana). At a UK District General Hospital 95 shoulder replacements in 85 patients were performed from 1994 to 2003 (mean age 68.9). At the time of follow-up (mean of 12 years, range 8.7–18.0) 49 patients had survived. This study group were posted Oxford Shoulder Score (OSS) and SF-12 questionnaires and their case notes were reviewed. There was an 82% response rate. The responders comprised 46 shoulders in 40 patients. 40 shoulders had a pre-operative diagnosis of osteoarthritis and 6 had other pathologies. The median OSS was 36. The median functional score was 24 (IQR: 9.5), where 32 is the best. The median pain score was 13 (IQR: 7) with 16 being the best score. There was a median SF 12 score of 31 (IQR: 3), where the maximum score is 47. There were 3 revision operations and 95% survivorship at 18 years, according to Kaplan Meier survival analysis. The Copeland mark III hemi-arthroplasty prosthesis has a good long term survival, few post-operative complications and a good functional outcome in an elderly population. We would advocate its use in this patient group

Management of irreparable rotator cuff tears is challenging and controversial. Surgeons have been utilising biological tissue scaffolding to augment repairs, but there are concerns regarding viability and function. We wished to investigate this viability and clinical outcome in a small group of patients. All procedures were performed by a single surgeon over a three-year period. Inclusion criteria were patients with large cuff tears and failure of non-operative treatment. Exclusion criteria were patients with glenohumeral arthritis and where cuff repair could not be successfully performed. Open rotator cuff repair followed by augmentation with Graft Jacket® Regenerative Tissue Matrix (Wright Medical) was performed in all patients. A structured cuff repair physiotherapy protocol was then followed. Follow-up was at six months and at minimum twenty-four months post-operatively where Constant scores (CS) and Oxford Shoulder scores (OSS) were noted and a repeat ultrasound performed. Fourteen patients underwent the procedure. No patient was lost to follow-up. There were seven males and seven females with a mean age of 63 years (range 31–77). At minimum twenty-four month follow-up, thirteen patients had flexion and abduction above 90 degrees and symmetrical external rotation. Mean CS was 81 (range 70–91) and mean OSS was 46 (range 41–48). Shoulder ultrasound revealed an intact Graft Jacket® in all thirteen patients. The final patient had lower functional movement and lower CS (34) and OSS (25) and ultrasound identified a re-rupture. This study indicates that augmentation of large rotator cuff repairs with biological tissue scaffolding is a viable option and has good functional results

Aims

The primary aim of this study was to assess the feasibility of recruiting and retaining patients to a patient-blinded randomized controlled trial comparing corticosteroid injection (CSI) to autologous protein solution (APS) injection for the treatment of subacromial shoulder pain in a community care setting. The study focused on recruitment rates and retention of participants throughout, and collected data on the interventions’ safety and efficacy.

Manipulation under anaesthetic (MUA) is an established treatment for frozen shoulder. Frozen shoulder may coexist with other shoulder conditions, whose treatment may differ from MUA. One such condition is calcific tendonitis. Only one study to date documents treatment of patients with frozen shoulder and concurrent calcific tendinitis. The objective was to demonstrate that MUA and injection is a satisfactory treatment for concurrent diagnosis of frozen shoulder and calcific tendinitis. Patients with a clinical diagnosis of frozen shoulder and radiological evidence of calcific tendinitis were prospectively recruited from Jan 1999 – Jan 2009. Treatment by MUA and injection was performed. Clinical examination, Oxford Shoulder Scores and need for further treatment were used as outcome measures. Fourteen patients (median age 53.5 years) were identified with frozen shoulder and concurrent calcific tendinitis. Significant improvement in both Oxford Shoulder Score and range of movement was achieved following MUA (P values < 0.001). Two patients required further treatment (not for calcific tendinitis). This improvement was maintained in the long term (median 107 wks). It is our belief that MUA and injection is a safe and effective treatment, addressing the frozen shoulder with MUA takes priority, and as such frozen shoulder “trumps” other pathologies occurring simultaneously

Eighty-eight consecutive patients with symptomatic rotator cuff tears were entered in to a prospect study with a novel technique of open double row repair using a ‘Capstan’ screw technique. The medial row has standard anchors, but the lateral suture row is a 35mm × 6.5mm ‘Capstan' screw. This allows up to 28 suture bridges to be taken from the medial row to the lateral row compressing the footprint and spreading the load. This creates a very robust repair or ‘bulletproof repair’. This was used for medium to large isolated supraspinatus tears. Each patient had a pre and post operative Oxford Shoulder Score (OSS), American Shoulder and Elbow Score (ASES Score). The mean pre-operative OSS was 22 (maximum 48) and the mean post-operative OSS was 45, (p < 0.0001). Flexion improved from a mean of 117° to 172° (p < 0.0001). The clinical re-tear rate was 3.4%. 95% were satisfied with the procedure. There were no deep infections. 18% had transient stiffness, 6% stiffness at one year but none severe enough to warrant release. There were no instances of deltoid dysfunction. This demonstrates excellent results in terms of OSS, patient satisfaction and function. Clinical re-tear rate is markedly reduced in comparison to previous literature

Distension arthrography of the glenohumeral joint was adopted as a mainstream treatment for adhesive capsulitis before any randomised controlled trials were performed. Interpretation of the effectiveness of this procedure rests on data from cohort studies of which there are few of high quality. Papers reporting on the long-term results have either excluded diabetic patients or failed to report on patient orientated outcomes. We present a prospective cohort study of 51 patients with adhesive capsulitis of the shoulder who had a distension arthrogram performed by a single radiologist as a primary intervention. We included diabetic patients. Range of movement (ROM), Oxford shoulder score (OSS) and a visual analogue pain score (VAS) were recorded pre-procedure, at 2 days and 1 month. OSS and VAS were recorded again at a mean of 14 months post procedure (range 8–26 months). OSS improved from pre-procedure mean of 22.3 by 16.9 points at final follow up in September 2011 (p < 0.001) whilst VAS improved from a mean pre-procedure of 7.1 by −3.5 by September 2011 (p< 0.001). ROM improved with a mean increase of 39.3 degrees in flexion, 55.2 degrees in abduction and 19.5 degrees in external rotation by 1 month (p < 0.001 for all). The outcome in diabetic patients was the same as in non-diabetic patients. We conclude that distension arthrography is a safe and effective treatment for adhesive capsulitis

We undertook a prospective randomised trial to determine the outcome of locked intramedullary fixation vs. plating of displaced shortened mid-shaft clavicle fractures. The primary outcome measure was the Constant shoulder score, while secondary outcome measures included the Oxford shoulder score, union rate, and complication rates. Thirty-two patients were recruited to the trial; 17 randomised to locked intramedullary fixation and 15 randomised to plating. Mean age was 29.3years (13 to 53 years). Mean follow-up was 12.4 months (5 to 28 months). There was no significant difference in Constant scores (p = 0.365) and no significant difference in Oxford scores (p = 0.686). There was 100% union in both groups. In the intramedullary group, there was one case of soft tissue irritation that settled after the pin was removed, one pin backed out and had to be revised with another pin. There were three superficial wound infections resulting in plate removal and 8 plates (53%) were removed. Locked intramedullary fixation and plating are equally effective in the management of shortened displaced mid-shaft clavicle fractures

Frozen shoulder is a common condition that affects the working population. The longevity and severity of symptoms often results in great economic burden to health services and absence from work. This prospective cohort study aimed to investigate whether early intervention with arthroscopic capsular release resulted in improvement of symptoms and any potential economic benefit to society. Patients were recruited prospectively. Data was gathered by way of questionnaire to ascertain demographics, previous primary care treatment and absence from work. Oxford Shoulder Score (OSS) was also calculated. Arthroscopic capsular release was performed and further data gathered at four week post-operative follow up. Economic impact of delay to treatment and cost of intervention was calculated using government data from the national tariff which costs different forms of treatment. Statistical analysis was then performed on the results. Twenty five patients enrolled. Mean pre-operative OSS: 37.4 (range 27–58, SD 7.4). Mean post-operative OSS: 15.9 (range 12–22, SD 2.3). P<0.01. Mean improvement in OSS: 21.5 (range 12–38, SD 7.1). The cost of non-operative treatment per patient was £3954. The cost of arthroscopic capsular release per patient was £1861, a difference of £2093. There were no complications. Arthroscopic capsular release improved shoulder function on OSS within four weeks. The cost of arthroscopic capsular release is significantly less than the cost of treating the patients non-operatively. Early surgical intervention may improve symptoms quickly and reduce economic burden of the disease. A randomised controlled trial comparing timings of intervention would further elucidate potential benefits

Introduction. Massive rotator cuff tears in the patient who is too young for a reverse shoulder replacement are a challenging situation. A technique using a ‘Grammont osteotomy’ of the acromion has been developed to allow a comprehensive approach, the so called “Full Monty”. Aim. To document the functional outcome of patients undergoing an acromial osteotomy for the repair of massive tears of the supraspinatus. Methods. Ten patients undergoing this procedure where entered in to the study. The mean age of the patients was 57 years (+/−16) and all bar one were male. Each patient had a pre-operative American Shoulder Elbow Score (ASES), Oxford Shoulder score (OSS), and range of movement documented. These outcome measures were repeated at a minimum of two years, as well as a patient satisfaction questionnaire. Results. The mean ASES preoperatively was 7(+/− 6) and 23(+/−3) post-operatively (p< 0.001). The mean pre-operative OSS was 22(+/−5) and 43(+/−4) post-operatively (p<0.001). 80% of patients deemed their treatment to be “successful” and 90% would recommend the procedure to a friend in the same plight. The mean post-operative forward flexion achieved was 153° (+/−58) and the mean abduction was 142° (+/−37). All patients could sustain a 1kg weight at arms length at 90° of abduction. One patient suffered a superficial wound infection and one patient had a non-union at the osteotomy site. Conclusion. These results suggest that this technique is a good surgical option for a patient with a “massive” rotator cuff tear that is not amenable to standard surgical techniques

Malformation and hypoplasia of the clavicle can result in pain, impaired function, restricted shoulder movement, subjective feeling of instability and cosmetic deformity. There are no reports of clavicle lengthening by osteotomy and distraction osteogenesis (DO). This is a retrospective review of 5 patients (7 clavicles) who underwent clavicle lengthening by DO using a monolateral external fixator for clavicular hypoplasia. There were 3 males and 2 females with mean age 15 years (9 to 23) and mean follow-up 21 months (8 to 51). Preoperative diagnoses included Klippel-Feil syndrome, cleidocranial dysplasia with torticollis, congenital myopathy and Noonans syndrome and obstetric brachial plexus injury. Mean length gained was 31 mm (15 to 41) which represens an average of 24.7% of overall bone length. Mean time in fixator was 174 days (161 to 263) and mean external fixation index was 56 days/cm. Two patients required internal fixation following fixator removal to consolidate union and one required additional internal fixation for atrophic regenerate. Mean preoperative oxford shoulder score improved from 28.5 to 41 and all patients were extremely satisfied with their result. Two patients developed pin site infections. Clavicular lengthening by distraction osteogenesis for congenital clavicular hypoplasia is a previously unreported technique that enables gradual correction of deformity without risking brachial plexus traction injury following acute correction. It has the potential to improve shoulder pain, function, range of movement and cosmesis. Distraction ≥25% of overall bone length may require additional plate fixation to consolidate union

Arthritis of the glenohumeral joint accompanied by an irreparable tear of the rotator cuff can cause severe pain, disability and loss of function, particularly in the elderly population. Anatomical shoulder arthroplasty requires a functioning rotator cuff, however, reverse shoulder arthroplasty is capable of addressing both rotator cuff disorders and glenohumeral deficiencies. The Aequalis Reversed Shoulder Prosthesis design is based on two bio-mechanical principles by Grammont; a medialized center of rotation located inside the glenoid bone surface and second, a 155 degree angle of inclination. Combined, they increase the deltoid lever arm by distalizing the humerus and make the prosthesis inherently stable. 24 consecutive primary reverse total shoulder arthroplasties were performed by a single surgeon for arthritis with rotator cuff compromise and 1 as a revision for a failed primary total shoulder replacement between December 2009 and October 2012. Patients were assessed postoperatively with the use of the DASH score, Oxford shoulder score, range of shoulder motion and plain radiography with Sirveaux score for scapular notching. Mean age at the time of surgery was 72.5 years (range 59 to 86). Average follow up time was 19.4 months (range 4 to 38). Functional outcome scores from our series were comparable with patients from other follow up studies of similar prosthesis design. All patients showed improvement in range of shoulder movement postoperatively. Complications included one dislocation, one acromion fracture and one humeral shaft fracture. No cases of deep infection were recorded. Overall, the short-term clinical results were promising for this series of patients and indicate reverse shoulder arthroplasty as an appropriate treatment for this group of patients

Reverse total shoulder arthroplasty (RTSA) provides a surgical alternative to conventional shoulder arthroplasty in the rotator cuff deficient shoulder. Short term data has shown consistent improvements in pain and function but higher complication and failure rates have also been reported. The aims of this study were to identify the early and late complications of RTSA, to establish the frequency of glenoid notching, and to assess the post-operative functional outcomes. 21 patients (22 joints) treated with RTSA at Glasgow Royal Infirmary (GRI) between April 2006 and October 2010 were retrospectively reviewed. Indications for surgery included cuff tear arthropathy, revision hemiarthroplasty and fracture malunion. Complication rates were obtained by analysis of follow up data from Bluespier and case notes. Glenoid notching was graded from x-rays by multiple observers using the Sirveaux classification. Outcome was assessed using the Oxford Shoulder Score (OSS) and range of motion (ROM). The complication rate associated with RTSA was 14.3%, effecting 3 patients. One dislocation and 1 ulnar nerve palsy occurred within 30 days post-op. A late complication was represented by 1 dislocation, which required revision. Glenoid notching occurred in 71.4% (15 of 21patients), though the majority had a low Sirveaux classification (grade 1 or 2). OSS increased post-operatively and showed a linear improvement with time (R. 2. = 0.81) and ROM increased significantly post-op compared with pre-op (p<0.001). The complication rate associated with RTSA at GRI was lower than that reported in literature and the outcome was good as defined by ROM and OSS. The rate of glenoid notching was higher than literature reports but the significance of this is unclear as notching may not be associated with loosening

Purpose:. We aimed to assess the short and medium term complications of patients who had undergone Latarjet procedures. We also compared this to a group of patients who over a similar period underwent an open Bankhart procedure to assess the complication profiles between the two groups. Method:. We retrospectively reviewed the notes and X-rays of all patients identified by surgical log books and or operation codes for instability. Eighty seven patients (88 shoulders) underwent Latarjet procedures between 2002 and 2010. Patients were phoned to obtain a telephonic Oxford shoulder score. There were 44 patients with 46 shoulders in the open Bankhart group. Results:. Complications were seen in 27 patients in the Latarjet group. These included: 5 nerve injuries (3 axillary nerves, 1 musculocutaneous nerve, 1 possible suprascapular nerve) 4 of which resolved; 6 screw related complications and 7 early recurrences of the instability. There was a total reoperation rate of 8%. Patients who developed complications had an average post op Oxford score at last follow up of 36.1, while those without complications had an average score of 14.8. In the group of patients who underwent Bankhart procedures there were no recorded short or medium term complications. We specifically did not look at recurrence rates in either group as we felt our follow up times would not reflect this adequately. Conclusion:. Modified Latarjet procedure appears to have a higher short and medium term complication rate compared to the open Bankhart procedure. Once a complication occurs following a Latarjet reconstruction outcomes are significantly worse

Manipulation under anaesthetic (MUA) for the treatment of frozen shoulder is well established and effective however timing of surgery remains controversial. Intervention before 9 months has previously been shown to be associated with improved outcome. We test this theory by measuring Oxford Shoulder Score (OSS), re-MUA and subsequent surgery rate. A retrospective review of a prospectively collected, single surgeon, consecutive patient series revealed 244 primary frozen shoulders treated by MUA within 4 weeks of presentation. The mean duration of antecedent symptoms was 28 weeks (95% CI 4-44 weeks) and time to follow up was 26 days (95% CI 11-41 days). The mean OSS improved by 16 points (2-tailed t test p< 0.001) with a mean follow up OSS of 43 (95% CI 38-48). 195 shoulders were manipulated before 38 weeks (9 months) and had the same mean change in OSS (16) as the 49 shoulders manipulated after 38 weeks. 48 shoulders, including 15 diabetic shoulders required further MUA. 8 shoulders had subsequent surgery. These events were also independent of antecedent symptom duration. Early MUA does not appear to produce improved outcomes when compared to later intervention but we note does result in an earlier return to function

The effect of timing of a manipulation under anaesthetic (MUA) and injection of corticosteroid and local anaesthetic for the treatment of frozen shoulder has attracted little attention to date. All studies describe a period of conservative treatment before proceeding to an MUA. Delay has been associated with a poorer outcome. We present a retrospective review of a prospectively collected, single-surgeon, consecutive series of 246 patients with a primary frozen shoulder treated by MUA within four weeks of presentation. The mean duration of presenting symptoms was 28 weeks (6 to 156), and time to initial post-operative assessment was 26 days (5 to 126). The Oxford shoulder score (OSS) improved by a mean of 16 points (Wilcoxon signed-ranks test, p < 0.001) with a mean OSS at this time of 43 (7 to 48). Linear regression analysis showed no correlation between the duration of presenting symptoms and OSS at initial follow-up (R2 < 0.001) or peri-operative change in OSS (R2 < 0.001) or OSS at long-term follow-up (R2 < 0.03). Further analysis at a mean of 42 months (8 to 127) revealed a sustained improvement with a mean OSS of 44 (16 to 48). A good outcome follows an MUA and injection of corticosteroid and local anaesthetic in patients with primary frozen shoulder, independent of the duration of the presenting symptoms, and this improvement is maintained in the long term

Background. Frozen Shoulder is a common condition which causes significant morbidity in people of working age. The 2 most popular forms of surgical treatment for this condition are Manipulation under Anaesthesia (MUA) or MUA plus Arthroscopic Capsular Release (ACR). Both treatment modalities are known to give good results, but no-one has compared the two to see which is better. Aim. To compare the outcome in patients with primary frozen shoulder, who are treated by either MUA or MUA plus ACR. Methods. 56 patients with primary frozen shoulder were treated by either MUA or MUA plus ACR. Each patient had their American Shoulder and Elbow Score (ASES), and their Oxford Shoulder Score (OSS) measured pre- and post-operatively. Results. The patients who had MUA plus ACR had a mean ASES of 19.6 pre-operatively, 78.3 at 6 months, and a mean of 80.1 at 12 months. The mean OSS was 32.5 pre-operatively, 53.6 at 6 months and 53.8 at 12 months. The patients who had a MUA had a mean ASES of 28.7 pre-operatively, 57.9 at 6 months and 58 at 12 months. The mean OSS was 33 pre-operatively, 42.5 at 6 months and 48 at 12 months. Conclusions. Both treatments give good results; MUA plus ACR give significantly superior results at 6 to 12 months post-operatively. However, there is no significant difference beyond 12 months

Introduction. Whiplash injury following rear shunt Road traffic accident (RTA) has been associated with impingement syndrome of shoulder. However, the results of arthroscopic subacromial decompression (ASAD) for this group of patients have never been compared to the non accident group. In our study we aim to compare the results of ASAD in these patients to a group who did not sustain whiplash injury. Materials/Methods. Thirteen patients with impingement syndrome following rear shunt RTA were followed up (2004–09). After failed conservative management for at least 6 months ASAD was performed. This group was compared with a control group (not involved in an RTA) of 13 consecutive patients (age and sex matched). All patients were assessed with Oxford shoulder score preoperatively and twice post operatively (within 3 months and at one year). Results. In the RTA group all 13 patients showed improvement in their oxford score over one year. While the improvement was only Marginal (p= 0.08) at three months it was better at the end of a year (p=0.04). Comparatively in the cohort without the whiplash injury the improvement was more marked in the first three months (p=0.05) with significant improvement at the end of the year (p=0.03). The overall improvement in Oxford score was more in the cohort of patients who were not involved in a RTA as opposed to the RTA group (p= 0.05). Conclusion. The results of the study show that even though there was an improvement in shoulder scores after an arthroscopic subacromial decompression it was much slower and overall results were inferior in the RTA group as opposed to the controls and hence prognosis should be guarded when offering ASAD for patients with whiplash injury

We report a retrospective review of outcome after shoulder hemiarthroplasty for proximal humerus fractures. All patients managed with shoulder hemiarthroplasty for proximal humerus fractures between 1997 and 2008 were included. Clinical notes were reviewed and surviving patients completed postal Oxford Shoulder Score (OSS) questionnaires. Results were analysed to assess whether there was a difference in outcome for those above the age of 70 years. A total of 96 patients were treated during this period. Female to male ratio was 3.36:1 with mean age 72 ± 9.6 (45–93) years at time of fracture. At time of review 30.2% of patients were dead. Two patients were lost to follow-up after discharge. Complete case notes were available in 68 patients. Response rate to the OSS was 67.2%. There were 20 patients below 70 years and 48 patients above 70 years of age. The ASA grade was II in 60% of patients. Mean follow-up was 52 months. There were 2 in hospital post-operative deaths due to medical complications. Mean OSS was 27 (3–47) of a maximum of 48, with no significant difference between groups. Overall complication rate was 27.9%, with no significant difference between groups. Ten year survival was 96.9% overall with no significant difference between groups. There appears to be no significant difference in functional outcome, complication rate, or implant survival between patients below or above the age of 70 years treated with primary hemiarthroplasty for fracture of the proximal humerus. This procedure however carries a high complication rate in this group of patients

Scapulothoracic fusion (STF) for painful winging of the scapula in neuromuscular disorders can provide effective pain relief and functional improvement, but there is little information comparing outcomes between patients with dystrophic and non-dystrophic conditions. We performed a retrospective review of 42 STFs in 34 patients with dystrophic and non-dystrophic conditions using a multifilament trans-scapular, subcostal cable technique supported by a dorsal one-third semi-tubular plate. There were 16 males and 18 females with a mean age of 30 years (15 to 75) and a mean follow-up of 5.0 years (2.0 to 10.6). The mean Oxford shoulder score improved from 20 (4 to 39) to 31 (4 to 48). Patients with non-dystrophic conditions had lower overall functional scores but achieved greater improvements following STF. The mean active forward elevation increased from 59° (20° to 90°) to 97° (30° to 150°), and abduction from 51° (10° to 90°) to 83° (30° to 130°) with a greater range of movement achieved in the dystrophic group. Revision fusion for nonunion was undertaken in five patients at a mean time of 17 months (7 to 31) and two required revision for fracture. There were three pneumothoraces, two rib fractures, three pleural effusions and six nonunions. The main risk factors for nonunion were smoking, age and previous shoulder girdle surgery. STF is a salvage procedure that can provide good patient satisfaction in 82% of patients with both dystrophic and non-dystrophic pathologies, but there was a relatively high failure rate (26%) when poor outcomes were analysed. Overall function was better in patients with dystrophic conditions which correlated with better range of movement; however, patients with non-dystrophic conditions achieved greater functional improvement
