Abstract. Reverse shoulder arthroplasty (RSA) is being increasingly used for complex, displaced fractures of the proximal humerus. The main goal of the current study was to evaluate the functional and radiographic results after primary RSA of three or four-part fractures of the proximal humerus in elderly patients. Between 2012 and 2020, 70 consecutive patients with a recent three- or four-part fracture of the proximal humerus were treated with an RSA. There were 41 women and 29 men, with a mean age of 76 years. The dominant arm was involved in 42 patients (60%). All surgeries were carried out within 21 days. Displaced three-part fracture sustained in 16 patients, 24 had fracture dislocation and 30 sustained a four-part fracture of the proximal humerus. Patients were followed up for a mean of 26 months. The mean postoperative OSS at the end of the follow-up period was 32.4. The mean DASH score was 44.3. Tuberosity non-union occurred in 18 patients (12.6%), malunion in 7 patients (4.9%), heterotopic ossification in 4 patients (2.8%) and scapular notching in one patient. Anatomical reconstruction was achieved in 25 patients (17.5%), the influence of greater tuberosity healing on shoulder function could not be demonstrated. Heterotopic ossification seems to affect OSS and QDASH, we found statistically significant relation between HO and clinical outcomes. Patients with heterotopic ossification had significantly lower postoperative scores on DASH and OSS (P = .0527). Despite expecting good functional outcome with low complication rate after RSA, the functional outcome was irrespective of healing of the tuberosities

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 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.

Glenoid bone grafting in reverse total shoulder arthroplasty (RTSA) has emerged as an effective method of restoring bone stock in the presence of complex glenoid bone loss, yet there is limited published evidence on efficacy. The aim of this study was to conduct an analysis of clinical and radiographic outcomes associated with glenoid bone grafting in primary RTSA. Patients who underwent a primary RTSA with glenoid bone grafting were retrospectively identified from the databases of two senior shoulder surgeons. Inclusion criteria included minimum of 12 months clinical and/or radiographical follow up. Patients underwent preoperative clinical and radiographic assessment. Graft characteristics (source, type, preparation), range of movement (ROM), patient-reported outcome measures (Oxford Shoulder Scores [OSS]), and complications were recorded. Radiographic imaging was used to analyse implant stability, graft incorporation, and notching by two independent reviewers. Between 2013 and 2021, a total of 53 primary RTSA procedures (48 patients) with glenoid bone grafting were identified. Humeral head autograft was used in 51 (96%) of cases. Femoral head allograft was utilised in two cases. Depending on the morphology of glenoid bone loss, a combination of structural (corticocancellous) and non-structural (cancellous) grafts were used to restore glenoid bone stock and the joint line. All grafts were incorporated at review. The mean post-operative OSS was significantly higher than the pre-operative OSS (40 vs. 22, p < 0.001). ROM was significantly improved post-operatively. One patient is being investigated for residual activity-related shoulder pain. This patient also experienced scapular notching resulting in the fracturing of the inferior screw. One patient experienced recurrent dislocations but was not revised. Overall, at short term follow up, glenoid bone grafting was effective in addressing glenoid bone loss with excellent functional and clinical outcomes when used for complex bone loss in primary RTSA. The graft incorporation rate was high, with an associated low complication rate

Introduction. The purpose of this study was to compare implant survivorship and functional outcomes in patients undergoing reverse total shoulder arthroplasty (RTSA) for acute proximal humeral fracture (PHF) with those undergoing elective RTSA in a population-based cohort study. Methods. Prospectively collected data from the New Zealand Joint Registry from 1999 to 2021 and identified 7,277 patients who underwent RTSA. Patients were categorized by pre-operative indication, including acute PHF (10.1%), rotator cuff arthropathy (RCA) (41.9%), osteoarthritis (OA) (32.2%), rheumatoid arthritis (RA) (5.2%) and old traumatic sequelae (4.9%). The PHF group was compared with elective indications based on patient, implant, and operative characteristics, as well as post-operative outcomes (Oxford Shoulder Score [OSS], and revision rate) at 6 months, 5 and 10 years after surgery. Survival and functional outcome analyses were adjusted by age, sex, ASA class and surgeon experience. Results. Implant survivorship at 10 years for RTSA for PHF was 97.3%, compared to 96.1%, 93.7%, 92.8% and 91.3% for OA, RCA, RA and traumatic sequelae, respectively. When compared with RTSA for PHF, the adjusted risk of revision was higher for traumatic sequelae (hazard ratio = 2.29; 95% CI:1.12–4.68, p=0.02) but not for other elective indications. At 6 months post-surgery, OSS were significantly lower for the PHF group compared to RCA, OA and RA groups (31.1±0.5 vs. 35.6±0.22, 37.7±0.25, 36.5±0.6, respectively, p<0.01), but not traumatic sequelae (31.7±0.7, p=0.43). At 5 years, OSS were only significantly lower for PHF compared to OA (37.4±0.9 vs 41.0±0.5, p<0.01), and at 10 years, there were no differences between groups. Discussion and Conclusion. RTSA for PHF demonstrated reliable long-term survivorship and functional outcomes compared to other elective indications. Despite lower functional outcomes in the early post-operative period for the acute PHF group, implant survivorship rates were similar to patients undergoing elective RTSA

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

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

This paper presents an ongoing review of the use of a wedge-shaped porous metal augments in the shoulder to address glenoid retroversion as part of anatomical total shoulder arthroplasty (aTSA). Seventy-five shoulders in 66 patients (23 women and 43 men, aged 42 to 85 years) with Walch grade B2 or C glenoids underwent porous metal glenoid augment (PMGA) insertion as part of aTSA. Patients received either a 15º or 30º PMGA wedge (secured by screws to the native glenoid) to correct excessive glenoid retroversion before a standard glenoid component was implanted using bone cement. Neither patient-specific guides nor navigation were used. Patients were prospectively assessed using shoulder functional assessments (Oxford Shoulder Score [OSS], American Shoulder and Elbow Standardized Shoulder Assessment Form [ASES], visual analogue scale [VAS] pain scores and forward elevation [FE]) preoperatively, at three, six, and 12 months, and yearly thereafter, with similar radiological surveillance. Forty-nine consecutive series shoulders had a follow-up of greater than 24 months, with a median follow-up of 48 months (range: 24–87 months). Median outcome scores improved for OSS (21 to 44), ASES (24 to 92), VAS (7 to 0), and FE (90º to 140º). Four patients died, but no others were lost to follow-up. Apart from one infection at 18 months postoperatively and one minor peg perforation, there were no complications, hardware failures, implant displacements, significant lucency or posterior re-subluxations. Radiographs showed good incorporation of the wedge augment with correction of glenoid retroversion from median 22º (13º to 46º) to 4º. All but four glenoids were corrected to within the target range (less than 10º retroversion). The porous metal wedge-shaped augments effectively addressed posterior glenoid deficiency as part of aTSA for rotator cuff intact osteoarthritis, producing satisfactory clinical outcomes with no signs of impending future failure

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

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. The conservative management of Sub-Acromial Impingement Syndrome (SAIS) of the shoulder includes both physiotherapy treatment and subacromial injection with local anaesthetic and steroids. The outcome from injection treatment has rarely been evaluated scientifically. Methods. Patients attending a designated shoulder clinic and diagnosed by an experienced shoulder surgeon as having a SAIS between January 2009 and December 2011 were considered for inclusion in the study. 67 of 86 patients screened completed the study (3 did not meet inclusion criteria; 9 declined to participate; 3 lost to follow-up; 4 developed frozen shoulder syndrome). Each patient had a pre-injection Oxford Shoulder Score (OSS) and was given one subacromial injection of 10ml 0.25% levobupivacaine(Chirocaine) + 40 mg triamcinolone(Kenalog) through the posterior route. Radiograph imaging was also assessed. Follow-up was carried out at 6 to 12 weeks post injection when OSS was repeated. A 6 month follow-up assessment to assess if the patient's improvement in functionality and absence of symptoms indicated that a subacromial decompression operation was not necessary. The percentage of patients showing improvement in OSS was calculated and the difference in OSS pre- and post-injection assessed using a Wilcoxon Signed Rank test. Results. The median OSS pre-injection was 29 (range 2–43) and post-injection was 40 (range 2–48) (p=< 0.001; z=−6.0; r=−0.5). 45/69 (71%) of patients benefited significantly from subacromial injection at 6 to 12 weeks post-injection. However only 28/53 (53%) benefited significantly from injection by 6 months post-injection. These results support the continued use of sub-acromial corticosteroid injections in the treatment of SAIS. 31% of these patients were subsequently treated with an arthroscopic subacromial decompression operation. Previous injection history had no impact on the results. Conclusions. We recommend that all patients with SAIS should be offered at least one subacromial injection before being considered for an arthroscopic subacromial decompression operation

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

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

Introduction. The Constant Score (CS) and the Oxford Shoulder Score (OSS) are shoulder scoring systems routinely used in the UK. Patients with Acromio-Clavicular Joint (ACJ) and Sterno-Clavicular Joint (SCJ) injuries and those with clavicle fractures tend to be younger and more active than those with other shoulder pathologies. While the CS takes into account the recreational outcomes for such patients the weighting is very small. We developed the Nottingham Clavicle Score (NCS) specifically for this group of patients. Methods. We recruited 70 patients into a cohort study in which pre-operative and 6 month post-operative evaluations of outcome were reviewed using the CS, the OSS the Imatani Score (IS) and the EQ-5D scores which were compared with the NCS. Reliability was assessed using Cronbach's alpha. Reproducibility of the NCS was assessed using the test/re-test method. Each of the 10 items of the NCS was evaluated for their sensitivity and contribution to the total score of 100. Validity was examined by correlations between the NCS and the CS, OSS, IS and EQ-5D scores pre-operatively and post-operatively. Results. Significant correlations were demonstrated post-operatively between the NCS and OSS (p< 0.001), CS (p=0.001), IS (p< 0.001) and the ‘self-care’ (p=0.013), ‘pain’ (p< 0.001) and ‘usual activities’ (p< 0.001) sub-categories of EQ-5D. Internal consistency was excellent (Cronbach's alpha=0.87). Removal of an item measuring cosmetic satisfaction improved the alpha to 0.90. Significant agreement was found on test/re-test examination. Differences in NCS were directly related to differences in all 4 comparative outcome measures and 91% of patients with improved post-op NCS values reported improvements in their symptoms. Conclusions. The NCS has been proven to be a valid, reliable and sensitive outcome measure that can accurately measure the level of function and disability in the joint, SC joint and clavicle. We recommend its future use for clinical evaluation

Introduction. Health Economists in Denmark have recently reported low and delayed return to work for patients treated for Sub-Acromial Impingement syndrome (SAIS) by Arthroscopic Sub-Acromial Decompression (ASAD). Surgeons however are reporting that patients achieve good pain relief and a high standard of activities of daily living (ADL) after surgery. Aim. To evaluate the effectiveness of ASAD for patients with SAIS and correlate clinical outcome with rate of return to work. Methods. Prospective cohort study and retrospective review of data from the Nottingham Shoulder database (presentation: 01/04/2008–30/06/2011). Inclusion criteria: Patients diagnosed clinically with SAIS by an experienced shoulder surgeon, who have failed conservative treatment (physiotherapy and sub-acromial injection), undergoing ASAD. Pre-operative and 6-month follow-up Oxford Shoulder Score (OSS) and Constant Score (CS) were compared. The rates of return to pre-operative level of work were also analysed. Statistical analysis: Wilcoxon signed rank test. Results. 73 patients with OSS (51 also with CS documentation) were included. The improvement in median OSS between pre-operative (24) and 6-month follow-up (39) was +15 (Z = −6.726, ∗∗∗, T=6, r=0.55). The difference in median CS between pre-operative (39) and 6-month follow-up (67) was +28 (Z=−5.435, T=6, r=0.59, ∗∗∗). Improvement in median pain score was +5 (7,12, ∗∗∗) median ADL was +5.5 (10.5,16, ∗∗∗) median ROM was +13 (18,31, ∗∗∗) and median strength was +4 (3,7, ∗∗∗). 76% returned to their pre-operative level of work (mean time = 11.5 weeks post surgery). 79% returned to their pre-operative hobbies (mean time = 11.8 weeks post surgery). Conclusion. There is a significant improvement in OSS and CS, 6 months after ASAD in patients with SAIS who have had previous failed conservative treatment. The rate of return to work was good for these patients in contrast to that reported for Danish patients. (∗∗∗ = p< 0.0001 = Highly statistically significant)

Background. The Copeland shoulder resurfacing arthroplasty (CSRA) (Figure1) is a cementless, pegged humeral head surface replacement which has been in clinical use since 1986. The indications for CSRA are more or less the same as conventional stemmed arthroplasty. This procedure can be considered for all patients who require shoulder replacement due to GHJ arthritis resulted from primary or secondary OA, RA, and other variations of inflammatory arthritis. It is also suggested as the first choice option for relatively young patients with post-traumatic arthritis, avascular necrosis (AVN), and instability arthropathy. This observational study reports functional and radiological outcome in CSRA during 4 years follow-up. Methods. 109 consecutive patients with primary osteoarthritis (45.9%), rheumatoid arthritis (39.4%), rotator cuff arthropathy (9.2%), and avascular necrosis (5.5%) underwent CSRA. Patients including 68 females (63%) and 41 males (37%) underwent this procedure (63 right-sided and 46 left-sided including 9 bilateral shoulders). The outcome assessment included pain and satisfaction, Oxford Shoulder Score (OSS), Constant Score (CS), and SF-12. Imaging was reviewed for glenoid morphology (Walch classification) (Figure2) and humeral head migration. The average follow-up period was 4 years, (range: 1 to 10 years). Results. Primary OA and RA were the most common underlying pathologies in 45.9% and 39.4% of patients, respectively, followed by RCA (9.2%) and AVN (5.5%). Approximately 89% of arthroplasties were primary and 11% were revisions. Other body joints were affected in 85% of patients and nearly 70% of them had accompanying health conditions and co-morbidities (e.g. heart diseases, hypertension, and diabetes mellitus). A strong correlation found for OSS regarding CS and physical SF-12 subscale. Pain and physical limitation had negative correlation with satisfaction and shoulder-specific tools. Walch type A (68%) and superior HH migration (16.8%) were the commonest radiographic presentations. There was high correlation between migration and physical limitation, pain, satisfaction, OSS, and CS. A significant difference noted for OSS, CS, physical limitation, pain and satisfaction between migration and non-migration groups. Discussion. The CSRA provides pain relief and a good functional outcome in many patients. The main disadvantage is the technical difficult of implanting a glenoid which many surgeons now perceive as being essential in order to gain early pain relief and a better functional outcome. Our results show a predictable relationship between outcome and pathology, with osteoarthritic patients having the most favourable outcome. Glenoid wear and cuff related problems are the major reasons for failure. Improvements in the design and surgical technique to reduce the likelihood of HH migration remain the major challenge. CSRA should be considered the implant of choice in younger patients with osteoarthritis and RA where there is concern over conserving bone stock for future revision. Considering the nature of underlying pathologies it is appropriate to use a combination of generic and shoulder-specific outcome tools

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

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

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
