Aims. The purpose of the present study was to evaluate the impact of intravenous tranexamic acid on the reduction of blood loss, transfusion rate, and early post-operative clinical outcome in total shoulder arthroplasty. Patients and Methods. A randomised, placebo-controlled trial which included 54 patients undergoing unilateral primary stemless anatomical or stemmed reverse total shoulder arthroplasty was undertaken. Patients received either 100 ml saline (placebo, n = 27), or 100 ml saline together with 1000 mg of tranexamic acid (TXA, n = 27) intravenously prior to skin incision and during wound closure. Peri-operative blood loss via an intra-articular drain was recorded and total blood loss was calculated. The post-operative transfusion rate was documented. Assessment of early clinical parameters included the visual analogue scale for pain (VAS), documentation of haematoma formation and adverse events. Results. Mean peri-operative blood drainage (placebo: 170 ml versus TXA: 50 ml, p = 0.001) and calculated mean total blood loss (placebo: 1248.2 ml versus TXA: 871.0 ml, p = 0.009) were significantly lower in the TXA group. No transfusions were necessary during the study period in either group. Mean VAS for pain significantly decreased from pre-operative (VAS 7) to the early post-operative period (VAS 1.7, p < 0.001). Significant differences regarding mean post-operative pain between placebo (VAS 2.0) and TXA (VAS 1.3) were detected (p = 0.05). The occurrence of haematomas was significantly more frequent in the placebo (59.3%, n = 16) than in the TXA group (25.9%, n = 6, p = 0.027). Whereas only mild haematomas developed in the TXA group, in the placebo group a total of 22.2% (n = 6) developed either moderate or severe haematomas. No adverse events associated with administration of TXA occurred. Conclusion. Intravenous administration of TXA successfully reduced mean peri-operative blood drainage, total estimated blood loss, pain during the first post-operative days, and haematoma formation in total shoulder arthroplasty.

Aims. To determine the incidence and timing of post-operative fevers following shoulder arthroplasty and the resulting investigations performed. Patients and Methods. A retrospective review was conducted of all patients undergoing shoulder arthroplasty over a nine-year period. The charts of all patients with a post-operative fever (≥ 38.6°C) were reviewed and the results of all investigations were analysed. Results. A total of 2167 cases (in 1911 patients) were included of whom 92 (4.2%) had a documented fever. Obese cases had a significantly greater risk for fever (relative risk 1.53; 95% confidence interval 1.02 to 2.32; p = 0.041). Investigations were performed in 43/92 cases (46.7%), with a diagnosis being made in six cases (6.6% of the total, two of whom had their diagnosis made post-discharge). Conclusion. Around one in 25 cases develop a fever following shoulder arthroplasty; most have no infective aetiology. These patients may be being over-investigated; investigations should be performed in patients with persistent fever or on those with an identifiable source of infection on clinical examination.

To prevent insufficiency of the triceps after total elbow arthroplasty, we have, since 2008, used a triceps-sparing ulnar approach. This study evaluates the clinical results and post-operative alignment of the prosthesis using this approach. We reviewed 25 elbows in 23 patients. There were five men and 18 women with a mean age of 69 years (54 to 83). There were 18 elbows with rheumatoid arthritis, six with a fracture or pseudoarthrosis and one elbow with osteoarthritis. Post-operative complications included one intra-operative fracture, one elbow with heterotopic ossification, one transient ulnar nerve palsy, and one elbow with skin necrosis, but no elbow was affected by insufficiency of the triceps. Patients were followed for a mean of 42 months (24 to 77). The mean post-operative Japanese Orthopaedic Association Elbow Score was 90.8 (51 to 100) and the mean Mayo Elbow Performance score 93.8 (65 to 100). The mean post-operative flexion/extension of the elbow was 135°/-8°. The Manual Muscle Testing score of the triceps was 5 in 23 elbows and 2 in two elbows (one patient). The mean alignment of the implants examined by 3D-CT was 2.8° pronation (standard deviation (. sd). 5.5), 0.3° valgus (. sd. 2.7), and 0.7° extension (. sd. 3.2) for the humeral component, and 9.3° pronation (. sd. 9.7), 0.3° valgus (. sd. 4.0), and 8.6° extension (. sd. 3.1) for the ulnar component. There was no radiolucent line or loosening of the implants on the final radiographs. . The triceps-sparing ulnar approach allows satisfactory alignment of the implants, is effective in preventing post-operative triceps insufficiency, and gives satisfactory short-term results. .

Aims. In the initial development of total shoulder arthroplasty (TSA), the humeral component was usually fixed with cement. Cementless components were subsequently introduced. The aim of this study was to compare the long-term outcome of cemented and cementless humeral components in arthroplasty of the shoulder. Patients and Methods. All patients who underwent primary arthroplasty of the shoulder at our institution between 1970 and 2012 were included in the study. There were 4636 patients with 1167 cemented humeral components and 3469 cementless components. Patients with the two types of fixation were matched for nine different covariates using a propensity score analysis. A total of 551 well-balanced pairs of patients with cemented and cementless components were available after matching for comparison of the outcomes. The clinical outcomes which were analysed included loosening of the humeral component determined at revision surgery, periprosthetic fractures, post-operative infection and operating time. Results. The overall five-, ten-, 15- and 20-year rates of survival were 98.9%, 97.2%, 95.5%, and 94.4%, respectively. Survival without loosening at 20 years was 98% for cemented components and 92.4% for cementless components. After propensity score matching including fixation as determined by the design of the component, humeral loosening was also found to be significantly higher in the cementless group. Survival without humeral loosening at 20 years was 98.7% for cemented components and 91.0% for cementless components. There was no significant difference in the risk of intra- or post-operative fracture. The rate of survival without deep infection and the mean operating time were significantly higher in the cemented group. Conclusion. Both types of fixation give rates of long-term survival of > 90%. Cemented components have better rates of survival without loosening but this should be weighed against increased operating time and the risk of bony destruction of the proximal humerus at the time of revision of a cemented humeral component.

Aims. To compare radiographic failure and re-operation rates of anatomical coracoclavicular (CC) ligament reconstructional techniques with non-anatomical techniques after chronic high grade acromioclavicular (AC) joint injuries. . Patients and Methods. We reviewed chronic AC joint reconstructions within a region-wide healthcare system to identify surgical technique, complications, radiographic failure and re-operations. Procedures fell into four categories: (1) modified Weaver-Dunn, (2) allograft fixed through coracoid and clavicular tunnels, (3) allograft loop coracoclavicular fixation, and (4) combined allograft loop and synthetic cortical button fixation. Among 167 patients (mean age 38.1 years, (standard deviation (. sd. ) 14.7) treated at least a four week interval after injury, 154 had post-operative radiographs available for analysis. . Results. Radiographic failure occurred in 33/154 cases (21.4%), with the lowest rate in Technique 4 (2/42 4.8%, p = 0.001). Half the failures occurred by six weeks, and the Kaplan-Meier survivorship at 24 months was 94.4% (95% confidence interval (CI) 79.6 to 98.6) for Technique 4 and 69.9% (95% CI 59.4 to 78.3) for the other techniques when combined. In multivariable survival analysis, Technique 4 had better survival than other techniques (Hazard Ratio 0.162, 95% CI 0.039 to 0.068, p = 0.013). Among 155 patients with a minimum of six months post-operative insurance coverage, re-operation occurred in 9.7% (15 patients). However, in multivariable logistic regression, Technique 4 did not reach a statistically significant lower risk for re-operation (odds ratio 0.254, 95% CI 0.05 to 1.3, p = 0.11). Conclusion. In this retrospective series, anatomical CC ligament reconstruction using combined synthetic cortical button and allograft loop fixation had the lowest rate of radiographic failure. . Take home message: Anatomical coracoclavicular ligament reconstruction using combined synthetic cortical button and allograft loop fixation had the lowest rate of radiographic failure.

Aims. The aim of the present study was to compare the 30- and 90-day re-admission rates and complication rates of outpatient and inpatient total shoulder arthroplasty (TSA). Patients and Methods. The United States Medicare Standard Analytical Files database was questioned to identify patients who had undergone outpatient or inpatient TSA between 2005 and 2012. Patient characteristics were compared between the two groups using chi-squared analysis. Multivariate logistic regression analysis was used to control for differences in baseline patient characteristics and to compare the two groups in terms of post-operative complications within 90 days and re-admission within 30 days and 90 days. Results. A total of 123 347 Medicare subscribers underwent TSA between 2005 and 2012; 3493 (2.8%) had the procedure performed as an outpatient. A significantly greater proportion of patients who underwent TSA as inpatients were women, had a history of smoking, and had a greater incidence of medical comorbidity including diabetes, coronary artery disease, congestive heart failure, and chronic kidney disease (p < 0.05 for all). Re-admission rates were significantly higher for inpatients at both 30 days (0.83% versus 0.60%, p = 0.016, odds ratio 1.8) and 90 days (2.87% versus 2.04%, p < 0.001, odds ratio 1.8). Complications, including thromboembolic events (p < 0.001) and surgical site infection (p = 0.002), were significantly higher in inpatients. Conclusion. Patients who underwent TSA on an outpatient basis were overall younger and healthier than those who had inpatient surgery, which suggests that patient selection was taking place. After controlling for age, gender, and medical conditions, patients who underwent TSA as outpatients had lower rates of 30- and 90-day re-admission and a lower rate of complications than inpatients. .

The indications for reverse shoulder arthroplasty (RSA) continue to be expanded. Associated impairment of the deltoid muscle has been considered a contraindication to its use, as function of the RSA depends on the deltoid and impairment of the deltoid may increase the risk of dislocation. The aim of this retrospective study was to determine the functional outcome and risk of dislocation following the use of an RSA in patients with impaired deltoid function. Between 1999 and 2010, 49 patients (49 shoulders) with impairment of the deltoid underwent RSA and were reviewed at a mean of 38 months (12 to 142) post-operatively. There were nine post-operative complications (18%), including two dislocations. The mean forward elevation improved from 50° (. sd. 38; 0° to 150°) pre-operatively to 121° (. sd . 40; 0° to 170°) at final follow-up (p < 0.001). The mean Constant score improved from 24 (. sd. 12; 2 to 51) to 58 (. sd. 17; 16 to 83) (p < 0.001). The mean Single Assessment Numeric Evaluation score was 71 (. sd. 17; 10 to 95) and the rate of patient satisfaction was 98% (48 of 49) at final follow-up. . These results suggest that pre-operative deltoid impairment, in certain circumstances, is not an absolute contraindication to RSA. This form of treatment can yield reliable improvement in function without excessive risk of post-operative dislocation. Cite this article: Bone Joint J 2013;95-B:1106–13

Aims. Radial head arthroplasty (RHA) may be used in the treatment of non-reconstructable radial head fractures. The aim of this study was to evaluate the mid-term clinical and radiographic results of RHA. Patients and Methods. Between 2002 and 2014, 77 RHAs were implanted in 54 men and 23 women with either acute injuries (54) or with traumatic sequelae (23) of a fracture of the radial head. Four designs of RHA were used, including the Guepar (Small Bone Innovations (SBi)/Stryker; 36), Evolutive (Aston Medical; 24), rHead RECON (SBi/Stryker; ten) or rHead STANDARD (SBi/Stryker; 7) prostheses. The mean follow-up was 74.0 months (standard deviation (. sd. ) 38.6; 24 to 141). The indication for further surgery, range of movement, mean Mayo Elbow Performance (MEP) score, quick Disabilities of the Arm, Shoulder and Hand (quickDASH) score, osteolysis and positioning of the implant were also assessed according to the design, and acute or delayed use. Results. The mean MEP and quickDASH scores were 90.2 (. sd. 14; 45 to 100), and 14.0 points (. sd. 12; 1.2 to 52.5), respectively. There were no significant differences between RHA performed in acute or delayed fashion. There were 30 re-operations (19 with, and 11 without removal of the implant) during the first three post-operative years. Painful loosening was the primary indication for removal in 14 patients. Short-stemmed prostheses (16 mm to 22 mm in length) were also associated with an increased risk of painful loosening (odds ratio 3.54 (1.02 to 12.2), p = 0.045). Radiocapitellar instability was the primary indication for re-operation with retention of the implant (5). The overall survival of the RHA, free from re-operation, was 60.8% (. sd. 5.7%) at ten years. Conclusion. Bipolar and press-fit RHA gives unsatisfactory mid-term outcomes in the treatment of acute fractures of the radial head or their sequelae. The outcome may vary according to the design of the implant. The rate of re-operation during the first three years is predictive of the long-term survival in tight-fitting RHAs. Cite this article: Bone Joint J 2017;99-B1197–1203

Aims. Manipulation under anaesthetic (MUA) is a recognised form of treatment for patients with a frozen shoulder. However, not all patients benefit. Some have persistent or recurrent symptoms. There are no clear recommendations in the literature on the optimal management of recurrent frozen shoulder after a MUA. We aimed to address this issue in this study. Patients and Methods. We analysed a prospectively collected, single-surgeon, consecutive series of patients who underwent MUA for frozen shoulder between January 1999 and December 2015. The Oxford Shoulder Scores (OSS) and range of movement were the outcome measures. . Results. A total of 730 patients (792 shoulders) underwent MUA during the study period. A further MUA was undertaken in 141 shoulders (17.8%), for which we had complete data for 126. The mean improvement in OSS for all patients undergoing MUA was 16 (26 to 42), and the mean post-operative OSS in those requiring a further MUA was 14 (28 to 42; t-test, no difference between mean improvements, p = 0.57). Improvement was seen after a further MUA, regardless both of the outcome of the initial MUA, and of the time of recurrence. Patients with type-1 diabetes mellitus were at a 38% increased risk of requiring a further MUA, compared with the 18% increased risk of the group as a whole (p < 0.0001). Conclusion. Patients with a poor outcome or recurrent symptoms of a frozen shoulder after a MUA should be offered a further MUA with the expectation of a good outcome and a low complication rate.

Aims. Depression can significantly affect quality of life and is associated with higher rates of medical comorbidities and increased mortality following surgery. Although depression has been linked to poorer outcomes following orthopaedic trauma, total joint arthroplasty and spinal surgery, we wished to examine the impact of depression in elective total shoulder arthroplasty (TSA) as this has not been previously explored. . Patients and Methods. The United States Nationwide Inpatient Sample (NIS) was used to identify patients undergoing elective TSA over a ten-year period. Between 2002 and 2012, 224 060 patients underwent elective TSA. Results. Among the identified patients who had undergone TSA, 12.4% had a diagnosis of a history of depression. A diagnosis of depression was twice as common in women compared with men (16.0% vs 8.0%, p < 0.001), and more frequent in those with low income and Medicaid insurance (p < 0.001). A diagnosis of depression was an independent risk factor for post-operative delirium (odds ratio (OR) 2.29, p < 0.001), anaemia (OR 1.65, p < 0.001), infection (2.09, p = 0.045) and hospital discharge to a placement other than home (OR 1.52, p < 0.001) . Conclusion. A history of clinical depression is present in 12.4% of patients undergoing elective TSA and the disease burden is projected to increase further in the future. Depression is often underdiagnosed and pre-operative screening and appropriate peri-operative management of patients is encouraged. Take home message: The awareness that clinical depression is associated with increased complications following total shoulder arthroplasty provides physicians an opportunity for early intervention in this at-risk population.

Aims. Revision total elbow arthroplasty (TEA) is often challenging. The aim of this study was to report on the clinical and radiological results of revision arthroplasty of the elbow with the Latitude TEA. Patients and Methods. Between 2006 and 2010 we used the Latitude TEA for revision in 18 consecutive elbows (17 patients); mean age 53 years (28 to 80); 14 women. A Kudo TEA was revised in 15 elbows and a Souter-Strathclyde TEA in three. Stability, range of movement (ROM), visual analogue score (VAS) for pain and functional scores, Elbow Functional Assessment Scale (EFAS), the Functional Rating Index of Broberg and Morrey (FRIBM) and the Modified Andrews’ Elbow Scoring System (MAESS) were assessed pre-operatively and at each post-operative follow-up visit (six, 12 months and biennially thereafter). Radiographs were analysed for loosening, fractures and dislocation. The mean follow-up was 59 months (26 to 89). Results. The ROM of the elbow did not improve significantly. The mean EFAS and MAESS scores improved significantly six months post-operatively (18.6 points, standard deviation (. sd. ) 7.7; p = 0.03 and 28.8 points, . sd . 8.6; p = 0.006, respectively) and continued to improve slightly or reached a plateau. The mean pain scores at rest (Z = -3.2, p = 0.001) and during activity (Z = -3.2, p = 0.001), and stability (Z = -3.0, p = 0.003) improved significantly six months post-operatively. Thereafter scores continued to improve slightly or a plateau was reached. There were no signs of loosening. Conclusion. Revision surgery using the Latitude TEA results in improvement of functionality, reduced pain and better stability of the elbow. Improvement of ROM of the elbow should not be expected.

Aims. Patient-specific glenoid guides (PSGs) claim an improvement in accuracy and reproducibility of the positioning of components in total shoulder arthroplasty (TSA). The results have not yet been confirmed in a prospective clinical trial. Our aim was to assess whether the use of PSGs in patients with osteoarthritis of the shoulder would allow accurate and reliable implantation of the glenoid component. Patients and Methods. A total of 17 patients (three men and 14 women) with a mean age of 71 years (53 to 81) awaiting TSA were enrolled in the study. Pre- and post-operative version and inclination of the glenoid were measured on CT scans, using 3D planning automatic software. During surgery, a congruent 3D-printed PSG was applied onto the glenoid surface, thus determining the entry point and orientation of the central guide wire used for reaming the glenoid and the introduction of the component. Manual segmentation was performed on post-operative CT scans to compare the planned and the actual position of the entry point (mm) and orientation of the component (°). Results. The mean error in the accuracy of the entry point was -0.1 mm (standard deviation (. sd. ) 1.4) in the horizontal plane, and 0.8 mm (. sd. 1.3) in the vertical plane. The mean error in the orientation of the glenoid component was 3.4° (. sd. 5.1°) for version and 1.8° (. sd. 5.3°) for inclination. Conclusion. Pre-operative planning with automatic software and the use of PSGs provides accurate and reproducible positioning and orientation of the glenoid component in anatomical TSA.

Aims. To date, there is insufficient evidence available to compare the outcome of cemented and uncemented fixation of the humeral stem in reverse shoulder arthroplasty (RSA). . Methods. A systemic review comprising 41 clinical studies was performed to compare the functional outcome and rate of complications of cemented and uncemented stems in RSA. These included 1455 cemented and 329 uncemented shoulders. The clinical characteristics of the two groups were similar. Variables were compared using pooled frequency-weighted means and relative risk ratios (RR). Results. Uncemented stems had a significantly higher incidence of early humeral stem migration (p < 0.001, RR 18.1, 95% confidence interval (CI) 5.0 to 65.2) and non-progressive radiolucent lines (p < 0.001, RR 2.4, 95% CI 1.7 to 3.4), but a significantly lower incidence of post-operative fractures of the acromion compared with cemented stems (p = 0.004, RR 14.3, 95% CI 0.9 to 232.8). There was no difference in the risk of stem loosening or revision between the groups. The cemented stems had a greater relative risk of infection (RR 3.3, 95% CI 0.8 to 13.7), nerve injury (RR 5.7, 95% CI 0.7 to 41.5) and thromboembolism (RR 3.9, 95% CI 0.2 to 66.6). The functional outcome and range of movement were equivalent in the two groups. . Discussion. RSA performed with an uncemented stem gives them equivalent functional outcome and a better complication profile than with a cemented stem. The natural history and clinical relevance of early stem migration and radiolucent lines found with uncemented stems requires further long-term study. Take home message: This study demonstrates that uncemented stems have at least equivalent clinical and radiographic outcomes compared with cemented stems when used for reverse total shoulder arthroplasty. .

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

We retrospectively assessed the value of identifying impinging osteophytes using dynamic computer simulation of CT scans of the elbow in assisting their arthroscopic removal in patients with osteoarthritis of the elbow. A total of 20 patients were treated (19 men and one woman, mean age 38 years (19 to 55)) and followed for a mean of 25 months (24 to 29). We located the impinging osteophytes dynamically using computerised three-dimensional models of the elbow based on CT data in three positions of flexion of the elbow. These were then removed arthroscopically and a capsular release was performed. The mean loss of extension improved from 23° (10° to 45°) pre-operatively to 9° (0° to 25°) post-operatively, and the mean flexion improved from 121° (80° to 140°) pre-operatively to 130° (110° to 145°) post-operatively. The mean Mayo Elbow Performance Score improved from 62 (30 to 85) to 95 (70 to 100) post-operatively. All patients had pain in the elbow pre-operatively which disappeared or decreased post-operatively. According to their Mayo scores, 14 patients had an excellent clinical outcome and six a good outcome; 15 were very satisfied and five were satisfied with their post-operative outcome. We recommend this technique in the surgical management of patients with osteoarthritis of the elbow. Cite this article: Bone Joint J 2014;96-B:237–41

Aims

Few studies have evaluated the relationship between patients’ pre-operative expectations and the outcome of orthopaedic procedures. Our aim was to determine the effect of expectations on the outcome after primary anatomical total shoulder arthroplasty (TSA). We hypothesised that patients with greater expectations would have better outcomes.

Aims

We assessed the long-term (more than ten-year) outcomes of the Kudo type-5 elbow prosthesis in patients with rheumatoid arthritis (RA).

Aim

The aim of this study was to report the long-term outcome and implant survival of the lateral resurfacing elbow (LRE) arthroplasty in the treatment of elbow arthritis.

Aims

Radiostereometric analysis (RSA) allows an extremely accurate measurement of early micromotion of components following arthroplasty.

Aims

Advances in arthroscopic techniques for rotator cuff repair have made the mini-open approach less popular. However, the mini-open approach remains an important technique for repair for many surgeons. The aims of this study were to compare the integrity of the repair, the function of the shoulder and satisfaction post-operatively using these two techniques in patients aged > 50 years.
