Abstract
Introduction There is limited medium-term outcome data regarding the predictors of functional outcome and patient satisfaction after arthroscopic rotator cuff repair. Methods 287 patients that underwent arthroscopic rotator cuff repair under a high-volume single surgeon were contacted at a minimum of 4 years following surgery. Patient demographics, tear size and co-morbidities were pre-operatively recorded. The Oxford shoulder score, EuroQol 5-dimensional score and patient satisfaction were recorded at final follow-up. Results 234 (81.5%) patients completed follow-up at a mean of 5.5 (4-9) years. There were 126 males and 108 females with a mean age of 60 (range 25-83) years. The majority of patients (n = 211, 90%) were satisfied with their final outcome. Multivariate linear regression analysis (R 2 = 0.64) identified that increasing tear size (p = 0.04), worsening general health assessed by the EuroQol 5-Dimensional (p < 0.001), and smoking (p = 0.049) were associated with a worse Oxford shoulder score. Logistic regression analysis (R 2 = 0.13) identified that worsening general health assessed by the EuroQol 5-Dimensional (p < 0.001), and smoking (p = 0.01) were associated with an increased risk of patient dissatisfaction. Conclusion General health status and smoking are independent predictors of functional outcome and patient satisfaction at medium-term follow-up following arthroscopic rotator cuff repair.

Abstract
Background Stemless shoulder arthroplasty using 4 open-fin press-fit anchors has been showing promising short-term clinical and radiographic results for patients' primary osteoarthritis. This prospective, multicenter study presents 5-year postoperative clinical and radiological outcomes of a stemless shoulder arthroplasty for primary osteoarthritis. Methods Between November 2012 and December 2015, 100 patients were treated for primary osteoarthritis with the Sidus stem-free shoulder system at 7 European centers. Clinical assessment included the Constant-Murley Score, American Shoulder and Elbow Standardized Shoulder Assessment Form score, Subjective Shoulder Value, and range of motion. True anteroposterior, axial and lateral radiographs were reviewed for osteolysis, glenoid and humerus loosening, heterotopic ossification, radiolucent lines, component migration and humeral bone resorption. In addition to a Kaplan-Meier survival analysis, a comparative analysis between total shoulder arthroplasty and hemiarthroplasty was performed. Results Seventy-one patients (36 females) with a mean age of 63.8 years (range: 47-79 years) were available for the 5-year clinical and radiographic follow-up (range: 52-79 months). There was a significant increase (P < .0001) in all outcome scores compared to baseline values. Patients with total shoulder arthroplasty (n = 48) achieved significantly better functional outcome than patients with shoulder hemiarthroplasty (n = 23) with regard to the absolute and relative Constant-Murley Score, American Shoulder and Elbow Standardized Shoulder Assessment Form score, and Subjective Shoulder Value as well as greater abduction strength and range of motion in forward elevation and external rotation (P ≤ .004). There were no cases of osteolysis or humeral loosening. There were some cases of heterotopic ossification (1.4%), radiolucency around the humerus (1.4%) or glenoid (25%), glenoid migration (2.1%), inferior osteophytes (1.4%) or humerus bone resorption (9.9%). The 5-year survival was 94%. Conclusion Patients treated with the Sidus stem-free shoulder system for primary osteoarthritis continue to achieve good clinical and radiographic results without any signs of aseptic humeral implant loosening at 5 years postsurgery.

Abstract
BACKGROUND The primary aim of this study was to determine the cost-effectiveness of the reverse total shoulder arthroplasty in a prospective cohort of patients over a two-year post-operative period. METHODS Patients who underwent reverse total shoulder arthroplasty were prospectively monitored for 24 months post-operatively using the Oxford Shoulder Score, Disabilities of the Arm, Shoulder and Hand questionnaire and EuroQol 5-dimensional questionnaire. Any complications or use of health care resources were recorded. The incremental cost-effectiveness ratio was used to express the cost per quality-adjusted life year gained. RESULTS Sixty-seven patients were analysed, 46 primary reverse total shoulder arthroplasty for cuff arthropathy and 21 revisions from previous arthroplasty. Both indications had comparable peri-operative shoulder scores without significant difference. Using the mean change of EuroQol 5-dimensional questionnaire at one year, the incremental cost-effectiveness ratio was calculated at £16,827.43 per quality-adjusted life year, decreasing to £8313.48 per quality-adjusted life year at two years. Primary was associated with a lower incremental cost-effectiveness ratio at two years (primary £7596.76 vs. revision £11,748.51). The estimated post-operative life expectancy of the cohort was 6.9 years with a projected cost per quality-adjusted life year of £2438.78. CONCLUSIONS Reverse total shoulder arthroplasty provides a cost-effective intervention with excellent patient outcomes at two years post-operatively.

Abstract
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
BACKGROUND The aim of this prospective multicenter study was to evaluate clinical and radiologic results of a new metaphyseal anchored system. This system features a different anchor geometry that potentially leads to better bony integration and less loosening. METHODS From November 2012 until December 2015, 148 patients (151 shoulders) were treated with the Sidus Stem-Free Shoulder System at 9 centers in Europe. The main indication was primary osteoarthritis (80.1%). This analysis only includes patients diagnosed with primary osteoarthritis (n = 121). A clinical evaluation was performed using the Constant-Murley score, Subjective Shoulder Value, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, and range of motion. Radiologic assessment was based on the occurrence of radiolucent lines and signs of implant migration, osteolysis, loosening, and heterotopic ossification. RESULTS We evaluated 105 patients after a follow-up period of 2 years. There were 53 women and 52 men. The average age was 64 years. Total shoulder arthroplasty was performed in 73 cases and hemiarthroplasty in 32. The Constant-Murley score improved from 26 points preoperatively to 70 points at 2 years' follow-up (P < .001). The Subjective Shoulder Value increased from 34% to 84% (P < .001), and the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form increased from 34 points to 86 points (P < .001). Radiologically, neither migration nor loosening was found. However, radiolucent lines of 2 mm or greater could be detected around the glenoid in 2 cases, but none of them have had clinical relevance yet. The overall complication rate was 6.7%, and the revision rate was 0%. CONCLUSION Patients with the Sidus Stem-Free Shoulder System achieve good clinical and radiologic short-term results that are comparable with the results of other stem-free shoulder implants.

Abstract
We compared the outcome of arthroscopic repair of the rotator cuff in 32 diabetic patients with the outcome in 32 non-diabetic patients matched for age, gender, size of tear and comorbidities. The Constant-Murley score improved from a mean of 49.2 (24 to 80) pre-operatively to 60.8 (34 to 95) post-operatively (p = 0.0006) in the diabetic patients, and from 46.4 (23 to 90) pre-operatively to 65.2 (25 to 100) post-operatively (p = 0.0003) in the non-diabetic patients at six months. This was significantly greater (p = 0.0002) in non-diabetic patients (18.8) than in diabetics (11.6). There was no significant change in the mean mental component of the Short-Form 12, but the mean physical component increased from 35 to 41 in non-diabetics (p = 0.0001), and from 37 to 39 (p = 0.15) in diabetics. These trends were observed at one year. Patients with diabetes showed improvement of pain and function following arthroscopic rotator cuff repair in the short term, but less than their non-diabetic counterparts.

Abstract
BACKGROUND Capsular laxity is the main pathology in patients with multidirectional instability, and thermal shrinkage has been commonly employed to treat this condition. The objective of this study was to evaluate thermal capsular shrinkage as a treatment of multidirectional instability of the shoulder. METHODS Nineteen consecutive patients with multidirectional instability were treated with thermal shrinkage. Fifteen patients had involuntary instability, and four had voluntary instability. The predominant direction of the instability was anteroinferior in ten patients and posterior in five; four patients had instability in multiple directions. Patients were followed for a minimum of two years or until surgical failure and recurrence of symptoms. Postoperatively, the patients wore a sling for three weeks, and they were evaluated regularly at three, six, and twelve months. The Western Ontario Shoulder Instability Index as well as subjective and objective evaluations of the patient's function, range of motion, pain, and instability were used as clinical outcome measures. RESULTS Nine patients had recurrence of the instability at an average of nine months (range, seven to fourteen months) following the surgical procedure. Four patients had sensory dysesthesias in the axillary nerve distribution, and one of them had deltoid weakness. All neurological symptoms resolved within nine months. The surgical procedure failed in the five patients with predominantly posterior instability. It failed in only two of the ten patients with predominantly anteroinferior instability, and overall this group had objective improvement. CONCLUSIONS Thermal capsular shrinkage used to treat multidirectional instability had a substantial failure rate with associated postoperative complications, including recurrence of instability (nine of the nineteen patients), stiffness (five patients), and neurological symptoms (four patients).

Abstract
BACKGROUND Hip fracture patients have a high risk of thromboembolic complications following surgical management. OBJECTIVES To examine the effects of heparin (unfractionated (U), and low molecular weight (LMW) heparins), and physical methods (compression stockings, calf or foot pumps) for prevention of deep venous thrombosis (DVT) and pulmonary embolism after surgery for hip fracture in the elderly. SEARCH STRATEGY We searched the Cochrane Musculoskeletal Injuries Group trials register, Medline, Embase, and reference lists of published papers and books. We contacted trialists and other workers in the field. Date of most recent search: September 1996. SELECTION CRITERIA Randomised and quasi-randomised trials evaluating the use of heparins and physical agents for prevention of DVT and pulmonary embolism in patients undergoing surgery for hip fracture. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed methodological quality and extracted data. Trials were grouped into four categories (heparin versus control, mechanical versus control, LMW heparin versus U heparin, and miscellaneous) and results pooled where possible. MAIN RESULTS The 26 included trials involved 2600 predominantly female and elderly patients. Overall, trial quality was disappointing. Ten trials involving 826 patients which compared U heparin with control, and four trials of 471 patients which compared LMW heparin with control, showed a reduction in the incidence of lower limb DVT (121/511 (24%) versus 203/519 (39%); Peto odds ratio 0.41; 95% confidence interval 0.31 to 0.55). There were insufficient data to confirm the efficacy of either agent in the prevention of pulmonary embolism. There was a non significant increase in overall mortality in the heparin group (46/420 (11%) versus 35/423 (8%); Peto odds ratio 1.39; 95% confidence interval 0. 86 to 2.23). Data were inadequate for all other outcomes including wound complications. There is insufficient evidence from five trials, involving 644 patients, to establish if LMW heparin was superior to U heparin. Most trials evaluating heparins had methodological defects. Four trials, involving 442 patients, testing mechanical pumping devices were also methodologically flawed, and so pooled results need to be viewed cautiously. Mechanical pumping devices may protect against DVT (12/202 (6%) versus 42/212 (19%); Peto odds ratio 0.24; 95% confidence interval 0.13 to 0.44). Although the limited data indicated a potential benefit, they were inadequate to establish any effect on the incidence of pulmonary embolism and overall mortality. Problems with skin abrasion and compliance were reported. REVIEWER'S CONCLUSIONS U and LMW heparins protect against lower limb DVT. There is insufficient evidence to confirm either protection against pulmonary embolism or overall benefit, or to distinguish between various applications of heparin. Foot and calf pumping devices appear to prevent DVT, may protect against pulmonary embolism, and reduce mortality, but compliance remains a problem. Good quality trials of mechanical methods as well as direct comparisons with heparin should be considered.

Abstract
The epidemiology of ankle fractures is changing. Increasing longevity has resulted in the highest age-specific incidence of ankle fractures being in women between 75 and 84 years of age. The introduction of the AO classification has facilitated analysis of the commonest fracture types. This survey of 1,500 ankle fractures, seen in a 3-year period in the Edinburgh Orthopaedic Trauma Unit, shows that the commonest ankle fractures are the B1.1 and A1.2 lateral malleolar fractures. Isolated malleolar fractures accounted for two thirds of the series, with bimalleolar fractures occurring in one fourth of the patients and trimalleolar fractures in the remaining 7%. Open fractures occurred in 2%.

Abstract
We describe a new technique for open reduction, bone grafting and fixation with a single Kirschner wire of unstable fractures of the distal radius. Of the 83 patients treated by this technique, most had regained volar tilt when seen at an average of 13 months after injury. Malunion was seen in 18 patients due either to poor placement of the graft and Kirschner wire or because of both volar and dorsal comminution. Assessment of hand and wrist function showed an average recovery of 63% of mass grip strength with an excellent return of specialised grip strength and range of movement. The advantages of this technique over closed methods include the ability to regain the volar tilt of the distal radius and to achieve reduction at any time before union of the fracture.

Abstract
We performed transoesophageal echocardiography in 111 operations (110 patients) which included medullary reaming for fresh fractures of the femur and tibia, pathological lesions of the femur, and hemiarthroplasty of the hip. Embolic events of varying intensity were seen in 97 procedures and measured pulmonary responses correlated with the severity of embolic phenomena. Twenty-four out of the 25 severe embolic responses occurred while reaming pathological lesions or during cemented hemiarthroplasty of the hip and, overall, pathological lesions produced the most severe responses. Paradoxical embolisation occurred in four patients, all with pathological lesions of the femur (21%); two died. In 12 patients large coagulative masses became trapped in the heart. Extensive pulmonary thromboembolism with reamed bone and immature clot was found at post-mortem in two patients; there was severe systemic embolisation of fat and marrow in one who had a patent foramen ovale and widespread mild systemic fat embolisation in the other without associated foraminal defect. Sequential analysis of blood from the right atrium in five patients showed considerable activation of clotting cascades during reaming.

Abstract
We performed an epidemiological analysis of 523 fractures treated in the Edinburgh Orthopaedic Trauma Unit over a three-year period using modern descriptive criteria. The fractures were defined in terms of their AO morphology and their degree of comminution, location and cause. Closed fractures were classified using the Tscherne grading system and open fractures according to the Gustilo classification. Further analysis of fractures caused by road-traffic accidents and football was carried out. The use of the AO classification allowed the common fracture patterns to be defined. Correlation of the classification systems showed an association between the AO morphological system and the Tscherne and Gustilo classifications. The relative rarity of severe tibial fractures is indicated and it is suggested that in smaller orthopaedic units the infrequency of these fractures has implications for training and the development of treatment protocols.

Abstract
Acute phase proteins are released into the circulation as part of the metabolic response to trauma. C reactive protein (CRP) has been shown to be the most specific and sensitive indicator of trauma. We measured pre- and postoperative CRP levels in patients undergoing varicose vein surgery, inguinal herniorrhaphy, laparoscopic cholecystectomy and open cholecystectomy. A significant difference is shown between the levels found in those undergoing varicose vein, hernia surgery or open cholecystectomy; however, there is no significant difference in the CRP levels between open and laparoscopic cholecystectomy.
