Minimum five-year outcomes of reverse total shoulder arthroplasty using a trabecular metal glenoid base plateAIMS: 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.

Acromioclavicular joint disruptions: A comparison of two surgical approaches 'hook' and 'rope'INTRODUCTIONAcromioclavicular joint injuries are common shoulder girdle injuries most commonly resulting from a direct blow to the acromion with the arm adducted. Type-I or type-II acromioclavicular joint injuries can be managed with sling immobilization, early shoulder motion, and physiotherapy. The management of type-III injuries remains controversial and is individualized. Type IV and V injuries should be treated surgically. A myriad of surgical techniques for the management of acromioclavicular joint injuries have been reported.METHODSWe present a comparative study of 76 patients treated with two most common modalities of treatment for AC joint disruption and that is Hook plate stabilisation (n=52) or arthroscopically assisted tight rope stabilisation (n=24). The primary objective was to establish whether hook plate stabilization was superior compared to arthroscopic tight rope fixation in reducing pain and increasing function in the short-term and long-term for patients with AC joint disruptions III-IV. We also wanted to assess how quickly patients returned to their work/job. It was a prospective study, we included all the patients operated between 2008 and 2015 for AC joint disruption by the two shoulder surgeons of our department. All patients followed a strict physiotherapy protocol and were assessed at 6 weeks, 3 months and 12 months. We used the Harm and cost criteria of assessment and the patient specific functional outcome scores.RESULTSBoth modalities of treatment have high patient satisfaction rate, return to work is faster in tight rope group but after a year both group of patients returned to their premorbid state. Removal of hook plate is not mandatory and lysis of acromion is rare (1% in our series).CONCLUSIONDespite the fact that both methods yielded similar results and have statistically similar number of complications, the type of postoperative complications was different between groups. The plate group had more postoperative pain and worse function but both aspects improved after plate removal. The rope group had more complex complications including deep infection and recurrence of deformity and fracture. These differences should be taken into consideration when consenting the patient regarding possible treatment.

Effectiveness of scapula-focused approaches in patients with rotator cuff related shoulder pain: A systematic review and meta-analysisBackground: Rotator cuff related shoulder pain (RCSP) is common with a range of conservative treatments currently offered. Evidence supporting superiority of one approach over another is lacking. Scapula focused approaches (SFA) are frequently prescribed and warrant investigation. Objective: To evaluate the effectiveness of SFA in RCSP. Design: Systematic review of randomised controlled trials. Methods: An electronic search including MEDLINE, PEDro, ENFISPO to January 2016 was supplemented by hand searching. Randomised controlled trials were included; appraised using the PEDro scale and synthesised via meta-analysis or narratively, where appropriate. Results: Four studies (n = 190) reported on pain and three studies (n = 122) reported on disability. Regarding pain, there was statistical but not clinically significant benefit of SFA versus generalised approaches (mean difference (VAS) 0.714; 95% CI 0.402-1.026) in the short term (< 6 weeks); regarding disability, there was significant benefit of SFA versus generalised approaches (mean difference 14.0; 95% CI 11.2-16.8) in the short term (< 6 weeks). One study (n = 22) reported disability at 3 months, which was not statistically significant. Evidence is conflicting from four studies relating to the effect of SFA on scapula position/movement. Conclusion: SFA for RCSP confers benefit over generalised approaches up to six weeks but this benefit is not apparent by 3 months. Early changes in pain are not clinically significant. With regards to scapula position/movement, the evidence is conflicting. These preliminary conclusions should be treated with significant caution due to limitations of the evidence base.
