BACKGROUND This study compared the use of reverse and hemishoulder arthroplasty for the treatment of proximal humeral fractures among orthopedic surgeons taking part II of the American Board of Orthopaedic Surgery board examination. We hypothesized that the use of reverse shoulder arthroplasty for fractures in the elderly is increasing amongst newly trained(More)
BACKGROUND To address persisting controversy in the literature concerning the efficacy of arthroscopic compared to open acromioplasty, a meta-analysis was performed to evaluate the treatment effect after both approaches. HYPOTHESIS The final clinical outcomes will be the same after both open and arthroscopic acromioplasty. However, the arthroscopic(More)
PURPOSE The purpose of this study was to determine the effect of coracoclavicular (CC) fixation on biomechanical stability in type IIB distal clavicle fractures fixed with plate and screws. METHODS Twelve fresh-frozen matched cadaveric specimens were used to create type IIB distal clavicle fractures. Dual-energy x-ray absorptiometry (DEXA) scans ensured(More)
Little information exists on the molecular and biochemical pathophysiology of subacromial bursitis and rotator cuff disease. We investigated the pattern of expression of cytokines (interleukin [IL]-1beta, IL-1, IL-6, tumor necrosis factor [TNF] alpha, small inducible cytokines), metalloproteases, and cyclooxygenases in the subacromial bursa in patients with(More)
BACKGROUND Controversy remains regarding the results of all arthroscopic rotator cuff repairs compared with the mini-open approach. The purpose of this study was to perform a comprehensive literature search and meta-analysis of clinical trials comparing the results of arthroscopic rotator cuff repairs and mini-open rotator cuff repairs. HYPOTHESIS There(More)
PURPOSE The pathophysiology of subacromial impingement syndrome is poorly understood. We investigated the expression of inflammatory cytokines, metalloproteases, and the cyclooxygenases in the subacromial bursa in control patients and in patients with rotator cuff tear. TYPE OF STUDY Basic science evaluation. METHODS Eighteen patients undergoing(More)
This clinical practice guideline is based on a systematic review of published studies on the treatment of glenohumeral osteoarthritis in the adult patient population. Of the 16 recommendations addressed, nine are inconclusive. Two were reached by consensus-that physicians use perioperative mechanical and/or chemical venous thromboembolism prophylaxis for(More)
BACKGROUND Considerable debate exists over the use of radiofrequency-based chondroplasty to treat partial-thickness chondral defects of the knee. This study used second-look arthroscopy to evaluate cartilage defects previously treated with bipolar radiofrequency-based chondroplasty. HYPOTHESIS Partial-thickness articular cartilage lesions treated with(More)
