Osseous adaptation and range of motion at the glenohumeral joint in professional baseball pitchers The throwing shoulder in pitchers frequently exhibits a paradox of glenohumeral joint motion in which excessive external rotation is present at the expense of decreased internal rotation. The purpose of this study was to determine the role of humeral head retroversion in relation to increased glenohumeral external rotation. >> more Rotator cuff repair: a biomechanical comparison of three techniques The most common complication of rotator cuff repair is structural failure at the repair site. A single-layer repair does not adequately reproduce the anatomic insertion and may not optimize fixation strength. >> more Biomechanics applied to sports medicine – an application to the superior labral anterior and posterior lesions in the overhead athlete The development of motion analysis and the application of biomechanical analysis techniques to sports have paralleled the exponential growth of computational and videographic technology. Technological developments have provided for advances in the investigation of the human body and the action of the human body during sports thought to be unobtainable a few years ago. >>more Differences in the ultimate strength of the biceps anchor and the generation of Type II superior labral anterior posterior lesions in a cadaveric model The pathogenesis of superior labral anterior posterior lesions remains controversial. The study hypothesized that the biceps anchor was more vulnerable to loading with a posterior vector as opposed to an in-line pull. >>more Electromyographic analysis of the rotator cuff and deltoid musculature during common shoulder external rotation exercise A prospective single-group repeated-measures study was performed to quantify electromyographic (EMG) muscle activity of the infraspinatus, teres minor, supraspinatus, posterior deltoid, and middle deltoid during exercises commonly used to strengthen the shoulder external rotators. >>more Copyright © 2000,
