Discussion (see also: subacromial bursectomy) subacromial bursa is large synovial membrane which is adherent to undersurface of coracoacromial ligament, acromion, & delltoid laterally, an is adherent to rotator cuff & greater tuberosity; it envelops proximal humerus, & facilitates gliding of proxiaml humerus under coracoacromial arch References Synovial osteochondromatosis in the subacromial bursa. Subacromial/subdeltoid bursa abscesses. An overlooked diagnosis.
– Theory: – flexor-pronator muscles arising from medial epicondyle are transposed to more proximal point on the humerus so that their moment for elbow flexion is incresed enough to permit active control; – muscles originating from the medial epicondyle (Pronator Teres, FCR, PL, & FCU) must have normal or … Read more
