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.
