MR imaging of osteochondral and articular lesions.

abstract：:Internal causes of impingement are secondary to rotator cuff and capsular dysfunction and are categorized by the location of the impingement and the underlying pathophysiological or mechanical cause of the impingement. These include posterosuperior impingement, anterosuperior impingement, anterior impingement, and ent...
