ABSTRACT
In conclusion, internal impingement apparently occurs in nearly all patients and is demonstrable on MR imaging. Pathologic changes associated with internal impingement seem to develop with repetitive placement of the arm into a position of extreme external rotation and abduction. Findings may include lesions of the posterior superior labrum, undersurface irritation, or tearing of the supraspinatus-infraspinatus junction near the attachment site and cystic changes of the posterior superior glenoid and posterior lateral greater tuberosity. There is no evidence for a particular sequence of pathologic changes. Instability may be associated with but does not appear to be a prerequisite for the development of the pathologic lesions of internal impingement.
