Injury to the suprascapular nerve associated with anterior dislocation of the shoulder: case report and review of the literature.

A young man with persistent pain beginning 2 days following reduction of an anterior subcoracoid dislocation was found to have a suprascapular nerve injury. The patient described was felt to have a neurapraxia of the suprascapular nerve. Possible causes of post-reduction subluxation are interposition of the shoulder joint capsule or biceps tendon, or rupture of the rotator cuff. EMG in 3 weeks, followup examinations, and active assisted motion 4 to 6 weeks postinjury are recommended.
