Abstract

Pathology of the acromioclavicular (AC) joint spans the spectrum from acute traumatic separation to chronic degenerative change. Degenerative changes are frequently seen on plain radiographs, but are not universally symptomatic. On T2 sequences of MRI, bony edema correlates more frequently with symptomatic as opposed to asymptomatic individuals. Operative treatment includes arthroscopic distal clavicle excision. Traumatic separations of the AC joint are classified based on ligamentous injuries and the resulting relationship between the positions of the distal clavicle and the acromion. There are many different options for operative management of AC separations. Suprascapular nerve compression at the suprascapular notch can present with vague shoulder pain and be diagnosed with MRI showing mass lesion, atrophy of supraspinatus and infraspinatus, and EMG.
