my glenohumeral and a.c. joint are congruent. slight cortical irregularity at the inferior glenoid is identified. they are asking if I have history of injury to suggest fracture by exray..my question is how far back is the history as I have never fractured my shoulder but have demonstrate a partial thickness supraspinatus tear with query an anterior labral tear in left shoulder due to overuse. what happens if I continue to do repetitive work with it.
