Diagnosis of Subacromial Abrasion.

Criteria for diagnosis

A. History

1. Limited function with arm in intermediate positions of elevation

B. Physical examination

1. Subacromial crepitance which reproduces the function-limiting symptoms, particularly on rotation of the humerus with the arm in intermediate positions of elevations

C. Radiographs

1. Diagnosis is supported by primary or secondary changes on the undersurface of the coracoacromial arch, such as acromial sclerosis or a traction spur in coracoacromial ligament
2. Diagnosis is supported by the coexistence of incomplete thickness cuff lesion or full thickness rotator cuff tear.
