Narrow coraco-humeral distance measuring 8.5 mm (Normal > 10 mm) which predispose to subcoracoid impingement and subscapularis tear.
There is partial subscapularis tear , subcoracoid bursitis and moderate joint effusion extending along the long head of biceps tendon sheath.
Os acromiale (normal variant) is noted.
