Spur reformation after arthroscopic acromioplasty

Rotator cuff pathology has been associated with a hooked acromial morphology. Impingement syndrome has traditionally been considered to be the result of bony encroachment into the subacromial space. This report of a spur recurrence after acromioplasty presents evidence that acromial morphology may be a reactive change attributable to primary rotator cuff insufficiency.
