Variations in the anatomy of the scapula with reference to the snapping scapula

Abstract

Two clinical cases led to an examination of 700 scapular dry bone specimens in an effort to understand variations in anatomy of possible relevance to the development of a painful snapping scapula. The medial superior border and the inferior pole of the scapula respectively displayed areas of bony variability that appeared to be of clinical consequence in these 2 cases. The 2 areas are common sites of clinical symptomatology in the painful snapping scapula. Variations in the bony anatomy require consideration during the workup and evaluation of this condition.
