Anatomy of the coraco-acromial arch. Relation to degeneration of the acromion

J Bone Joint Surg Br. 1992 Jul;74(4):589-94. doi: 10.1302/0301-620X.74B4.1624522.


We examined 200 scapular bones for signs of degenerative changes in the coraco-acromial arch. The slope and length of the acromion and the height of the arch were found to be most closely associated with degenerative change. These anatomical features are not significantly altered by current techniques of subacromial decompression.
