Degeneration of the acromioclavicular joint. A morphological study

One hundred and sixty-eight acromioclavicular joint dissections were performed on 85 cadavera, 46 men and 39 women, with an average age of 69, ranging from 18 to 92. The intra-articular discs and the joint cartilages were scrutinized and degenerative changes were graded macroscopically. An age related disintegration of the disc and the joint cartilages was found. After the age of 70 maximum degeneration was very common.
