Osteophytes as a stigma for shoulder impingement syndrome and osteoarthritis of the acromioclavicular (AC) joint were studied on the acromions and AC joints in 346 skeletons (230 males; 116 females), ranging in age from 15–100 years. Osteophytes were found on 28.9% (200/692) of the acromions, mostly on the anteroinferior aspect (54%; 108/200). Of these 28.9%, 87% (174/200) were of the traction type and 13% (26/200) of the claw type. Regarding the clavicles, 11.6% (80/692) had osteophytes on the articular facets of their lateral ends; all were of the traction type. There were statistically more osteophytes on the right than on the left side of both acromion and clavicle ( P < 0.05). The occurrence of osteophytes and increasing age were significantly correlated ( r = 0.65, P < 0.001). No gender differences were noted in the frequency of osteophytes on acromions or clavicles. These data should prove beneficial to clinicians in planning a proper course of treatment for patients suffering from painful conditions of the shoulder. Clin.
