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 \u003c 0.05). The occurrence of osteophytes and increasing age were significantly correlated (r = 0.65, P \u003c 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."}
