The purpose of this study is to report the results of surgical treatment for a fractured coracoid process in acromio-claviclar joint separation. We experienced 8 shoulders with a fractured coracoid process in A-C joint separation. They all consisted of men. Their ages ranged from 11 to 45 years old. The affected sides were 5 right shoulders and 3 left. According to Ogawa's classification, coracoid fractures were type III in 5 shoulders and type IV in 3. According to Tossy's classification, A-C joint injuries were grade I in 1 shoulders and grade II in 1 and grade III in 6. There were 7 fresh injuries and a old one. In the fresh cases, the coracoid process was fixed by a screw after the A-C joint had been repositioned by a k-wire. The old case was treated by Dewar's method. The ORIF of the coracoid process was not perfect in some cases, but a union was achieved in all cases. There were 2 subluxations of the A-C joint. The ROM had improved and painless during ADL. To treat a fractured coracoid process on A-C joints separration, good results were obtained using a fixation of the coracoid fragments after a temporaty fixation of the A-C joints. If a fractured coracoid process is suspected in a AC separation, cephalic tilt view should be taken.
