Abstract

In 1941, Bosworth used noncannulated coracoclavicular lag screw to Oeat acute A-C joint dislocation. In 1989, Tsou fixed coracoclavicular joint with percutaneous cannulated screw under general anesthesia in the treatment of acute A-C joint complete dislocations. We tried to treat 10 cases of acute A-C joint dislocations with cannulated screw fixation of C-C joint under local anesthesia, so we report the results with review of literatures. The results were as follows 1. Results of treatment were good in 7 cases, fair in 2 cases, and poor in 1 case by Weaver and Dunn evaluation criteria. 2. The operations were done under local anesthesia, but in two cases operation ended under general anesthesia due to discomfort of the patients. 3. In skeletally thin patient, it was very difficult to make accurate hole and we experienced an iatrogenic fracture of clavicle and coracoid process. This technique is not recommendable in skeletally thin patient. 4. Operation took 42 minutes on average(from 30 minutes to 105 minutes) though it took more time in the early cases. 5. We had several complications in 3 patients. Misdirection of screw(1 case), screw loosening and pull out(1 case), subluxation of A-C joint after removal of screw(2 cases), and iatrogenic fracture of clavicle and coracoid process(1 case) but no case of metal breakage or infection.
