Abstract

• PURPOSE: The purpose of this study is to evaluate the clinical result of surgical reconstruction of the old traumatic radial head dislocation in children, and to delineate the optimal surgical procedure for it. MATERIALS AND METHODS: Fifteen cases of the old traumatic radial head dislocation were included in this study, which had surgical reconstruction at the age of 15 years or less. Preoperative and postoperative clinical symptom, range of joint motion, and radiologic findings were reviewed. Reconstructions were performed by combination of various procedures, and the advantages and disadvanges of each procedures were analyzed. RESULTS: All the preoperative complaints were relieved by the operation. In twelve cases out of 15, the radial head reduction was well maintained. The reasons for the loss of reduction were non-union of ulnar osteotomy site, and the neglected angular deformity at the proximal radius. Although forearm pronation was decreased in most cases, they did not affect most of the daily activities except in cases where the radioulnar osseocartilaginous bridge were complicated. CONCLUSION: Our results justify the surgical reconstruction of neglected traumatic radial head dislocations in children. Complete clearing of radiocapitellar joint, accurate bony realignment and rigid fixation, appropriate annular ligament reconstruction, and temporary fixation with transcapitellar pin may ensure satisfactory result.
