RESUMEN
PURPOSE: To find out the problem of modified Bosworth method and improve the method of operation. MATERIALS AND METHODS: 21patients treated with modified Bosworth method were evaluated after a minium follow-up period of two years. The results were analysed clinically and reontgenographically. RESULTS: In postoperative X-ray evaluation, the coracoclavicular interval of the operated side was decreased by an average of 0.8 mm compared with that of the normal side. There was no significant difference in coracoclavicular interval between after screw removal and last follow-up. Loosening of the screw was seen in 3 of the 5 cases overcorrected by more than 2 mm and the result was fair in two of them. A satisfactory result was obtained in 17 (81.1%) of the 21 cases. CONCLUSION: Modified Bosworth method for acute complete acromioclavicular dislocation yields better results provided the overcorrection and anterior displacement of the clavicle are appropriately protected.
