Surgical treatment of acute and chronic acromioclavicular dislocation Tossy type III and V using the Hook plate.

We treated 16 patients with acute and chronic acromioclavicular dislocations type III and V by open reduction and fixation using a Hook plate (AO). Plate removal was performed 7 months later on average (range 3 1/2 - 13). A clinical and radiological follow-up was performed after a mean time interval of 29 months (range, 11-40) from the date of plate removal. The L'Insalata scoring system was used to compare the function of the injured shoulder before operation and after removal of the hook plate. Constant's score was used to evaluate the operated shoulder after the removal of the hook plate. Complications were limited and the overall results were excellent.
