Abstract
BACKGROUND: The purpose of this study was to identify the clinical and radiological outcomes of hook plate fixation for lateral end fracture of the clavicle and acromioclavicular dislocation.
METHODS
There were a total of 20 cases with lateral end fracture of the clavicle and 16 cases with acromioclavicular dislocation. All patients were evaluated for range of motion, functional score by using Constant score, and American Shoulder and Elbow Surgeons shoulder index at just before implant removal and at final follow-up. Coracoclavicular distance was measured in acromioclavicular dislocation and bony union was evaluated in the lateral end fracture of the clavicle.
RESULTS
The clinical outcomes and range of motion were increased at the final follow-up compared with just before implant removal in both the lateral end fracture of the clavicle and acromioclavicular dislocation. In acromioclavicular dislocation, all cases?except one?showed maintenance of reduction after implant removal. Moreover, in the lateral end fracture of the clavicle, all cases?except one?showed bony union.
CONCLUSIONS
Hook plate fixation in the lateral end fracture of the clavicle and acromioclavicular dislocation resulted in good clinical and radiological results.
