Retrospective review of outcome post open reduction and K-wire fixation for grade III acromioclavicular joint subluxations.

There is controversy about the therapy for grade III acromioclavicular dislocation according to Tossy and Rockwood's classification. We identified 25 patients who underwent acromioclavicular joint wiring for grade III subluxations under the care of a single consultant in the last 5-year period. All patients were asked to fill in a DASH (Disabilities of the Arm, Shoulder and Hand) questionnaire to assess outcome following acromioclavicular joint repair, and their clinical notes were reviewed. Our results show that open reduction and Kirschner- (K) wire fixation of grade III AC joint disruptions results in good strength and range of motion of the affected shoulder. It is associated with DASH scores, which are comparable to those of the general population for the same age, indicating little residual disability. All patients returned to their pre-injury occupation, and all but one returned to previous sporting activities. Complications occurred in four patients, but only one required K-wire repositioning.
