Corrective osteotomy after malunion of mid shaft fractures of the clavicle.

Displaced mid shaft fractures of the clavicle result in some degree of shortening and rotation. These fractures often heal with some degree of malunion which can be symptomatic. The question arises as to whether surgical correction of the deformity will relieve the symptoms associated with the malunion. Ten patients with a symptomatic malunion of the clavicle were treated by means of a corrective osteotomy with plate and screw fixation. Outcome measurement was a pre and postoperative DASH score, range of motion and patient satisfaction. At follow up after a mean duration of 37 months there was a significant improvement of the DASH score, eight patients were satisfied, and range of motion did not differ significantly. Two patients had a complication resulting from the surgical procedure.
