Coracoid process transfer for acromioclavicular dislocation

Abstract

Seventeen patients with complete separation of the acromioclavicular joint were operated on acutely with transposition of the coracoid tip to the clavicle. All the patients were examined after a mean follow-up time of 7.5 years. Twelve patients had good function, 3 had slight pain in extreme positions, and 2 had poor function with pain at rest. Eleven patients had the screw removed, 2 of them because of deep infection. In 3 patients the coracoid tip fragmented during the operation. Two patients had an unsatisfying cosmetic result. As long as nonoperative treatment gives equal or better long-term functional results, we do not recommend this operation in acute dislocations.
