Coracoclavicular ligament reconstruction using a semitendinosus graft for failed acromioclavicular separation surgery.

Although acromioclavicular joint separations are fairly common, the occurrence of high-grade acromioclavicular separations that require surgery is low. Various modifications of the Weaver-Dunn procedure have been popular and fairly successful methods to treat severe acromioclavicular separations, despite the fact that reconstructions have been done a number of ways. We report on the results of a technique for salvaging failed modified Weaver-Dunn reconstructions using a semitendinosus graft through bone tunnels in the distal clavicle and coracoid to reconstruct the coracoclavicular ligament.
