Treatment of complete acromioclavicular separations with a modified Weaver and Dunn technique

The purpose of this article is to describe the indications, operative technique, and postoperative rehabilitation protocol for treatment of complete acromioclavicular separations. A modified Weaver and Dunn technique is described, with a detailed harvesting procedure of the coracoacromial ligament, along with a wafer of bone for anatomical reconstruction of the coracoclavicular ligaments. A suture anchor is used to provide temporary stability to the acromioclavicular joint while the transferred coracoacromial ligament heals in the new position.
