Abstract

The shoulder as the most mobile joint in the body has a complex anatomy providing it with an increased range of motion, at the expense of its stability. The complex of ligaments and tendons around the acromioclavicular joint (ACJ) is prone to injury especially during sporting activity or following falls onto the apex of the shoulder. The original classification of ACJ dislocations having been modified by Rockwood suggests that types III to VI injuries may benefit from surgical intervention. Many procedures have been described to correct the deformity in the ACJ and to reestablish its ligamentous support. We describe a modification to the Weaver-Dunn procedure, which aims to establish a stable reduction with bone-to-bone healing, provided by bone plug fixation with Ethibond suture.
