The stiffness of the coracoclavicular ligaments and their surgical replacments have previously been reported; however, the mechanism of failure and procedures for repair include both the clavicle and coracoid process which have not been investigated. Therfore, this study utilized a physiolgogic mechanism of injury to compare the stiffness of the coracoclavicluar ligament and anatomic reconstruction complexes, both overall and individual complex components. After dislocation of the coracoclavicular ligament complex, a 40% decrease of the clavicle stiffness was observed along with a more comparable stiffness of the reconstruction tendon graft to the intact coracoclavicular ligaments compared to current repair materials. These findings suggest all components of the coracoclavicluar complex following dislocation should be considered in selection of rehablilation protocols or surgical procedures.

The acromioclavicular joint is stabilized by two ligaments: the acromioclavicular ligaments and coracoclavicular ligaments. AC joint dislocations account for 9% to 10% of all shoulder injuries. Tossy and Allman classified acromioclavicular dislocations into three types (I, II and III). This classification was modified by Rockwood (types IV, V, and VI). Type I and II dislocations are treated conservatively. Surgery is indicated for certain Rockwood type III and for all type IV, V, and VI injuries. A 45 years old man yoga trainer presented to our emergency department with a chief complaint of pain over his left shoulder after had traffic accident 3 hours prior to admission. Physical examination revealed left lateral clavicular end prominent and tenderness over the left shoulder with limited range of motion due to pain. A Zanca view X-Ray of left shoulder was performed and revealed dislocation of acromioclavicular joint. The patient was diagnosed with suspect Left AC joint disruption grade III. We performed coracoclavicular ligament reconstruction using a gracilis tendon graft 2 days after the accident. Before the surgery, constant score of the patient left shoulder was 25 (Fair). The constant score measured was 63 after 10 month follow up. Coracoclavicular ligament reconstruction with an autogenous gracilis tendon graft was feasible and safe in physically active patients with acute type-III acromioclavicular joint dislocation.
