Abstract:
Objective To explore the clinical efficacy of small-incision Dewar's operation for acute acromioclavicular dislocation.Methods Without exposing the a-c joint,the coracoid tip with tendon were transferred to the clavicle to reconstruct the coracoclavicular ligaments.And then the a-c joint was statically fixed and dynamically replaced.Results A 1-to 9-year follow-up(mean,4.9 years)was available in 52 patients.According to the Lazzcano Criteria,44 cases had excellent and 7 cases had good results,only one was failed because of bolt prematurity at 2 month after the operation.Roentgenogram,CT,and MRI showed that the surface of the acromioclavicular joint was smooth,no arthritic sign of cirrhosis,hyperplasia,or theca.The signal of the a-c joint was uniform.The Roentgenograms showed that,at the neutrality position,the distal end of the clavicle of the injured side was higher than that of the healthy side.The D/W of the healthy side was 0.432?0.101,which was significantly higher than that in the injured side(0.523?0.083,t=2.188,P=0.042).The difference between the neutrality and hold of the healthy side was 0.116?0.025,while that of the injured side was 0.087?0.016(t=1.114,P=0.280).The Roentgenograms of the raise position showed no impact in the a-c joint.Conclusions Small incision Dewar's operation is an effective,safe,and minimally invasive method for the treatment of acute acromioclavicular dislocation.
