The Clinical Efficacy Comparision Of Two Kinds Of Operations For Type â…¢ Acromioclavicular Dislocation

Objective: To compare the therapeutic effects of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation in treating Tossy type Ⅲ acromioclavicular(AC) joint dislocation.Methods:To analyze the data of patiens, who suffering Tossy type Ⅲacromioclavicular joint dislocation and received operation in our hospital’s Department of Orthopedics from January 2012 to January2014.Forty-one patients with fresh Tossy type Ⅲ acromioclavicular joint dislocation were reviewed.All patients were divided into clavicular hook-plate fixation group(group A)and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation group(group B) according to surgical procedures. There were 21 patients in group A,and the preoperative Constant-Murley score was 40.25±9.80. At the same time,there were 20 patients in group B, and the preoperative Constant-Murley score was 41.45±8.81.Operative time,blood loss, imaging changes before and after operation, postoperative complications were compared; Constant-Murley score at 3,6 and 12 months after operation were evaluated. Results: In group A, operative time was(40.50±24.36)min,blood loss was(75.30±30.36)ml.In group B, operative time was(60.10±23.55)min, blood loss was(100.70±40.12)ml. Twenty-one patients in group A were followed-up from 12 to 18 months with an average of(14.8±3.1)months; twenty patients in group B were followed-up from 12 to 14 months with an average of(13.6±1.5)months.There were no significant differences in operative time, blood loss and follow-up time between two groups. Six patients were occurred complications in group A and 3 patients in group B,and there were no significant meaning between two groups.At 6 months after operation,Constant-Murley score in group A was(88.15±1.59),(92.15±1.95) in group B; and had significant meaning between two groups( t=-7.21,P=<0.001).While there were no differences in Constant-Murley score in other times.Conclusion:.Clavicular hook-platefixation has advantage of less trauma,while modified Weaver-Dunn surgery combined with clavicular hook-plate fixation could reconstruct coracoclavicular ligament more stronger,clavicular hook plate could take out earlier,also improve should joint function earlier.
