Palmaris longus tendon graft versus modified Weaver-Dunn procedure via dynamic button system for acromioclavicular joint reconstruction in chronic cases

Background The hypothesis of this clinical study was that coracoclavicular (CC) reconstruction using autogenic palmaris longus graft through the GraftRope (PLG) system (Arthrex, Inc., Naples, FL, USA) would provide superior clinical and radiologic results compared with modified Weaver-Dunn procedure with the dynamic TightRope (Arthrex, Inc.) system (WDT). Methods Between 2008 and 2013, 32 patients (average age, 39.7 years; range, 22-60 years) underwent surgical reconstruction of chronic acromioclavicular (AC) joint dislocation. A modified WDT procedure was performed in 16 patients and autogenous PLG was performed in the other 16 patients. Patient data were collected retrospectively, with a final follow-up of 44.9 months (range, 29-60 months). The degree of AC joint displacement was evaluated by measuring the CC distance on the anteroposterior and axillary view. Clinical and functional outcomes were compared by American Shoulder and Elbow Surgeons and the Constant scores at final follow-up. Results Comparison between the WDT and PLG groups showed a significantly better outcome in the American Shoulder and Elbow Surgeons and the Constant scores ( P P Conclusion CC palmaris longus tendon graft reconstruction with GraftRope system was associated with functional and radiologic benefits. The palmaris longus graft with GraftRope system could be used in chronic cases.
