Abstract:
Objective Double-endobutton technique , as a widely accepted strategy for the treatment of acromioclavicular joint dislocation ( ACD ) , is undergoing constant improvement .This study was to assess the clinical effect of a modified closed-loop double-endobutton technique ( CDT) in the fixation of Rockwood type Ⅲ ACD . Methods This retrospective study included 60 cases of Rockwood type Ⅲ ACD treated between January 2010 and December 2015, 30 by modified CDT (MCDT) and the other 30 by conventional CDT (CCDT).We recorded and compared the operation time, incision length , intraoperative blood loss , pre-and post-opera-tive scores in the Constant-Murley Scale ( CMS ) , UCLA Shoulder Rating Scale ( SRS) , American Shoulder and Elbow Surgeons Rating Scale ( ARS) and Oxford Shoulder Score ( OSS), and the vertical distance from the supraclavian to subcoracoid plane ( CC-Dist ) be-tween the two groups of patients . Results Compared with the CCDT group, the MCDT group showed a significantly shorter operation time ([78.33±11.47] vs [52.33±8.48] min, P<0.05) and less intraoperative blood loss ([103.00±7.38] vs [79.17±9.75] mL, P<0.05).In comparison with the baseline, the patients of MCDT group achieved markedly improved scores at 12 months after surgery in CMS (46.60±2.09 vs 97.67±0.88, P<0.05), SRS (14.70±1.24 vs 32.17±1.21, P<0.05), ARS (44.23±2.40 vs 91.83±1.62, P<0.05), OSS (45.07±3.10 vs 15.80±1.81, P<0.05), and CC-Dist ([16.76±0.88] vs [7.57±0.73] mm, P<0.05). Conclusion MCDT, with the advantages of easier , tighter, and fas-ter reduction and fixation , is obviously superior to CCDT in the treatment of Rockwood type Ⅲ ACD .
