Reconstruction of chronic acromioclavicular joint disruption with artificial ligament prosthesis / 中华创伤杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>Management of Rockwood type 3 acromioclavicular disruptions is a matter of debate. Should we adopt conservative or operative measures at first presentation? It is not clear but most of the evidences are in favour of conservative management. We present our experience in managing these patients surgically.</p><p><b>METHODS</b>We present a prospective series of eight cases of chronic Rockwood type 3 acromioclavicular joint disruptions treated surgically. Anatomical reconstruction of the coracoclavicular ligament was done by artificial braided polyester ligament prosthesis.</p><p><b>RESULTS</b>All the patients were able to perform daily activities from an average of the 14th postoperative day. All patients felt an improvement in pain, with decrease in average visual analogue scale from preoperative 6.5 points (range 3-9 points) to 2.0 points (range 0-5 points), Constant score from 59% to 91% and American Shoulder and Elbow Surgeons shoulder score from 65 to 93 points postoperatively. These results improved or at least remained stationary on midterm follow-up, and no deterioration was recorded at an average follow-up of 46 months.</p><p><b>CONCLUSION</b>This midterm outcome analysis of the artificial ligament prosthesis is the first such follow-up study with prosthesis. Our results are encouraging and justify the further use and evaluation of this relatively new and easily reproducible technique.</p>
