Stabilization of Acromioclavicular Joint Dislocation using the ‘Surgilig’ Technique

Abstract

BackgroundDisruption of the coracoclavicular ligaments may be associated with dislocation of the acromioclavicular joint, resulting in pain and functional disability. The Surgilig (Surgicraft Ltd, Redditch, UK) is a synthetic ligament used to reconstruct the ligaments, thereby stabilizing the joint.MethodsBetween 2004 and 2009, 50 patients with acromioclavicular joint dislocation were reconstructed using the Surgilig system. Five patients were lost to follow-up; hence, 45 patients underwent review. Patients were evaluated clinically and radiologically at an average of 26.9 months (range 6 months to 60 months) postoperatively using the Oxford, University of California, Los Angeles (UCLA) and Simple Shoulder scoring systems.ResultsThe mean Oxford score was 45.31 (SD 4.52, range 35 to 48), the mean UCLA score was 31.38 (SD 5.07, range 11 to 35) and the mean Simple Shoulder score was 10.92 (SD 1.7, range 6 to 12). Ninety-one percent of patients were completely satisfied with the procedure and outcome. Few complications were encountered, with no recorded infections. However, one patient underwent early revision for persistent instability. Six patients had the screw removed at a later stage as a result of local skin irritation. Removal of the screw did not result in recurrent instability.DiscussionThe present study is the largest reported mid-term results using the Surgilig technique, and appears to be successful for treating both acute and chronic injuries, with high patient satisfaction and excellent functional results.
