Acromioclavicular joint reconstruction using anchor sutures: surgical technique and preliminary results.

A number of surgical procedures have been described for reconstruction of the disrupted acromioclavicular (AC) joint. Among these is the use of anchor sutures tied over a small button plate. The present study aims to evaluate the preliminary results with this technique in 15 patients with a mean age of 31 years (range: 19-48 years). The shoulder was evaluated clinically using the Constant-Murley Shoulder Score, and radiologically. Indication for surgery was Rockwood type IV-V AC joint dislocation. All patients returned to work within a mean time of 11.2 weeks (range 8-18) postoperatively. The mean Constant-Murley Shoulder Score at last follow-up was 92.8. Postoperative radiographs confirmed anatomic reduction in all patients. Residual subluxation occurred in one patient and dislocation occurred in another. All patients except one were satisfied with the results in terms of functional performance and cosmetic appearance. In conclusion, considering its low morbidity, unnecessary hardware removal and minimal complications from breakage or migration of metal implants, this technique appears to offer a good alternative in AC joint stabilization.
