Abstract
During a 5.5-year period, we treated 64 patients with acute acromioclavicular separations by surgical recon struction. According to the classification of Rockwood and Matsen, 54 patients had type III lesions, 1 patient had a type IV lesion, and 9 patients had type V lesions. Both the coracoclavicular ligaments and the ligaments of the acromioclavicular joint were reconstructed. An additional ligamentous augmentation was performed using completely resorbable 5- and 10-mm polydiox anonsulphate bands. Forty-five patients (70%) were re- examined at 2 to 7.5 years after surgery (mean, 32 months). The results were good or excellent in 40 cases (89%). Forty-one patients (92%) achieved a range of motion with an abduction deficit of less than 20°. Cal cifications in the area of the coracoclavicular or acro mioclavicular ligaments did not affect the final range of motion. Complications consisted of one subcutaneous infection, one deep infection, and one failure of the re construction. Augmenting the reconstruction with poly dioxanonsulphate bands allowed an early functional postoperative treatment. With this procedure, patients do not require removal of an implant, and complications from breakage or migration of metal implants are avoided.
