Results of the Treatment of Acromioclavicular Dislocation Using Leeds-Keio Synthetic Ligament

Nine patients with complete acromioclavicular dislocation were treated with Leeds-Keio synthetic ligament, supplemented with a temporary fixation of the acromioclavicular joint. Seven patients were re-examined over an average of two years after the operation. The functional results were excellent in four patients, good in two and fair in one. However, we observed roentgenographic changes of the clavicle and the coracoid process, including subluxation of the acromioclavicular joint, erosion and circular sclerosis of the clavicle, and bone atrophy of the coracoid process by the Leeds-Keio synthetic ligament. Indication for the reconstruction of the coracoclavicular ligament using the Leeds-Keio synthetic ligament should be considered prudently.
