Abstract
[Purpose]
We treated type 3 acromioclavicular dislocation (Tossy's classification) by a modified Dewar's method, and evaluated the results after follow-up for more than 4 years.
[Subjects and methods]
Between 1987 and 1992,15 patients with acromioclavicular dislocation were operated on at our department by a modified Dewar's method. Eleven patients (8 men and 3 women) who were followed-up for more than 4 years were studied. Their mean age was 32.2 years. Nine patients had a fresh dislocation and 2 had an old dislocation. Temporary fixation of the acromioclavicular joint with Kirschner wires for 6 weeks was added to the original Dewar's method. Stockinet Velpeau external fixation was applied for 3 weeks, after which Codman's exercises were started. We evaluated the shoulder joint function using the Japanese Orthopaedic Association's (JOA) score and Kawabe's criteria.
[Results]
The mean follow-up period was 64 months. The mean JOA score was 94.3 points and all 11 patients had an excellent outcome. The mean score for Kawabe's criteria was 91.1 points, with 8 patients rated as excellent and 3 as good.
[Conclusion]
We treated acromioclavicular dislocation by a modified Dewar's method and achieved good results.
