Abstract
The modified Bosworth’s method has been performed since 1994 for fresh cases of acromioclavicular dislocation belonging to grade III of the Tossy classification. 16 cases treated at our hospital were retrospectively studied by direct examination and questionnaire survey. 11 patients were men and 5 were women, whose mean age was 42 years. The mean period from injury to surgery was 14 days. The mean follow-up period was 4 years and 2 months.
Evaluation was made according to the Japan Shoulder Society (JSS) score for acromioclavicular joint. Radiological evaluation was made of subluxation, osteoarthrotic changes, and coracoclavicular ossification. In addition, the correlation of results to radiological findings and that of results with period of internal fixation was studied.
We observed subluxation in 1 shoulders, osteoarthrotic changes in 4 shoulders. And we simultaneously obserbed coracoclavicular ossification, subluxation and osteoarthrotic changes in 1 shoulder. Of the full score of 90 points of the JSS score, the score ranged from 50 to 90 points with a mean of 80.0 points. These results were satisfactory, being comparable to those of other treatment. No adverse effect of postoperative subluxation, osteoarthrotic changes of acromioclavicular joint, coracoclavicular ossification, and longer period of internal fixation was observed on our clinical results.
