Recurrent posterior instability of the shoulder: surgical treatment.

: A total of 11 cases of posterior instability of the shoulder surgically treated by simple capsuloplasty or associated with reinforcement of the posterior wall by bone graft or muscle transposition were reviewed. Accurate selection and preoperative evaluation of the patient when choosing surgery is very important. For surgery to succeed prolonged postoperative immobilization and an intense rehabilitative program to be initiated prior to surgery are necessary. Generalized ligamentous hyperlaxity constitutes a negative factor in prognosis, so that it is important to associate capsuloplasty with posterior bone block, in an attempt to avoid the risk of recurrence as further surgery would have an unfavorable outcome.
