Abstract
Recurrent dislocation of the shoulder is a fairly common and disabling disorder. The anterior type predominates, and the basic lesions and operative treatment of the posterior type are counterparts of those of anterior lesions. Conservative measures sometimes may be advised, but after a second or third dislocation operative treatment is indicated. Repair of the anterior capsular mechanism by one of the standard technics gives freedom from recurrence in more than 95 per cent of cases. Range of motion and power of the affected joint can be restored to normal in the majority.
