Two 14-year-old girls with voluntary dislocations of the shoulder were operated on. They had been suffering from symptoms of instability and we were impressed by their shyness. Their instabilities were multi-directional. Their shoulders' arthroscopes exhibited only a loose capsule and glenohumeral ligament without any bony displasia or osteochondral injuries. They could stop moving and dislocate shoulders voluntarily, after we explained them and their mothers that this motion deteriorates their symptoms. Case 1 inderwent a capsular shift and case 2 an arthroscopic capsulorraphy. The average morbid period was 16 months and their average follow-up period was 10 months. Their average JOA score was 73 points before surgery and 98 points after. There were no further redislocations or complaints of dullness. This ssems a less invasive method to treat patients to control voluntary dislocations.
