title: [Capsular shift for voluntary dislocation of the shoulder: results in children].
abstract: OBJECTIVE
  Chronic shoulder instability is uncommon in patients with an immature skeleton. Some of these pediatric patients can produce their dislocation voluntarily raising the question of the traumatic or constitutional nature of the condition as well as its direction and tolerance. We report our experience with 29 patients.
  
  
  METHODS
  Over a period of 28 years, 29 children aged 5 to 15 years were treated for voluntary shoulder dislocation. The dislocation was painful and poorly tolerated in 19, affecting daily life and sports activities. Posterior dislocation was observed in 15 patients and anterior dislocation in 4, but the direction was not always easy to establish, particularly in children with ligament laxity; multiple directions were not uncommon. Rehabilitation for at least eight months did not relieve pain in 11 patients who had a sensation of a blocked, unreliable shoulder which could not be controlled voluntarily. Posterior capsulorrhaphy was performed in 8 patients and anterior capsulorrhaphy in 3.
  
  
  RESULTS
  Mean follow-up was 8 years. At last follow-up, all shoulders were stable and shoulder motion was normal with no loss of function. More than half of the children had resumed sports activities. Capsulorrhaphy was proposed when the pre-operative explorations did not reveal any bone or rim anomaly. The only preoperative finding in the operated patients was increased capsule volume, particularly in the inferior portion. Intraoperatively, ulceration of the humeral cartilage was found in two patients. Anatomic reconstruction of the capsuloligamentary structures enabled recovery of passive stability and active stability of the scapulohumeral joint, preventing further voluntary dislocation.
