title: [Distraction osteogenesis for adjusting humeral length difference due to premature closure of the proximal growth plate in a simple bone cyst].
abstract: Complications after pathological fractures of simple bone cysts of the humerus are refracture, cyst recurrence, and in rare cases premature closure of the physeal plate with resulting shortening of the arm. Length discrepancies of the lower limbs beyond physiological limits need early compensation in children as well as adults to avoid interference with the pelvis and spine. However, surgical treatment of length differences of the humerus is usually cosmetic, because even considerable discrepancies do not lead to functional deficits. We report the long-term course of a complicated bone cyst of the proximal humerus and resolving a severe length difference of 7 cm by distraction osteogenesis in a young adult. The cause of the premature physeal closure and the primary therapeutical concept are discussed.
