[Four part valgus impacted fractures of the upper extremity of humerus: ilium graft reconstruction. Apropos of 8 cases].

Abstract

This specific type of displaced four-part fracture of the proximal humerus which consists of valgus impaction of the head fragment without lateral displacement has a rate of avascular necrosis lower than that of other displaced four-part fractures. Blood supply of the articular segment is maintained via the periosteum extending to the medial part of the anatomic humeral neck. These data authorized the authors to propose a new conservative treatment for four-part valgus impacted proximal humeral fractures.
