Abstract
Posttraumatic avascular necrosis of the humeral head (AVN) can lead to joint destruction with persistent pain and functional limitation. Fractures of the proximal humerus can proceed with disruption of the blood supply of the humeral head and then frequently lead to osteonecrosis and destruction of the humeral head’s surface. The risk of AVN after proximal humeral fractures has been described to depend on the type of the fracture. After 3-part fractures according to Neer [14] the incidence has been described to be 3–14 % and after 4- part fractures from 13 up to 34 % [5]. If the congruency of the joint is lost, destruction of the entire joint may follow and surgical treatment is frequently necessary [16].
