Samenvatting
This chapter describes the bony structures of the proximal humerus.
The proximal humerus is often regarded as consisting of four
parts, which assists in understanding function and, more specially,
describes the essential parts in reconstruction after fracture or in
joint replacement. These are the humeral head, the lesser and greater
tuberosity and the humeral shaft. As the gleno-humeral joint has
a large arc of motion but minimal osseous stability, the capsular,
ligamentous restraints and dynamic muscular stabilisers are critical
to maintain stability. The humeral head is well vascularised, but
prone to avascular necrosis following a fracture.
