Internal fixation of proximal humeral fractures.

Fractures of the proximal humerus are common, especially in elderly individuals, and are usually classified according to Neer into fractures having one, two, three, or four parts with or without an associated dislocation or an injury splitting the humeral head. This article is intended to assist the surgeon in selecting and using techniques for internal fixation of these fractures. The use of open reduction and internal fixation using plates and screws has become less popular because of the extensive dissection required and the tendency for the plate to impinge. Use of multiple percutaneous pins to fix the humeral head to the shaft (surgical neck) and heavy sutures or wires to reattach the tuberosities is often preferable.
