ELBOW

Radial head prosthesis

A radial head prosthesis is used:

– when a fracture of the radial head (at the elbow) is too complex to be reliably repaired. The fractured bone is then replaced by a metal implant that replicates the shape and function of the joint,

– when the after-effects of old fractures become disabling.

The aim is to restore stability to the elbow, preserve flexion-extension and rotational (proton supination) movements of the forearm, and enable a rapid return to function.

This procedure is often carried out in conjunction with ligament repair when the ligaments are also damaged (following a dislocation) or in the case of a complex fracture of the ulna.

Early rehabilitation is generally initiated to minimise stiffness in the elbow and facilitate a return to everyday activities.
