Radial head implant arthroplasty.

Radial head arthroplasty has developed into a reliable procedure to address fractures of the radial head not amenable to reconstruction, particularly when associated with an unstable elbow or forearm. Good to excellent results can be anticipated when used for the correct indications and when care is taken to understand and address the concomitant injuries. This article will discuss the technique of radial head arthroplasty in the context of the injuries that often accompany radial head fractures.
