Replacement of radial head

Radial head prosthesis (RHP) is the primary solution for the treatment of unfixable radial head fractures, especially if also associated with complex elbow instability. The aim of the implant is to replicate the physiological tracking, reproducing the mechanical function of a native radial head. In this review we analyzed indications and types of implants. The surgical technique is also accurately discussed, considering this implantation with the same attention and precision used for the replacement of all the other joints. The most common complications after RHP are loosening, overstuffing, stiffness and heterotopic ossifications. However recent studies reported good clinical results in particular where correct rehabilitation programs were followed. Studies with high level of clinical evidence are necessary to provide definitive evidence to support the widespread use of this implant.
