Radial Head Arthroplasty with a Modular Metal Spacer

David C. Ring, MD, PhD, Graham J.W. King, MD, MSc, FRCSC and Ruby Grewal, MD MSc, FRCSC

Comminuted fractures of the radial head are challenging to treat with open reduction and internal fixation. Radial head arthroplasty is an alternative treatment with results that compare favorably with those reported after open ORIF of similar fractures. In this JBJS/VJO video supplement, doctors Grewal and King from Ontario, Canada, discuss important intraoperative points while demonstrating their surgical technique for implanting a modular radial head prosthesis. Dr. David Ring, of Boston, Massachusetts, provides additional commentary on the surgical technique. A key feature of the design includes a stem that allows for rotational motion at both the implant/bone interface and radiocapitellar articulation, potentially reducing capitellar wear. There are 150 different combinations of heads and stems that permit minimal bone removal while optimizing fit.
