Operative Fixation of Radial Head Fractures

The radial head is an important structure that is crucial to the stability of both the elbow and forearm. Fractures of the radial head occur commonly and often are displaced or cause impingement to forearm rotation. Recent studies have further demonstrated the importance of maintaining or reconstructing the rigid buttress of the radial head. Advances in implant technology have benefited orthopedic surgeons in their attempts at fixation of the radial head and also in rigid implant arthroplasty. Partial articular fractures of the radial head are relatively simple to repair and can be stabilized with headless or buried screws. A complete articular fracture is more challenging and requires the use of rigid, lowprofile, and, often, fixed-angle plates placed in the nonarticular portion of the radial head. Associated ligament tears in the elbow magnify the importance of restoring the stabilizing effect of the radial head. Radial head excision should rarely be done and only after a thorough examination of the ligamentous structures about the elbow and forearm demonstrate complete stability.
