Radial head fractures may occur in isolation in the elderly, in which case even moderately displaced radial head fractures can be treated nonoperatively, as long as there is not a block to motion. However, in younger patients, radial head fractures are often one component of a more complex injury, such as an elbow subluxation/dislocation or forearm axis injury. Our job is to identify those associated injuries and to determine whether repair or replacement of the radial head is necessary to restore stability. Olecranon fractures resulting from an indirect mechanism can be thought of his extensor mechanism injuries, and fixation simply needs to counteract those tensile forces. Direct or combined mechanisms may result in significant articular impaction and anterior elbow subluxation. In those instances, restoration of the articular surface and plate fixation are necessary. Subchondral locking screws can be used as rafts. The posterior variant is the most common type of Monteggia fracture dislocation in the adult. This is virtually always accompanied by a radial head fracture and may include a large coronoid component. The lateral collateral ligament may be involved. The constellation of injuries can usually be addressed through a single approach. Rigid fixation is critical.
