title: Comminuted fracture-dislocations of the elbow treated with an AO wrist fusion plate.
abstract: Comminuted fracture-dislocations of the elbow are complex injuries that can result in significant postoperative loss of motion. Rigid anatomic fixation with early range of motion is the required treatment. Because of the local anatomy of the proximal ulna, it often is difficult to achieve a rigid fixation construct. A fixation technique of a dorsally applied AO limited contact-dynamic compression wrist fusion plate contoured to fit the anatomy of the proximal ulna is presented. Advantages of the AO wrist fusion plate in comminuted olecranon fractures include the ease of contouring, a low profile, and the use of variable screw hole sizing to achieve stable fixation. The hybrid design allows for rigid 3.5-mm plate fixation distally while providing low profile 2.7-mm plate fixation over the subcutaneous olecranon. The technical and biomechanical features of this plate make it an ideal alternative for fixation of these complex injuries.
