CPT® Code 24366

The procedure described by CPT® Code 24366 refers to an arthroplasty of the radial head, which involves the surgical replacement of the radial head with a prosthetic implant. This procedure is typically indicated for patients with significant damage or degeneration of the radial head, often due to conditions such as fractures, arthritis, or other joint disorders. The surgical approach can be lateral or posterolateral, depending on the specific case and the surgeon's preference. During the operation, an incision is made between the carpi radialis brevis and the extensor digitorum muscles to access the joint. The annular ligament, which stabilizes the radial head, is carefully exposed and freed from surrounding tissues to ensure that neurovascular structures are protected throughout the procedure. The radial head and neck are then fully exposed to allow for the removal of the damaged joint surface and the preparation of the site for the prosthetic implant. The use of a prosthetic implant aims to restore the function and integrity of the elbow joint, allowing for improved range of motion and stability post-surgery. Various techniques may be employed during the procedure to ensure optimal placement and function of the implant, ultimately enhancing the patient's recovery and quality of life.
