CPT® Code 24365

Arthroplasty of the radial head, as described by CPT® Code 24365, refers to a surgical procedure aimed at repairing or reconstructing the radial head, which is the top part of the radius bone in the forearm that forms part of the elbow joint. This procedure is typically indicated for patients suffering from conditions that lead to deterioration of the radial head, such as fractures, arthritis, or other degenerative joint diseases. The surgery can be performed using either a lateral or posterolateral approach, which involves making an incision in the forearm to access the radial head. During the procedure, the surgeon carefully exposes the annular ligament and identifies critical neurovascular structures to ensure they are protected throughout the operation. The damaged joint surface of the radial head is then removed, and various techniques may be employed to restore the joint's integrity and function. These techniques include covering the radial head with fascia to replace lost cartilage and bone, performing an interposition arthroplasty with materials such as fascia, cartilage, metal, or plastic, or conducting a gap arthroplasty that utilizes a decompression device to maintain the space between the remaining bony surfaces. This comprehensive approach aims to alleviate pain, restore mobility, and improve the overall function of the elbow joint.
