Arthroplasty of the elbow with distal humeral prosthetic replacement is a surgical procedure aimed at addressing severe joint damage or dysfunction in the elbow. This procedure involves the replacement of the distal end of the humerus with a prosthetic implant, which is designed to restore function and alleviate pain. The surgery typically begins with a skin incision made over the elbow joint, either on the medial or lateral side of the olecranon process, allowing access to the joint. During the operation, careful dissection of the soft tissues is performed, with particular attention given to the ulnar nerve, which is identified and protected to prevent injury. The lateral epicondyle of the humerus is exposed, and the surgical team navigates through the surrounding structures, including the anconeus and flexor carpi ulnaris muscles, to access the elbow joint. The procedure involves meticulous steps to ensure proper alignment and fit of the prosthetic implant, including the reaming of the humeral canal and the placement of a trial implant to verify the dimensions before the final implant is secured with bone cement. Post-surgery, the elbow is stabilized, and the arm is placed in a splint to facilitate healing. This procedure is indicated for patients with significant elbow joint degeneration, often due to conditions such as arthritis or trauma, and aims to improve the patient's range of motion and quality of life.
