Radial Head Replacement is a surgical procedure in which a damaged or fractured radial head (the top part of the radius bone near the elbow) is replaced with an artificial implant. This procedure is usually recommended when the radial head is severely fractured, irreparable, or associated with elbow instability.

The radial head is the uppermost part of the radius bone in the forearm that forms part of the elbow joint. It allows for smooth rotation of the forearm and helps stabilize the elbow. Damage to this area can lead to pain, limited motion, and instability.

1Comminuted fractures (multiple fragments of the radial head that cannot be repaired)

2Failed previous surgeries or non-healing fractures

3Elbow instability due to ligament injuries

4.Arthritis or post-traumatic degeneration of the radial head

Severe pain on the outer side of the elbow

Swelling and bruising around the elbow joint

Limited range of motion, especially rotation of the forearm

Weakness in gripping or lifting objects

Clicking or popping sounds during movement

1.Anesthesia – The patient is given general or regional anesthesia.

2.Surgical Approach – The surgeon exposes the damaged radial head through a small incision.

3.Removal of Damaged Bone – The fractured or arthritic radial head is removed.

4.Implant Insertion – A prosthetic radial head is inserted to restore normal joint alignment and function.

5.Closure and Immobilization – The incision is closed, and the elbow may be placed in a splint for initial protection.

Hospital stay is usually 1–2 days, depending on the complexity of the surgery.

Early physiotherapy is crucial to restore movement and strength.

Full recovery typically takes 6–12 weeks, but gentle exercises often begin within days after surgery.

Regular follow-ups ensure proper implant function and healing.
