Radial Head Replacement
A Surgical Procedure to Replace a Damaged Radial Head and Restore Elbow Function
Radial head replacement involves replacing the damaged radial head (a part of the radius bone at the elbow) with an artificial implant. This procedure is typically performed when the fracture is too complex to heal naturally or with standard repair techniques.
Common Reasons for the Procedure:
- Complex fractures of the radial head that cannot be repaired.
- Associated ligament damage or elbow instability.
- Chronic pain and limited range of motion following trauma.
Goals of the Procedure:
- Relieve pain caused by the injury.
- Restore proper elbow alignment and stability.
- Improve range of motion and overall function.
Preparation for Surgery
Proper preparation can help ensure a smooth procedure and recovery.
Steps in Preparation:
- Pre-Surgical Consultation:
- Dr Ben McGrath will conduct a physical examination and review imaging tests such as X-rays, CT scans, or MRIs to assess the severity of the fracture and determine the need for replacement.
- Pre-Surgical Instructions:
- Follow specific instructions regarding fasting and stopping certain medications prior to surgery.
- Discuss your medical history, including allergies, current medications, and any previous surgeries.
- Lifestyle Adjustments:
- Stop smoking, as it may impair healing.
- Maintain a healthy weight to reduce strain on the elbow during recovery.
What Happens During the Surgery?
Radial head replacement is typically performed as an open surgical procedure under general or regional anaesthesia.
Procedure Steps:
- Anaesthesia:
- General anaesthesia or a regional block will be administered to minimise discomfort during the procedure.
- Surgical Technique:
- An incision is made over the elbow to access the joint.
- The damaged radial head is carefully removed.
- A prosthetic radial head, made of biocompatible materials, is inserted and secured.
- Stabilisation:
- The elbow ligaments and surrounding tissues are checked and repaired if necessary to ensure joint stability.
- Closing the Incision:
- The incision is closed with sutures or staples, and a dressing is applied.
Understanding the Risks
While radial head replacement is generally safe, there are potential risks associated with any surgical procedure.
Common Risks:
- Temporary pain, swelling, or stiffness in the elbow.
- Minor bleeding or bruising.
Rare but Serious Risks:
- Infection at the surgical site.
- Implant loosening or wear over time.
- Nerve or blood vessel injury.
Steps are taken to minimise these risks, including using sterile techniques and providing post-operative care instructions.
What to Expect After Surgery
Immediate Post-Operative Care:
- The arm will be immobilised with a splint or brace to support the elbow and aid healing.
- Pain management will include medications prescribed by Dr Ben McGrath.
Discharge Instructions:
- Avoid lifting heavy objects or performing strenuous activities with the affected arm.
- Follow wound care instructions to prevent infection.
- Attend follow-up appointments to monitor healing progress.
Rehabilitation and Recovery
Recovery involves a gradual return to normal activities with the support of physiotherapy.
Recovery Milestones:
- Weeks 1–3:
- Initial immobilisation with gradual introduction of gentle range-of-motion exercises as directed.
- Weeks 4–8:
- Begin strengthening exercises under the guidance of a physiotherapist.
- Months 2–3:
- Resume most daily activities, avoiding heavy lifting or high-impact activities until cleared by Dr Ben McGrath.
Restrictions During Recovery:
- Avoid weight-bearing activities on the affected arm until instructed.
- Follow all physiotherapy exercises for optimal recovery.
Long-Term Outcomes
Radial head replacement aims to restore elbow function and alleviate pain.
Expected Improvements:
- Pain relief and reduced swelling.
- Restored stability and range of motion in the elbow.
- Improved ability to perform daily activities.
Maintenance of Results:
- Protect the elbow from future injuries.
- Stay active and adhere to recommended follow-up care and physiotherapy.
