Partial Hip Replacement

Partial hip replacement involves replacing the femoral head—the ball part of the hip joint—with a prosthetic implant, while leaving the natural socket intact. This approach is different from total hip replacement, where both the ball and socket are replaced. By targeting only the damaged portion, hemiarthroplasty minimizes surgical complexity and helps patients regain mobility more quickly.

This procedure is most often recommended for:

• Patients with fractures of the femoral neck or head.
• Elderly individuals with osteoporosis-related hip fractures.

Patients who may not tolerate longer anaesthesia , more complex surgeries due to medical conditions.

Partial hip replacement is generally performed under general or regional anesthesia. The procedure involves:

1. Incision and Access – An incision is made on the side of the hip to expose the joint.
2. Removal of the Damaged Femoral Head – The fractured or damaged femoral head is carefully removed.
3. Placement of Prosthetic Implant – A metal or ceramic prosthetic ball, attached to a stem, is inserted into the thigh bone. The implant is secured either with bone cement or using a press-fit technique, depending on the patient’s bone quality and surgical plan.
4. Joint Stabilization – The prosthetic ball is placed into the natural socket, allowing smooth movement.
5. Closure and Dressing – The incision is closed, and the hip is supported during the initial healing period.

Recovery after partial hip replacement is typically shorter compared to total hip replacement. Most patients are encouraged to begin moving the joint within a few days of surgery to prevent stiffness and complications. Rehabilitation usually includes:

• Early Mobilization – Assisted walking with support aids like crutches or walkers.
• Physical Therapy – Guided exercises to restore strength, balance, and range of motion.
• Strength Building – Gradual return to weight-bearing activities as healing progresses.
• Lifestyle Adjustments – Careful monitoring to avoid falls or reinjury during recovery.

Depending on age, health, and extent of the injury, patients may return to most normal activities within a few weeks to a few months.

• Less invasive compared to total hip replacement.
• Shorter surgical time and reduced anesthesia exposure.
• Faster recovery and rehabilitation.
• Effective pain relief and improved joint function.
• Preserves the natural socket, reducing complexity.

Partial Hip Replacement (Hemiarthroplasty) is a proven surgical option for individuals with severe hip fractures affecting the femoral head or neck. By replacing only the damaged ball of the joint and preserving the socket, it offers pain relief, quicker recovery, and restoration of mobility. While not suitable for every patient—especially those with advanced arthritis—it remains one of the most effective treatments for fracture-related hip conditions. With proper rehabilitation and care, patients can regain independence and return to a more active lifestyle.
