Hip Joint Fusion, medically known as Arthrodesis, is a surgical procedure designed to relieve chronic hip pain by permanently fusing the bones of the hip joint. Unlike hip replacement, which restores mobility, this surgery eliminates movement in the joint to provide stability and pain relief. It’s typically recommended when other treatments fail, especially for younger patients with severe arthritis or traumatic injuries.
During the procedure, the damaged cartilage is removed, and the femur (thigh bone) is fixed to the pelvis using screws, plates, or bone grafts. Over time, the bones grow together, creating a single, solid structure. While this means the hip won’t bend, it can significantly improve quality of life for those struggling with debilitating pain.
Though less common today due to advancements in hip replacement surgeries, arthrodesis remains a viable option for specific cases where mobility isn’t the primary concern. Understanding the benefits, risks, and recovery process can help patients make informed decisions about their treatment.
Hip arthrodesis is usually considered a last-resort treatment when other interventions, such as medications, physical therapy, or less invasive surgeries, fail to provide relief. Common reasons for this surgery include:
This surgery is often recommended for younger, active patients (under 40) who need a durable, long-term solution. Since fusion eliminates hip motion, candidates must have healthy knees and spine to compensate for the lack of movement. A thorough evaluation by an orthopedic surgeon is essential to determine suitability.
Proper preparation is crucial for a successful outcome. Here’s what patients can expect:
Medical Evaluation: Your surgeon will conduct imaging tests (X-rays, MRI, or CT scans) and assess overall health to rule out complications like infections or blood clotting disorders.
Lifestyle Adjustments: Smoking cessation is critical, as nicotine slows bone healing. Patients may also need to stop certain medications (e.g., blood thinners) temporarily.
Prehabilitation: Physical therapy before surgery strengthens surrounding muscles, improving recovery. Learning to use crutches or a walker in advance is also helpful.
Home Modifications: Rearranging furniture, installing grab bars, and setting up a recovery space on the ground floor can ease post-surgery mobility challenges.
On the day of surgery, patients should fast (as directed) and arrive early for pre-operative procedures. Bringing loose clothing and a support person is advisable.
Hip arthrodesis is performed under general anesthesia and typically takes 3–4 hours. Here’s a breakdown:
Patients usually stay in the hospital for 3–5 days for monitoring. Pain management and early mobilization with assistive devices begin immediately.
Recovery from hip fusion is lengthy but manageable with proper care:
First 6 Weeks: Non-weight-bearing (using crutches or a walker) is mandatory to allow bone fusion. Physical therapy focuses on upper-body strength and gentle leg exercises.
Weeks 6–12: Partial weight-bearing begins if X-rays show healing. Therapists introduce gait training and flexibility exercises for the knees and spine.
3–6 Months: Most patients resume light activities. Full fusion takes 6–12 months, after which the joint is permanently stable.
Long-term, patients may need shoe lifts to balance leg length discrepancies and should avoid high-impact activities. Regular follow-ups ensure the fusion is successful.
While hip arthrodesis is generally safe, potential risks include:
Choosing an experienced surgeon minimizes these risks. Patients should report unusual pain, swelling, or fever promptly.
Weighing these factors with your surgeon is key to making the right choice.
For patients hesitant about fusion, alternatives include:
Your surgeon will recommend options based on age, activity level, and joint condition.
Q: Will I walk normally after hip fusion?
A: Yes, but with a slight limp. The fused hip shifts movement to the knees and spine.
Q: Can the fusion be reversed later?
A: No, it’s permanent. Conversion to a hip replacement is possible but complex.
Q: How long until I can drive?
A: Typically 8–12 weeks, depending on recovery progress.
