Name of the Procedure:

Hallux Implant (L8642)

• Common Names: Big Toe Joint Replacement, Great Toe Implant
• Technical/Medical Terms: Hallux Metatarsophalangeal Joint Arthroplasty

Summary

A Hallux implant procedure involves surgically replacing the damaged metatarsophalangeal (MTP) joint of the big toe with an artificial implant. This helps restore function and alleviate pain, allowing better movement and stability.

Purpose

• Medical Conditions Addressed: Severe arthritis, degenerative joint disease, or trauma affecting the big toe joint.
• Goals: Relieve pain, improve joint function, and enhance mobility in the big toe.

Indications

• Persistent pain in the big toe joint that doesn't respond to conservative treatments.
• Severe arthritis or deformity in the MTP joint.
• Limited range of motion or stiffness in the big toe causing difficulty in walking.

Preparation

• Pre-Procedure Instructions: Follow fasting guidelines, typically no food or drink 8-12 hours before surgery.
• Medication Adjustments: Temporarily discontinue blood thinners and other specific medications as advised by your doctor.
• Diagnostic Tests: X-rays, MRI, or CT scans may be needed to evaluate the extent of joint damage.

Procedure Description

1. Anesthesia: The procedure is performed under general anesthesia or regional anesthesia (nerve block).
2. Incision: A small incision is made over the top of the big toe to access the MTP joint.
3. Joint Preparation: The damaged cartilage and bone from the MTP joint are removed.
4. Implant Placement: An artificial implant, made of metal, plastic, or a combination, is inserted into the joint space.
5. Closure: The incision is closed with sutures, and a sterile dressing is applied.

Duration

The procedure typically takes about 1-2 hours.

Setting

• The surgery is usually performed in a hospital or an outpatient surgical center.

Personnel

• Surgeons: Orthopedic surgeon specialized in foot and ankle surgery.
• Nurses: Assisting with the procedure and patient care.
• Anesthesiologists: Administering anesthesia and monitoring the patient’s vital signs.

Risks and Complications

• Common Risks: Infection, bleeding, blood clots, and mild to moderate pain.
• Rare Complications: Implant failure, nerve damage, and ongoing pain despite the surgery.
• Management: Antimicrobial prophylaxis, pain management strategies, and close postoperative monitoring.

Benefits

• Significant pain relief and improved joint function.
• Enhanced mobility and stability in the big toe.
• Most patients notice improvement within a few weeks after surgery.

Recovery

• Post-Procedure Care: Keep the foot elevated and apply ice to reduce swelling. Follow wound care instructions.
• Expected Recovery Time: Generally, full recovery takes about 6-12 weeks. Limited weight-bearing on the foot initially, progressing to normal activity over several weeks.
• Follow-Up: Regular follow-up appointments to monitor healing and implant integration.

Alternatives

• Non-Surgical Treatments: Physical therapy, pain medications, corticosteroid injections, orthotic devices.
• Pros and Cons: Non-surgical treatments can delay the need for surgery but may not provide long-term relief. Surgery offers a more permanent solution but carries surgical risks.

Patient Experience

• During the Procedure: The patient will be under anesthesia and should not feel pain during the surgery.
• After the Procedure: Expect discomfort and swelling as anesthesia wears off, managed with pain medications. The medical team will provide instructions for movement and weight-bearing to promote healing.
