Clubfoot, or congenital talipes equinovarus (CTEV), is a structural deformity where a baby is born with one or both feet twisted inward. This condition can make walking difficult if left untreated, necessitating early intervention. While non-surgical methods, such as the Ponseti method (serial casting and bracing), are often the first line of treatment, some cases require surgical intervention to achieve optimal correction.
When is Surgery Necessary for Clubfoot?
Surgery for clubfoot is considered when:
- Non-surgical treatments, such as casting or bracing, fail to correct the deformity.
- The child has a severe form of clubfoot with rigid tendons and joints.
- There is a relapse after initial conservative treatment.
- The foot does not achieve adequate flexibility and function for walking.
Surgical correction is usually recommended after the child reaches 9 to 12 months of age but may be performed earlier in severe cases.
Types of Pediatric Clubfoot Surgeries
1. Soft Tissue Release Surgery
This is the most common surgical procedure for clubfoot, where tendons, ligaments, and joint capsules are lengthened or repositioned to improve foot alignment. The Achilles tendon is often lengthened to reduce tightness, allowing better dorsiflexion (the upward movement of the foot).
2. Posteromedial Release Surgery (PMR)
This procedure involves making incisions around the foot and ankle to lengthen tendons, reposition ligaments, and adjust the foot bones. It is recommended for more severe clubfoot cases that have not responded to non-surgical treatments.
3. Osteotomy (Bone Surgery)
In older children or severe cases, a bone-cutting procedure (osteotomy) may be necessary to realign the foot. This involves reshaping the foot bones and securing them with pins or screws.
4. Joint Fusion Surgery (Arthrodesis)
For children with clubfoot relapse or those who did not undergo early correction, joint fusion surgery may be needed to stabilize the foot and prevent deformity progression.
5. Minimally Invasive Surgery (Percutaneous Achilles Tenotomy)
This is a minor surgical procedure often performed alongside the Ponseti method. It involves making a small incision to release the Achilles tendon, allowing better foot positioning without extensive surgery.
What to Expect Before Surgery
1. Preoperative Evaluation
Before scheduling surgery, a pediatric orthopedic specialist will assess the child’s condition using:
- Physical Examination – Checking foot flexibility, muscle tightness, and overall leg function.
- X-rays or Imaging – To determine bone positioning and plan the best surgical approach.
- Medical History Review – Ensuring the child is healthy enough for anesthesia and surgery.
2. Preparing for Surgery
- Parents may be advised to stop certain medications, such as blood thinners, before the procedure.
- Fasting is required for a few hours before surgery to prevent anesthesia complications.
- The surgical team will explain post-operative care, including immobilization and rehabilitation.
The Surgical Procedure
The duration of clubfoot surgery varies depending on the complexity but typically lasts 2 to 3 hours. The child will be under general anesthesia to ensure a painless experience.
Surgical Steps
- Incision Placement – Small incisions are made along the foot to access tight tendons and ligaments.
- Tendon Lengthening and Repositioning – The surgeon lengthens or repositions the Achilles tendon and other affected structures.
- Bone Realignment (if necessary) – In cases requiring bone adjustment, small cuts are made to reshape foot bones.
- Fixation – Pins or sutures may be used to hold the corrected foot position.
- Wound Closure and Casting – The incisions are closed with sutures, and the foot is placed in a cast to maintain correction.
Post-Surgical Recovery and Rehabilitation
1. Hospital Stay
Most children stay in the hospital for 1 to 3 days for monitoring. Pain management includes mild painkillers or anti-inflammatory medications.
2. Cast and Bracing
- A post-surgical cast is applied for 4 to 6 weeks to maintain foot positioning.
- Once the cast is removed, bracing therapy continues to prevent recurrence, often for several months or even years.
3. Physical Therapy and Rehabilitation
- Early Movement – Encouraged once the cast is removed to regain mobility.
- Stretching Exercises – Help prevent muscle stiffness and maintain foot flexibility.
- Gait Training – For older children learning to walk after surgery.
Potential Risks and Complications
While pediatric clubfoot surgery is generally safe, there are potential risks, including:
- Infection – Prevented with proper wound care and antibiotics.
- Recurrence of Clubfoot – Some cases require additional corrective procedures.
- Scarring and Stiffness – May occur in more extensive surgeries.
- Uneven Leg Length – Rare but can affect walking patterns.
Long-Term Outlook and Success Rates
With proper surgical intervention and post-operative care, clubfoot surgery has a success rate of over 90%. Many children achieve near-normal foot function, enabling them to walk, run, and participate in regular activities. However, long-term follow-ups are essential to monitor foot development and prevent recurrence.
Choosing the Right Pediatric Surgeon and Facility
When considering pediatric surgery for clubfoot, parents should:
- Look for Specialized Pediatric Orthopedic Surgeons with experience in clubfoot correction.
- Ensure Advanced Pediatric Anesthesia and Post-Operative Care to minimize risks.
- Check for Comprehensive Rehabilitation Services, including physical therapy and long-term follow-ups.
- Consider the Hospital’s Success Rate and Patient Outcomes in treating clubfoot.
Pediatric surgery for clubfoot is a well-established and effective treatment for children with severe or treatment-resistant cases. While the journey involves surgery, post-operative care, and long-term bracing, the end result is significantly improved mobility and quality of life. Parents should work closely with their child's medical team to ensure the best possible outcome, allowing their child to walk, play, and grow with confidence.
