Clubfoot (CTEV) Treatment: Ponseti & Physiotherapy

What is Congenital Talipes Equinovarus (CTEV)?

Congenital Talipes Equinovarus (CTEV), commonly known as clubfoot, is a congenital condition where a baby's foot or feet turn inward and downward. If left untreated, clubfoot makes normal weight-bearing impossible, forcing the child to walk on the outer edges of their ankles as they grow, which leads to chronic pain and significant mobility limitations.

Today, the international standard of care is the Ponseti method, a non-surgical approach that combines gentle serial casting with targeted pediatric physiotherapy. This approach corrects the alignment of the foot bones and stretches tight soft tissues, allowing the child to develop typical walking patterns.

The Ponseti Method: Step-by-Step

Developed by Dr. Ignacio Ponseti, this method is highly effective, yielding success rates over 90% when started early in infancy. The treatment is divided into distinct phases:

| Phase | Goal | Typical Duration | Details | | :--- | :--- | :--- | :--- | | 1. Serial Casting | Correct the alignment of the tarsal bones through gentle manipulation and weekly plaster casts. | 4 to 6 weeks | The therapist/doctor gently stretches the foot toward the correct position and applies a long-leg cast to hold it. This is repeated weekly. | | 2. Tenotomy | Release the tight Achilles tendon to allow the heel to drop down into a neutral position. | Minor outpatient procedure | A small cut is made in the Achilles tendon under local anesthesia. A final cast is placed and worn for 3 weeks while the tendon heals and lengthens. | | 3. Bracing | Prevent the foot from pulling back into the clubfoot position as the child grows. | Up to 4 or 5 years | The child wears a special brace (boots attached to a metal bar). Compliance is critical during this phase to avoid relapse. |

The Role of Physiotherapy in CTEV Treatment

Physiotherapy works alongside the Ponseti method, focusing on flexibility, muscle activation, and helping the child meet gross motor milestones:

1. Maintaining Ankle Range of Motion

During the bracing phase, the ankle joints can become stiff. Physiotherapists teach parents passive stretching exercises to maintain ankle dorsiflexion (bending the foot upward). Stretching the Achilles tendon is particularly important to prevent the heel from pulling upward again.

2. Strengthening the Peroneal Muscles

In clubfoot, the muscles on the outer side of the leg (peroneal muscles) are often weak and stretched out, while the inner muscles are tight. Therapists use active-assisted exercises and sensory play to stimulate these outer muscles. Exercises like tickling the outer side of the foot to prompt the child to pull their foot outward are commonly used.

3. Promoting Gross Motor Milestones

Because the child wears a brace, they may need support adapting to milestones like rolling, sitting, and crawling. Physiotherapists design activities that help the child move dynamically while wearing the brace, ensuring they build core and hip strength.

4. Gait Re-education

As the child starts to stand and walk, the therapist monitors their alignment and foot contact. Gait training exercises focus on ensuring flat, even foot contact with the floor, preventing toe-walking, and developing an even step length.

Home Guidelines and Brace Compliance

Brace compliance is the most important factor in preventing clubfoot relapse. Parents can use these clinical tips to support the bracing phase:

1. Check for Skin Integrity: Inspect your child's feet daily for redness, blisters, or raw spots. Ensure the heel is seated firmly at the bottom of the boot to prevent friction.
2. Make the Brace Part of the Routine: Establish a consistent routine for putting on the brace during naps and bedtime. Keeping the brace on during these times is essential for long-term correction.
3. Perform Daily Stretches: Complete the stretching exercises recommended by your physical therapist during diaper changes or bath time. Regular stretching helps maintain joint flexibility.
4. Encourage Weight-Bearing: Once your child is ready to stand, encourage them to stand on flat surfaces. Weight-bearing helps stretch the calf muscles naturally and strengthens the bones of the foot.
