Talipes (Club Foot )

Symptoms: 

A clubfoot is turned sharply inward. This makes the heel appear to be on the outside of the foot and the toes point inward toward the other foot. In severe cases, the foot may appear to be upside down.

Children with clubfoot wobble when they walk. They often walk on the outside of the affected foot to maintain balance.

Although clubfoot looks uncomfortable, it does not cause pain or discomfort. Children with untreated clubfoot may have a smaller calf on the affected leg. This leg may also be slightly shorter than the unaffected leg.

Tests to diagnose: 

The disorder is identified during a physical examination. A foot x-ray may be done.

Treatment: 

The goal of treatment is to obtain a functional, pain-free foot that enables standing and walking with the sole of the foot flat on the ground.

Nonsurgical Treatment

The initial treatment of clubfoot is nonsurgical, regardless of how severe the deformity is.

  • Ponseti method

The most widely used technique in North America and throughout the world is the Ponseti method, which uses gentle stretching and casting to gradually correct the deformity

In the Ponseti method, long-leg plaster casts are applied after the feet are correctly positioned.

Treatment should ideally begin shortly after birth, but older babies have also been treated successfully with the Ponseti method. Elements of the method include:

  • Manipulation and casting

Your baby's foot is gently stretched and manipulated into a corrected position and held in place with a long-leg cast (toes to thigh). Each week this process of stretching, re-positioning, and casting is repeated until the foot is largely improved. For most infants, this improvement takes about 6 to 8 weeks.

  • Achilles tenotomy

After the manipulation and casting period, most babies will require a minor procedure to release continued tightness in the Achilles tendon (heel cord). During this quick procedure (called a tenotomy), your doctor will use a very thin instrument to cut the tendon. The cut is very small and does not require stitches. A new cast will be applied to the leg to protect the tendon as it heals. This usually takes about 3 weeks. By the time the cast is removed, the Achilles tendon has regrown to a proper, longer length, and the clubfoot has been fully corrected.

  • Bracing

Even after successful correction with casting, clubfeet have a natural tendency to recur. To ensure that the foot will permanently stay in the correct position, your baby will need to wear a brace (commonly called "boots and bar") for a few years. The brace keeps the foot at the proper angle to maintain the correction. This bracing program can be demanding for parents and families, but is essential to prevent relapses.

For the first 3 months, your baby will wear the brace essentially full-time (23 hours a day). Your doctor will gradually decrease the time in the brace to just overnight and nap time (about 12 to 14 hours per day). Most children will follow this bracing regimen for 3 to 4 years.

There are several different types of braces โ€” all of which consist of shoes, sandals, or custom-made footwear attached to the ends of a bar. The bar can be solid (both legs move together) or dynamic (each leg moves independently). Your doctor will talk with you about the type of brace that would best meet your baby's needs.

Babies might be fussy during the first few days of wearing a brace and will need time to adjust. More information about helping your baby adjust to bracing is provided at the end of this article in the section titled "Helpful Tips for Bracewear."

  • Considerations of the Ponseti method

 The Ponseti method has proven extremely effective for many children. It does, however, require the family to be highly committed to applying the braces properly every day. If the brace is not worn as prescribed, the clubfoot will recur.

A small percentage of children develop relapses despite proper bracing. If the child's foot slips out of the boot on a regular basis, it may be the first sign of a mild recurrence of the deformity. If addressed promptly, this can usually be corrected with a few serial casts and possibly a minor surgery.

In addition, applying the Ponseti method correctly requires training, experience, and practice. Be sure to ask your pediatrician for a referral to an orthopaedic surgeon with expertise in the nonsurgical correction of clubfoot.

  • French method

Another nonsurgical method to correct clubfoot incorporates stretching, mobilization, and taping. The French method โ€” also called the functional or physical therapy method โ€” is typically directed by a physical therapist who has specialized training and experience.

Like the Ponseti method, the French method is begun soon after birth and requires family involvement. Each day, the baby's foot must be stretched and manipulated, then taped to maintain the range of motion gained by the manipulation. After taping, a plastic splint is put on over the tape to maintain the improved range of motion.

This method requires approximately three visits to the physical therapist each week. Because this is a daily regimen, the therapist will teach the parents how to do it correctly at home.

After 3 months, most babies have significant improvement in foot position, and visits to the physical therapist are required less often. Like children treated with the Ponseti method, babies treated with the French method commonly require an Achilles tenotomy to improve dorsiflexion of the ankle.To prevent recurrence of the clubfoot, the daily regimen of stretching, taping, and splinting must be continued by the family until the child is 2 to 3 years old.

Surgical Treatment

Although many cases of clubfoot are successfully corrected with nonsurgical methods, sometimes the deformity cannot be fully corrected or it returns, often because parents have difficulty following the treatment program. In addition, some infants have very severe deformities that do not respond to stretching. When this happens, surgery may be needed to adjust the tendons, ligaments, and joints in the foot and ankle.

Because surgery typically results in a stiffer foot, particularly as a child grows, every effort is made to correct the deformity as much as possible through nonsurgical methods. Even an infant with severe deformities or clubfeet associated with neuromuscular conditions can improve without surgery. If a child's foot has been partially corrected with stretching and casting, then the surgery required to fully correct the clubfoot will be less extensive.

  • Less extensive surgery will target only those tendons and joints that are contributing to the deformity. In many cases, this involves releasing the Achilles tendon at the back of the ankle or moving the tendon that travels from the front of the ankle to the inside of the midfoot (this procedure is called an anterior tibial tendon transfer).
  • Major reconstructive surgery for clubfoot involves extensive release of multiple soft tissue structures of the foot. Once the correction is achieved, the joints of the foot are usually stabilized with pins and a long-leg cast while the soft tissue heals.After 4 to 6 weeks, the doctor will remove the pins and cast, and typically apply a short-leg cast, which is worn for an additional 4 weeks. After the last cast is removed, it is still possible for the muscles in your child's foot to try to return to the clubfoot position, so special shoes or braces will likely be used for up to a year or more after surgery.The most common complications of extensive soft tissue release are overcorrection of the deformity, stiffness, and pain.
