Club foot
Encyclopedia
A club foot, or congenital talipes equinovarus (CTEV), is a congenital deformity involving one foot or both. The affected foot appears rotated internally at the ankle. TEV is classified into 2 groups: Postural TEV or Structural TEV.

Without treatment, persons afflicted often appear to walk on their ankles, or on the sides of their feet. It is a common birth defect, occurring in about one in every 1,000 live births. Approximately 50% of cases of clubfoot are bilateral. In most cases it is an isolated dysmelia

Prenatal Screening

Screening for club foot prenatally is a debatable topic. However, this is commonly done as it is easily identified using a ultrasound scan. Most fetuses undergo a 20 weeks gestation fetal abnormality scan in which club foot is one of the abnormalities that can be picked up. Some doctors have argued that club foot may occasionally be associated with a syndromic disease and should therefore be screened. If no syndromic association is found prenatally, most fetuses with club foot are born and can live a normal life with medical treatment.

. Foot manipulations usually begin within two weeks of birth. Even with successful treatment, when only one side is affected, that foot may be smaller than the other, and often that calf, as well.

Extensive surgery of the soft tissue or bone is not usually necessary to treat clubfoot; however, there are two minimal surgeries that may be required:
  1. Tenotomy

  2. Anterior Tibial Tendon Transfer (needed in 20% of cases) – where the tendon is moved from the first ray (toe) to the third ray in order to release the inward traction on the foot.

Of course, each case is different, but in most cases extensive surgery is not needed to treat clubfoot. Extensive surgery may lead to scar tissue developing inside the child's foot. The scarring may result in functional, growth and aesthetic problems in the foot because the scarred tissue will interfere with the normal development of the appendage. A child who has extensive surgery may require on average two additional surgeries to correct the issues presented above.

In stretching and casting therapy the doctor changes the cast multiple times over a few weeks, gradually stretching tendons until the foot is in the correct position of external rotation. The heel cord is released (percutaneous tenotomy) and another cast is put on, which is removed after three weeks. To avoid relapse a corrective brace is worn for a gradually reducing time until it is only at night up to four years of age.

Non-surgical treatment and the Ponseti Method

Treatment for clubfoot should begin almost immediately to have the best chance for a successful outcome without the need for surgery. Over the past 10 to 15 years, more and more success has been achieved in correcting clubfeet without the need for surgery. The clubfoot treatment method that is becoming the standard in the U.S. and worldwide is known as the Ponseti Method

The Ponseti method, if correctly done, is successful in >95% of cases in correcting clubfeet using non- or minimal-surgical techniques. Typical clubfoot cases usually require 5 casts over 4 weeks. Atypical clubfeet and complex clubfeet may require a larger number of casts. Approximately 80% of infants require an Achilles tenotomy (microscopic incision in the tendon requiring only local anesthetic and no stitches) performed in a clinic toward the end of the serial casting.

 have been studying the effectiveness of both the Ponseti casting method and the French functional (physical therapy) method of stretching, massaging and taping and comparing the results with patients who have undergone surgery. Results of these studies have been presented at national and international conferences, such as the Pediatric Orthopaedic Society of North America annual meeting, the International Clubfoot Symposium, Brandon Carrell Visiting Professorship and the American Academy of Orthopaedic Surgeons annual meeting, and have been published in the Journal of Pediatric Orthopaedics.

After correction has been achieved, maintenance of correction may require the full-time (23 hours per day) use of a splint—also known as a foot abduction brace (FAB)—on both feet, regardless of whether the TEV is on one side or both, for several weeks after treatment. Part-time use of a brace (generally at night, usually 12 hours per day) is frequently prescribed for up to 4 years. Without the parents' participation, the clubfoot will almost certainly recur, because the muscles around the foot can pull it back into the abnormal position. Approximately 20% of infants successfully treated with the Ponseti casting method may require a surgical tendon transfer after two years of age. While this requires a general anesthetic, it is a relatively minor surgery that corrects a persistent muscle imbalance while avoiding disturbance to the joints of the foot.

The developer of the Ponseti Method, Dr Ignacio Ponseti, was still treating children with clubfeet (including complex/atypical clubfeet and failed treatment clubfeet) at the University of Iowa Hospitals and Clinics well into his 90s. He was assisted by Dr Jose Morcuende, president of the Ponseti International Association.

The long-term outlook for children who experienced the Ponseti Method treatment is comparable to that of non-affected children.

Botox is also being used as an alternative to surgery. Botox is the trade name for Botulinum Toxin type A. a chemical that acts on the nerves that control the muscle. It causes some paralysis(weakening) of the muscle by preventing muscle contractions (tightening). As part of the treatment for clubfoot, Botox is injected into the child’s calf muscle. In about 1 week the Botox weakens the Achilles tendon. This allows the foot to be turned into a normal position, over a period of 4–6 weeks, without surgery.

The weakness from a Botox injection usually lasts from 3–6 months. (Unlike surgery it has no lasting effect). Most club feet can be corrected with just one Botox injection. It is possible to do another if it is needed. There is no scar or lasting damage.

Surgical treatment

On occasion, stretching, casting and bracing are not enough to correct a baby's clubfoot. Surgery may be needed to adjust the tendons, ligaments and joints in the foot/ankle. Usually done at 9 to 12 months of age, surgery usually corrects all clubfoot deformities at the same time. After surgery, a cast holds the clubfoot still while it heals. It is still possible for the muscles in the child's foot to try to return to the clubfoot position, and special shoes or braces will likely be used for up to a year or more after surgery. Surgery will likely result in a stiffer foot than nonsurgical treatment, particularly over time.

Without any treatment, a child's clubfoot will result in severe functional disability, however with treatment, the child should have a nearly normal foot. He or she can run and play without pain and wear normal shoes. The corrected clubfoot will still not be perfect, however; a clubfoot usually stays 1 to 1½ sizes smaller and somewhat less mobile than a normal foot. The calf muscles in a leg with a clubfoot will also stay smaller.

Long-term studies of adults with post-club feet, especially those with substantial numbers of surgeries, may not fair as well in the long term, according to Dobbs, et. al., A percentage of adults may require additional surgeries as they age, though there is some dispute as to the effectiveness of such surgeries, in light of the prevalence of scar tissue present from earlier surgeries.

 work on the hooves can lessen the severity of many cases, and in certain circumstances surgery may be beneficial. The visible outward appearance of a club foot has different possible origins that include a genetic predisposition to the condition, a congenital defect formed while the animal is in the womb, or problems with diet and bone development during the early post-natal period. Certain horse breeds appear to be more predisposed to the condition than others, but research has yet to identify the genes involved.

A grading scale exists to assess the severity of club feet, which are caused by a deep digital flexor contraction syndrome. When the muscle fibers of the upper leg's deep ditigal flexor muscle contract excessively, this affects the tendon of the same name that comes off of this muscle group and attaches at the bottom of the coffin bone.
