Singapore Clubfoot Children Specialist
Clubfoot is a congenital condition that affects newborn infants. The medical term for clubfoot is Congenital Talipes Equinovarus. This condition has been described in medical literature since the ancient Egyptians. Congenital means that the condition is present at birth and occurred during fetal development. The condition is not rare and the incidence varies widely among different races. In the caucasian population, about one in a thousand infants are born with a clubfoot. In Japan, the numbers are one in two thousand and in some races in the South Pacific it can be as high as seven infants in one thousand who are born with a clubfoot. The condition affects both feet in about half of the infants born with clubfoot. Clubfoot affects twice as many males as females.
Anatomy of foot
What part of the foot is affected?
One interesting finding is that the calf muscles on the leg with the clubfoot are smaller than normal. If the clubfoot only affects one foot, the calf muscles on this leg will always remain smaller than the opposite side.
Causes of Clubfoot
How does this problem develop?
During the nine months of pregnancy, the fetus undergoes remarkable changes. In the skeleton, these changes include the separation of each individual bone in the body from one mass of bone material. In some cases, this process is flawed. A clubfoot occurs when this type of failure of separation occurs in the tarsal bones of the foot.
Until recently, most experts believed that the deformity was due to the foot being stuck in the wrong position in the womb. As development progressed, the foot could not grow normally because it was turned under and held in that position. Today, most information suggests that clubfoot is hereditary, meaning that it runs in families. It is not clear what genetic defect causes the problem. It is not known yet whether the defect affects the development of the muscles, blood vessels, or bones of the foot.

Diagnosis of Clubfoot
How do doctors identify the problem?
The history and physical examination make the diagnosis of clubfoot. The appearance alone is usually enough to make the diagnosis. A complete examination of the newborn is critical, since there are other genetic conditions that are associated with clubfeet. Your pediatrician will perform a complete evaluation to make sure there are no other congenital conditions to be concerned with.
A clubfoot can be diagnosed before birth using ultrasound. Many women have routine ultrasound test to assess the status of the pregnancy. When a clubfoot is found, there is no treatment currently available before birth. Because clubfoot is associated with other serious congenital and genetic abnormalities, the obstetrician may recommend amniocentesis to look for genetic problems in the fetus. An amniocentesis is a test where a needle is inserted into the uterus and a small amount of fluid removed. This fluid is sent to the lab for analysis. If evidence for serious genetic or congenital anomalies are found, then the option of terminating the pregnancy exists.
X-rays are helpful in determining the severity of the condition. This information may become important later in trying to decide what treatment is best to recommend. Usually, no other imaging studies are needed.
Treatment of Clubfoot
What treatment options are available?
Treatment for clubfoot usually starts at birth. Treatment in the majority of infants will require both non-surgical treatment and surgery.
The most commonly used treatment in the newborn and infant is manipulation and casting. This is started as soon as possible. The foot is manipulated to stretch and loosen the tight structures. The foot is then placed in a cast to hold it in a corrected position. This is repeated every one or two weeks until the deformity is corrected or surgery is performed.
As any parent knows, the newborn grows rapidly after birth. The technique of manipulation and casting the foot is used to guide the growth of the foot towards the normal alignment. Without this guidance, the foot will remain deformed and may actually get worse. The greatest chance for correction of deformity occurs early in life when there is so much growth occurring.
There have been many different techniques proposed for the way the foot is manipulated and the way the casts are applied. Treatment of the infant with clubfoot is definitely one of the arts of medicine. Successful treatment requires patience and attention to detail.
The success of treatment of clubfoot by manipulation and casting alone varies greatly. The majority of infants will eventually require surgery. But, the manipulation and casting begins the process of guiding the foot towards a more normal form. In the infant that eventually needs surgery, the manipulation and casting are still required to obtain as much correction as possible prior to the surgery.
When it is clear that manipulation and casting alone will not result in success, surgery will be recommended by your surgeon. The main question is when to perform the surgery. The earlier the surgery is performed, the more growth remains in the foot. The more growth remaining, the more the deformity can be corrected. But, a smaller foot is much harder to operate on effectively. The surgery is much harder and the risk of damage to the nerves, blood vessels, and bones is much higher.
Most surgeons recommend waiting until the foot is about eight cm (three inches) long. This usually occurs when the infant is about nine months old. Most surgeons agree that it is ideal to have the surgery over and healed before the infant starts to try and walk. Surgery performed at nine months usually will accomplish this as well.
What should be expected from treatment?
All treatment, both surgical or non-surgical, is designed to give the child a foot that can be placed flat on the floor. The foot will never be normal, but treatment can provide a very functional foot that can be used for walking without pain. If surgery is required, the goal is to have the foot healed by the time the child is starting to walk.
After surgery for clubfoot, a large bandage is applied to the foot. Some type of cast or brace may also be used. The child will probably need to wear some type of brace for several months – and maybe even years after the surgery – but ideally, the treatment should not interfere with the normal developmental milestones. Once the surgery is over, mother nature takes over. Weightbearing will help guide the growth in the foot towards a more functional orientation where the sole of the foot can be placed flat on the floor.
What can go wrong?
As with any treatment, complications can result from both conservative and surgical treatment of clubfoot. Failure of manipulation and casting to result in a successful outcome is not a complication. The majority of patients will not be treated successfully with non-surgical treatment alone.
Several complications are possible both during and after surgery. Wound problems may occur after surgery due to abnormal swelling or pressure from the cast. When the foot is markedly deformed, correction of the deformity may stretch the skin so tight that the blood supply is compromised. This may result in a small section of the skin actually dying. This normally heals with time and only rarely does this require a skin graft.
Infection can occur following any type of surgery. A wound infection can occur after clubfoot surgery. This may require additional surgery to drain the infection and antibiotics to treat the infection.
The infant foot is very small. The structures are very difficult to see even using magnifying glasses. Blood vessels and nerves may be damaged or cut during the operation. The bones of the infant foot are mostly made of cartilage. This material can be damaged, resulting in deformities of these bones. This damage usually corrects itself with growth.
Up to half of all patients undergoing clubfoot surgery will require at least one additional surgical procedure later in life.
