Clubfoot is a congenital foot and ankle deformity in which the foot is positioned inward and downward. The deformity is not simply the result of the foot being turned in one direction. It involves several components occurring together: the forefoot turns inward, the heel tilts inward, the middle of the foot develops a high arch, and the ankle remains pointed downward.
At birth, the affected foot is usually visibly different from the opposite side. The foot may appear smaller, the calf may be thinner, and the ankle and heel may be difficult to bring into a normal position. In many infants, the deformity is flexible enough to be corrected gradually with treatment. In more severe cases, the foot can be relatively rigid.
The appearance can be concerning for parents, but clubfoot is highly treatable, particularly when treatment begins early.
Anatomy
Clubfoot results from abnormal positioning and tightness of the bones, joints, tendons, ligaments, and surrounding soft tissues of the foot and ankle. The talus is abnormally positioned within the ankle and midfoot, while the calcaneus and other bones are rotated and displaced in relation to one another.
The Achilles tendon and other structures along the back and inside of the ankle are commonly shortened or contracted. These changes prevent the foot from being brought into a normal plantigrade position.
The goal of treatment is not simply to make the foot look straighter. We want to restore a functional, flexible foot that can accommodate normal walking and activity as the child grows.
Symptoms
Clubfoot is usually identified at birth and may involve one or both feet. Both feet are affected in approximately half of cases. It occurs more often in boys than girls.
Most cases are classified as idiopathic, meaning there is no single identifiable underlying cause. Some children, however, have clubfoot associated with neuromuscular or genetic conditions. These cases can behave differently from idiopathic clubfoot and may be more rigid or more difficult to maintain in correction.
The presence of clubfoot does not mean that a child will have problems with intelligence or development. It is primarily a structural problem involving the foot and ankle.
Evaluation
Clubfoot can often be diagnosed by examining the foot. We look at the position of the forefoot, arch, heel, and ankle and assess how flexible the deformity is. We also compare the affected foot with the opposite side and examine the calf and overall lower-extremity alignment.
Prenatal ultrasound can sometimes identify clubfoot before birth. After delivery, routine imaging is often not necessary for a straightforward newborn clubfoot because the diagnosis is primarily clinical. X-rays, MRI, or CT may become useful in older children, recurrent cases, complex deformities, or situations in which the underlying anatomy is unclear.
One of the most important distinctions is whether the foot is flexible or rigid. A flexible deformity generally responds much better to gentle manipulation and casting, while a rigid or recurrent deformity may require additional treatment.
Treatment Protocol
The Pirani score is one system used to describe the severity of clubfoot. It evaluates specific physical findings and produces a score that helps establish a baseline and monitor correction during treatment.
We use severity as one piece of the decision-making process rather than treating a number by itself. The child’s age, flexibility of the foot, associated medical conditions, previous treatment, and response to correction all influence the treatment plan.
A severe score does not automatically mean that a child will need major surgery. Many infants with significant deformity can still achieve excellent correction with early nonsurgical treatment.
Treatment
For idiopathic clubfoot, the Ponseti method is the foundation of treatment. The foot is gently manipulated into a progressively better position and placed in a cast. The casts are changed regularly as the deformity corrects.
The sequence of correction addresses the major components of the deformity rather than forcing the entire foot into position at once. Most children require several casts before the foot reaches the desired alignment.
When the ankle remains pointed downward after the other components have been corrected, an Achilles tenotomy may be necessary. This is a small procedure used to release the tight Achilles tendon and allow the ankle to reach a plantigrade position. It is commonly performed as part of the Ponseti treatment process rather than being considered a failure of casting.
Bracing
Correcting the foot is only the first part of treatment. Maintaining that correction is equally important.
After casting, the child wears a foot-abduction brace to hold the feet in the corrected position. The brace is initially worn for most of the day and is then transitioned to use during naps and nighttime for several years.
The bracing period can be challenging for families, but it is critical because clubfoot has a tendency to recur as the child grows. Recurrence is particularly associated with difficulty maintaining the recommended brace schedule.
Regular follow-up allows us to identify loss of correction early, when it can often be addressed more easily.
Additional Surgery
Most idiopathic clubfeet can be managed without major reconstructive surgery. Additional procedures are considered when the deformity is rigid, has returned after previous treatment, or is associated with a condition that makes correction more difficult.
The procedure depends on the child’s age and the specific deformity. Options may include additional soft-tissue procedures, tendon transfer, or bone realignment procedures for older children with fixed deformity.
The goal remains the same: restore a plantigrade, functional foot while preserving as much motion as possible. Extensive surgery is not the starting point for a typical newborn clubfoot.
Recovery
Early treatment generally produces substantial improvement over the first several weeks. The casting phase is followed by bracing, which is much longer than the initial correction period.
Families should understand that the treatment does not end when the casts come off. The brace and follow-up schedule are part of the correction process. Children can gradually return to normal activities as their treatment progresses, and most successfully treated children are able to walk, run, play, and participate in routine childhood activities.
The treated foot may remain somewhat smaller than the opposite foot, and the calf may remain thinner. These differences do not necessarily prevent normal function.
Recurrence
Clubfoot can recur even after an initially successful correction. Recurrence may appear as the foot beginning to turn inward again, the arch becoming more pronounced, or the ankle losing its ability to reach a plantigrade position.
The risk is one reason long-term follow-up matters. When recurrence is recognized early, treatment may involve renewed casting, adjustment of the brace program, or a relatively limited procedure. More established recurrence can require additional reconstruction.
A recurrence does not mean that the original treatment failed. Clubfoot is a deformity that can change as the child grows, and treatment may need to adapt accordingly.
Outcome
A good result is not simply a straight-looking foot on an X-ray. The meaningful goal is a plantigrade, flexible, functional foot that allows the child to walk and participate in normal activities without significant pain or limitation.
With early and consistent treatment, most children with idiopathic clubfoot achieve excellent functional outcomes. The Ponseti method has made it possible to correct many feet that historically would have required extensive surgery.
The most important factors are recognizing the deformity early, obtaining appropriate correction, maintaining that correction with bracing, and continuing follow-up as the child grows.
