Club Foot in Newborns: Early Detection & Ponseti Method Treatment

The First Words Every Parent Needs to Hear

You have just had your baby. The midwife or paediatrician has examined the newborn, and they tell you that one (or both) of your baby's feet is turned inward — this is club foot. In that moment, a storm of questions, fears, and grief for the imagined "perfect" delivery floods in. Will my child walk normally? Will they be in pain? Will they need major surgery?

Here is what I tell every parent who sits in my clinic with a club foot diagnosis: this is one of the most treatable congenital conditions in orthopaedics. The outcomes, when treatment begins early and is done correctly, are excellent. Children treated with the Ponseti method in the first weeks of life grow up to be athletes, dancers, soldiers, and farmers — indistinguishable from their peers in physical ability.

But timing genuinely matters. This is the one condition where acting immediately — not "waiting to see" — gives your child the best possible outcome.

"A baby's joints and tendons are at their most malleable in the first weeks of life. The same correction that takes 6 weeks in a newborn can take months in a 3-year-old and may require extensive surgery in an older child. Start early."

What is Club Foot (CTEV)?

The medical term is Congenital Talipes Equinovarus — which sounds intimidating but describes exactly what you see:

• Talipes — refers to the ankle (talus = ankle, pes = foot)
• Equinus — the foot is pointed downward (like a horse's hoof — equine)
• Varus — the foot is turned inward
• Congenital — present at birth

Together, the foot is twisted inward, the sole faces inward and upward, and the heel is pulled up. It can affect one foot (unilateral — more common) or both feet (bilateral). Globally, it occurs in approximately 1 in 1,000 births, making it one of the most common congenital musculoskeletal conditions. In India, with over 25 million births annually, approximately 25,000–35,000 babies are born with club foot every year.

What Causes Club Foot?

In most cases, the cause is unknown — this is called idiopathic club foot, and it accounts for approximately 80% of cases. Despite decades of research, no single gene or environmental factor has been identified as the definitive cause.

Several factors are associated with higher risk:

• Family history — if a parent or sibling has club foot, the risk in subsequent children is approximately 3–4 times higher
• Male sex — boys are affected approximately twice as frequently as girls
• Oligohydramnios — reduced amniotic fluid may restrict foot positioning in the womb
• Maternal smoking — some studies suggest a modest increased risk

In approximately 20% of cases, club foot is syndromic — occurring as part of a broader condition such as:

• Spina bifida (myelomeningocele) — club foot in this context requires a different, more complex treatment approach
• Arthrogryposis — a condition of multiple joint contractures; the most challenging form of club foot to treat
• Chromosomal anomalies

Idiopathic club foot responds excellently to the Ponseti method. Syndromic club foot requires specialist evaluation and often more intensive treatment, but can still achieve good functional outcomes.

The Ponseti Method — The Gold Standard Treatment

Developed by Dr. Ignacio Ponseti at the University of Iowa in the 1950s, the Ponseti method is now the worldwide standard of care for idiopathic club foot. Despite being decades old, it was only widely adopted globally in the 1990s and 2000s — and it transformed outcomes for millions of children by largely eliminating the need for major reconstructive surgery.

How It Works

The method is based on the insight that the newborn foot, with its largely cartilaginous structure and elastic ligaments, can be gradually and gently manipulated into a correct position if this is done systematically and in the right sequence of corrections.

1. Assessment — the severity of the deformity is scored (typically using the Pirani score) to guide treatment planning
2. Serial manipulation and casting — the orthopaedic surgeon gently manipulates the foot by hand, correcting the deformity in a specific sequence (cavus first, then adductus, then varus, then equinus — the CAVE sequence), and applies a plaster cast holding the corrected position. This is repeated weekly.
3. Number of casts — typically 5–7 casts over 5–7 weeks, though complex cases may require more
4. Percutaneous Achilles tenotomy — approximately 80% of children require a minor procedure to release the tight Achilles tendon as the final step before the foot can be held in the correct position. This is performed under local anaesthetic as a day procedure; a tiny nick is made in the tendon, which heals fully in 3 weeks within a final cast.
5. Foot Abduction Brace (FAB) — after casting, the child wears a boots-and-bar brace to maintain the correction and prevent relapse. This is the most critical and most often neglected phase.

The Bracing Phase — Non-Negotiable

The brace (also called a Denis Browne bar or Steenbeck brace) holds both feet turned outward at a specific angle. The bracing schedule is:

• First 3 months — brace worn 23 hours a day (removing only for bathing and exercises)
• Next 4 years (approximately) — brace worn during all sleep periods (naps and night) — typically 12–14 hours per day

The relapse rate without adequate bracing is 80%. With consistent bracing as prescribed, relapse rates fall to under 10%. The brace is the most important determinant of long-term outcome after the initial correction — and it is entirely in the parents' hands.

Why Timing Matters So Much

Newborn cartilage and connective tissue are at peak malleability — they respond to gentle mechanical forces remarkably quickly. The same correction that takes 5–6 casts in a 2-week-old may take 10–12 casts in a 3-month-old, and may not be fully achievable with casting alone in a child over 12 months old.

As children age without treatment, the soft tissue contractures become firmer, the bones begin to ossify (harden) into the deformed position, and the deformity becomes increasingly fixed. Older children may still benefit significantly from the Ponseti method, but results are less predictable and more supplementary surgery is often needed.

Ideally, treatment begins in the first week of life. Any delay beyond 3 months significantly complicates treatment and outcomes.

What if Treatment is Delayed?

Children who do not receive early Ponseti treatment may still achieve good outcomes with surgical correction, though this involves longer recovery and more extensive scarring:

• Posteromedial release (PMR) — the traditional surgical approach; releases multiple tight structures around the ankle under general anaesthesia. Effective but associated with more stiffness and scarring than the Ponseti method.
• Ilizarov frame distraction — for complex neglected cases with severe fixed deformity; a slow, gradual correction over weeks using an external fixator
• Osteotomy — for older children with bony deformity

Even in older children with neglected club foot, meaningful functional improvement is achievable — it is never truly "too late" to treat, though the process becomes more complex.

Dr. Arpit Maurya's Expertise in Congenital Orthopaedics

Dr. Arpit Maurya specialises in congenital bone and joint disorders in children, including:

• CTEV (Club Foot) — Ponseti method casting, tenotomy, and brace management
• CDH (Congenital Dislocation of Hip) — another important congenital condition requiring early detection and treatment; the hip joint is partially or completely dislocated from birth. Early Pavlik harness treatment gives excellent results.
• Developmental Dysplasia of the Hip (DDH) — a spectrum including mild hip instability through to complete dislocation
• Other congenital limb conditions requiring orthopaedic evaluation and management

After Treatment — What to Expect

Physical Activity Milestones

Children treated by Ponseti develop at essentially the same pace as other children:

• Sitting, crawling, and pulling to stand at normal developmental ages
• First steps usually taken at the normal developmental window of 10–14 months
• Running, climbing, and jumping develop normally throughout early childhood
• Sport participation is actively encouraged from school age onwards

Warning Signs of Relapse

Even with excellent initial treatment, a small percentage of club feet relapse — particularly if bracing compliance was inconsistent. Parents should watch for:

• The foot beginning to turn inward again
• Progressive supination (sole turning inward) when walking
• Walking on the outer border of the foot
• Difficulty fitting into normal footwear

If any of these are noticed, an early review appointment should be arranged. Relapse detected early can often be treated with a short additional course of casting — delaying contact until the deformity is severe makes management more complex.

Long-Term Outcomes

Long-term follow-up studies — tracking children treated by Ponseti into their 20s and 30s — show that the vast majority are physically active, have no significant functional limitations, and do not have higher rates of arthritis than the general population. The treated foot is typically a half-size smaller than the other foot, which is cosmetically minor and functionally irrelevant. Most patients require no special footwear in adulthood.
