What Causes Clubfoot During Pregnancy?

26 February 2026 · By Ben Restall · 15 min read

If you have just heard the words “possible talipes” at a scan, it is completely normal to feel shocked, guilty, and desperate to understand what causes clubfoot during pregnancy. I remember that immediate rush of questions: what did I do, what should I do now, and will my baby be okay? This guide gives evidence-based answers in plain UK-parent language, with practical next steps and emotional reassurance.

Why this question feels so heavy

When parents search for what causes clubfoot during pregnancy, they are usually not just looking for biology. They are often trying to answer a painful emotional question: did i cause my baby clubfoot?

If that is you, please hear this early: in most cases, clubfoot is not caused by something a parent did or did not do in pregnancy. Most families do not get a single clear reason, and that uncertainty is hard. But uncertainty is not blame.

Clubfoot (also called congenital talipes equinovarus) happens before birth as the foot and lower leg develop. In many babies, experts believe there is a mix of inherited tendency and early developmental factors. That is why you will often hear clinicians describe clubfoot genetics and environmental factors explained as a “multifactorial” picture rather than one simple cause.

If you are new to the basics, this parent-friendly overview helps: what talipes is in the UK.

What clubfoot is, and what it is not

True clubfoot versus positional foot shape

One reason the causes conversation gets confusing is that not every turned-in foot on scan is true clubfoot. Some babies have positional talipes, where the foot is flexible and affected by position in the womb. True clubfoot is more rigid and has a specific pattern involving the ankle and tendons.

This distinction matters because families often ask, “is clubfoot caused by how baby lies in womb?” Position can influence how a foot looks, especially on scans, but true structural clubfoot is usually more than simple positioning.

You can read about that difference here: positional talipes vs clubfoot.

Why diagnosis can change from scan to birth

Prenatal talipes diagnosis is useful, but not perfect. Some babies flagged at 20 weeks are born with flexible positional feet, while others have clear clubfoot confirmed after birth. Ultrasound gives a strong clue, not always the final answer.

This is why your fetal medicine team may suggest repeat scans and careful review of the rest of baby’s anatomy, rather than making absolute promises from one image.

Evidence-based causes: what we know so far

Parents want clear cause-and-effect. Medicine often has to say, “we know some risk patterns, but we cannot always identify one direct trigger in one pregnancy.” That can feel unsatisfying, but it is honest and important.

1) Genetic contribution (common question: is clubfoot genetic?)

Many parents ask is clubfoot genetic. The short answer: genetics can play a role, but it is not always straightforward inheritance.

Clubfoot can run in families, but many babies with clubfoot have no known family history.
Having one affected relative can increase background likelihood, but it does not guarantee another child will have it.
Researchers think several genes may influence limb and connective tissue development, rather than one single “clubfoot gene” in most isolated cases.

In practical terms, genetic influence is one piece of the picture, not a verdict about anything you did in pregnancy.

2) Early developmental factors in the womb

Some clubfoot in pregnancy causes relate to how tissues and joints form in early development. Tendons, muscles, ligaments, and bone alignment may develop in a way that pulls the foot inward and downward.

This process happens very early, often before many parents know they are pregnant. That timing is one reason self-blame is usually misplaced.

3) Uterine environment and position: a limited but relevant factor

Parents ask, can anything in pregnancy cause clubfoot, including how baby lies. Position can affect limb posture, and reduced uterine space may contribute to positional foot deformities. However, for true rigid clubfoot, position alone is usually not enough to explain the full condition.

So for the question is clubfoot caused by how baby lies in womb: sometimes position affects appearance, but true clubfoot generally involves deeper structural development.

4) Association with other conditions in a minority of cases

Most clubfoot is isolated, meaning it appears on its own. In some babies, clubfoot occurs alongside neurological, muscular, spinal, or chromosomal conditions. That is why fetal medicine teams look carefully at the whole baby on scan and may discuss further tests if other concerns are seen.

This is not to frighten you. It is part of thorough care and planning.

5) Known risk patterns without simple blame

When discussing clubfoot risk factors pregnancy, clinicians may mention patterns seen in studies. These are risk associations, not proof of direct causation in your individual pregnancy. A risk factor is not the same as a reason to blame yourself.

If your team mentions risk factors, ask them to separate:

Population-level association (what is seen across many pregnancies)
What is actually known about your baby specifically
Whether this changes management, treatment, or outcome

Can anything in pregnancy cause clubfoot? A realistic answer

The honest answer is nuanced. Parents often want a yes/no list. A safer evidence-based approach is:

Most isolated clubfoot cases are not traced to one parental action.
There may be interactions between genetic susceptibility and intrauterine development.
Some reported risk associations exist, but they do not mean you “caused” your baby’s clubfoot.

If you are carrying guilt after online searching, it may help to reframe the question from “What did I do wrong?” to “What information helps my baby now?” That shift can reduce panic and improve decision-making.

A grounding statement you can repeat

“I did not choose this, and blame will not help my baby. I can focus on evidence, treatment, and support.”

Prenatal talipes diagnosis: what happens next in the NHS

In the UK, many parents first hear about possible talipes at the routine anomaly scan (typically around 18 to 21 weeks). After that, the NHS pathway usually aims to confirm findings, look for associated concerns, and prepare treatment planning early.

Typical NHS pathway after suspected clubfoot

Referral to fetal medicine for detailed ultrasound.
Review for isolated versus non-isolated findings.
Discussion of whether further testing is recommended based on scan features.
Planning where baby should be reviewed after birth.
Early referral to paediatric orthopaedics/clubfoot clinic so treatment can start promptly after delivery.

This overview is helpful for treatment planning in the UK context: clubfoot NHS treatment UK.

What to ask at fetal medicine appointments

Parents often freeze in clinic and forget their questions. Bring a written list. Here are practical questions to ask fetal medicine about clubfoot:

Is this likely isolated clubfoot or are there other findings?
How confident is the scan diagnosis at this stage?
Could this be positional talipes rather than structural clubfoot?
Do you recommend any additional tests, and why?
Which hospital team will manage us after birth?
How soon after birth should baby be seen by the clubfoot team?
Who do we call if we have concerns before delivery?

Script you can use in clinic

“I am feeling overwhelmed and worried I caused this. Could you explain clearly what is known, what is uncertain, and what I should focus on next?”

Most clinicians respond well to this direct approach. It gives them permission to address both medical facts and emotional distress.

Did I cause my baby clubfoot? The emotional reality and how to cope

This question can become intrusive, especially at night. Many parents replay food choices, stress, exercise, medication timing, and even one difficult day in pregnancy. That mental loop is exhausting and usually unfair to yourself.

Why guilt is common after prenatal diagnosis

Parents feel responsible for protecting the pregnancy.
There is often uncertainty instead of a single cause.
Internet searching can mix reliable medicine with blame-heavy myths.
You may be grieving the loss of the “straightforward pregnancy” you expected.

How to cope emotionally after prenatal clubfoot diagnosis

If you are searching how to cope emotionally after prenatal clubfoot diagnosis, practical steps often help more than general reassurance.

Name the feeling precisely: guilt, fear, anger, or uncertainty.
Limit doom-scrolling to one short evidence-based research window each day.
Bring your partner or trusted person to appointments and assign them note-taking.
Ask for written plans from your NHS team so you are not relying on memory when stressed.
Focus on treatment timeline and support systems, not hypothetical blame scenarios.

A script for family or friends

“We have had a prenatal diagnosis of clubfoot/talipes. The team says treatment after birth is well established. We are focusing on practical next steps and not on blame.”

A script for your own inner critic

“I am a parent dealing with a diagnosis, not a parent on trial.”

Preparing for birth and early treatment

Most babies with isolated clubfoot do very well with structured treatment, especially when families get clear support early. Knowing the pathway can lower anxiety.

Early treatment basics

The standard first-line approach in the UK is usually the Ponseti method: gentle manipulation, serial casts, often a minor Achilles tendon procedure when needed, then boots-and-bar bracing to maintain correction.

Read these step-by-step guides: Ponseti method complete guide and boots and bar complete guide.

Practical newborn checklist

Confirm your first orthopaedic/clubfoot clinic appointment before discharge or soon after birth.
Keep all scan letters and referral details in one folder (digital or paper).
Take photos of feet before treatment only if you want a record; this is optional.
Prepare clothing that works over casts (looser legs, easy access).
Ask who to contact out of hours for cast concerns.

For the first weeks at home, this can help: newborn clubfoot guide.

Sleep and skin practicalities during bracing

Many families struggle most with sleep disruption and skin irritation once boots-and-bar begins. You are not failing if this stage feels hard. There are practical adjustments that can help, including routine changes, sock fit checks, and prompt review for rubbing.

Useful reading: boots and bar sleep guide and boots and bar skin troubleshooting.

When urgent care is needed

Most of the road ahead is planned outpatient care, but there are times to seek urgent advice.

During pregnancy

Contact your maternity triage or NHS urgent maternity line promptly if you have:

Reduced or changed fetal movements (follow your local maternity guidance).
Vaginal bleeding, fluid loss, severe abdominal pain, or contractions.
Severe headache, visual disturbance, sudden swelling, or other red-flag pregnancy symptoms.

These symptoms are not “because of clubfoot” specifically, but they still need urgent assessment in pregnancy.

After birth, during casting or bracing

Contact your clubfoot team same day, urgent care, or NHS 111 depending on severity if your baby has:

Toes that become very swollen, cold, blue, pale, or persistently dusky in cast.
Unusual persistent crying suggesting significant pain not settling with normal comfort measures.
Cast slipping, foul smell, wet/soft cast, or pressure sores.
Fever, unwell appearance, poor feeding, or concerning lethargy.

If your baby appears acutely unwell, seek emergency care immediately.

Making sense of outcomes without false promises

Parents deserve realistic hope. With early and consistent treatment, many children with isolated clubfoot grow up active and independent. Some will need additional procedures or follow-up over time. The key point is that there is a well-established pathway and long-term support if needed.

For perspective beyond infancy, you may find this useful: clubfoot in adults long-term and clubfoot pain management.

What improves outcomes most

Prompt referral and early start of appropriate treatment.
Good cast and brace follow-up attendance.
Rapid response when skin/circulation concerns appear.
Supportive communication between family and care team.

Parent appointment toolkit: checklists and scripts you can use today

Checklist: before your next fetal medicine visit

Write your top three fears and top three practical questions.
Bring someone with you, in person or on speakerphone.
Ask for plain-language explanation and written follow-up plan.
Clarify exactly who coordinates care between maternity and orthopaedics.
Ask what would change the plan between now and delivery.

Checklist: questions for neonatal/orthopaedic team

When should treatment begin after birth in our baby’s case?
How often are casting appointments and how long is each visit?
What signs of cast problems require same-day review?
How do we contact the team out of hours?
How is brace fit checked and adjusted as baby grows?

Script: if you feel dismissed

“I understand uncertainty is part of this, but I need a clear step-by-step plan and who to call for each stage.”

Script: if guilt is overwhelming

“I keep thinking I caused this. Could you explain the likely causes again and why parents are usually not to blame?”

Common myths that increase unnecessary guilt

Myth: “If I had eaten differently, this would not have happened.”

There is no simple food-based prevention rule for isolated clubfoot in an individual pregnancy. Balanced antenatal care matters for overall health, but self-blame over one meal, craving, or missed perfect routine is not evidence-based.

Myth: “One stressful week caused this.”

Stress is hard and deserves support, but parents often over-attribute congenital differences to emotional strain. Clubfoot development is not explained by one bad week.

Myth: “If baby’s position caused it, treatment won’t work.”

Even when positional factors contribute, management remains structured and effective in many cases. Diagnosis and treatment planning matter more than guessing one cause.

If you are thinking ahead about support and rights

Most families focus first on treatment. Later, you may need practical support for appointments, travel, work flexibility, or benefits depending on your child’s needs. Information can help you plan without panic.

Putting it all together

When people ask “what causes clubfoot during pregnancy,” the truest answer is often: a combination of developmental and sometimes genetic factors, with many unknowns in individual cases. That answer is medically honest, but emotionally hard.

If you are carrying guilt, try this practical sequence:

Get clear diagnosis information and ask direct questions.
Follow the NHS referral pathway and treatment timeline.
Use scripts and checklists so stress does not silence your voice in clinic.
Treat self-blame as a symptom of shock, not a medical fact.

You are not expected to be calm all the time. You are expected to show up, ask questions, and keep going. That is already good parenting.

Frequently Asked Questions

What causes clubfoot during pregnancy in most cases?

In most cases, there is no single identifiable trigger. Clinicians usually describe a multifactorial picture: early developmental differences, possible genetic contribution, and sometimes environmental influences in the womb. For many families, no exact individual cause is found.

Is clubfoot genetic?

It can be. Some families have a history of clubfoot, and genetics can increase susceptibility. But many babies with clubfoot have no known family history, so genetics is often part of the story rather than the whole explanation.

Can anything in pregnancy cause clubfoot?

There are risk associations reported in research, but most isolated cases cannot be pinned on one parental action. The safest interpretation is that risk factors may influence probability at population level; they do not prove that you personally caused your baby’s clubfoot.

Is clubfoot caused by how baby lies in the womb?

Baby position can affect foot posture and can contribute to positional talipes appearances. True rigid clubfoot is usually a structural developmental condition and not just a temporary position issue.

How accurate is prenatal talipes diagnosis on scan?

Prenatal scans are helpful but not perfect. Some suspected cases are confirmed after birth, and some turn out to be flexible positional feet. Repeat imaging and postnatal examination are important for accurate final diagnosis and treatment planning.

Did I cause my baby clubfoot?

In the vast majority of cases, parents did not deliberately or directly cause clubfoot. Feeling guilty is common after diagnosis, but guilt is not evidence. Ask your team to explain your baby’s specific findings and focus on treatment steps you can control now.

What questions should I ask fetal medicine about clubfoot?

Ask whether the finding looks isolated, how confident the diagnosis is, whether further tests are recommended, what follow-up scans are planned, which team takes over after birth, and who to contact urgently if concerns arise before delivery.

When should I seek urgent help?

During pregnancy, seek urgent maternity advice for reduced fetal movements, bleeding, fluid loss, severe pain, or other red-flag symptoms. After birth, urgent review is needed for cast circulation concerns (cold/blue/swollen toes), severe persistent distress, cast problems, skin breakdown, or if baby seems acutely unwell.
