A 3-month-old male infant born in rural Maharashtra presents with bilateral clubfeet diagnosed at birth. His parents are non-consanguineous and there is no family history of CTEV. Regarding the management principles and investigations in this case, all of the following are appropriate EXCEPT:

Explanation

## Management Strategy in Congenital Talipes Equinovarus ### Timeline and Principles of Treatment **Key Point:** CTEV management follows a **stepwise, conservative-first approach**. Surgery is NOT the first-line treatment and should not be performed urgently in the neonatal period. ### Standard Management Protocol 1. **Immediate Assessment (Birth to 2 weeks)** - Clinical examination and diagnosis - Radiographic imaging (AP, lateral, and sometimes axial views) - Exclusion of syndromic forms and associated anomalies 2. **Conservative Treatment (First-line)** - **Ponseti casting method** — gold standard - Started within the first 2 weeks of life - Serial weekly manipulations and casts - Success rate: 90–95% with Ponseti method - Typically requires 5–8 casts over 8–12 weeks 3. **Surgical Intervention (Only if conservative fails)** - Indicated only after failed conservative treatment - **NOT** in the acute neonatal period - Typically considered at 6–12 months if Ponseti fails - Procedures: posteromedial release, soft-tissue releases, or osteotomies ### Why Option 3 is Incorrect **High-Yield:** Option 3 states "urgent surgical correction within the first 4 weeks of life if casting fails" — this is **WRONG** for multiple reasons: | Aspect | Correct Practice | Why Option 3 is Wrong | |--------|------------------|----------------------| | **Timing** | Surgery at 6–12 months minimum | 4 weeks is too early; Ponseti needs 8–12 weeks | | **Indication** | After failed conservative treatment (months) | Casting has not had adequate time to work | | **Risk** | Soft tissues are more mature at 6+ months | Operating at 4 weeks risks poor wound healing, stiffness | | **Success** | Ponseti succeeds in 90–95% | Premature surgery denies the child the best non-operative option | **Clinical Pearl:** The Ponseti method is so effective that it has revolutionized CTEV management globally. Surgeons now operate only on the 5–10% of cases that fail conservative treatment, not as first-line therapy. **Warning:** A common exam trap is confusing "early intervention" (which means starting Ponseti early) with "early surgery" (which is contraindicated). Early casting ≠ early surgery. ### Appropriate Investigations and Counselling **Mnemonic:** **RAG** = Radiographs (confirm diagnosis, assess severity), Assessment (clinical, exclude syndromes), Genetic counselling (syndromic forms, recurrence risk). - **Radiographs:** Essential before treatment to document baseline severity and rule out associated anomalies - **Genetic counselling:** Important for parental counselling, recurrence risk (2–3% if one parent affected, 1–2% if one sibling affected) - **Karyotyping:** Indicated if syndromic features present (e.g., Down syndrome, Marfan syndrome, arthrogryposis)
