medium · MCQ · Q-B2BCD6

A newborn infant is evaluated for foot deformities. The right foot exhibits severe equinus at the ankle, varus of the hindfoot, adduction of the forefoot, and cavus of the midfoot. The medial crease is deep, and the heel feels empty on palpation. The clinician initiates the Ponseti method. Which of the following is the correct sequence of correction of deformities in this method?

  1. A.Cavus -> Varus -> Adduction -> Equinus
  2. B.Cavus -> Adduction -> Varus -> EquinusCorrect answer
  3. C.Equinus -> Varus -> Adduction -> Cavus
  4. D.Adduction -> Cavus -> Varus -> Equinus

Solution

In the Ponseti method for clubfoot (Congenital Talipes Equinovarus - CTEV), the deformities are corrected in a specific mnemonic-based sequence using the acronym CAVE: Cavus (corrected first by supinating the forefoot to align with the hindfoot), Adduction, Varus, and Equinus (corrected last, usually via percutaneous tendo-achilles tenotomy).
