Orthopaedics · Paediatric: congenital vertical talus

Sample item

A newborn has a rigid rocker-bottom foot, and a lateral radiograph in maximum plantar flexion shows the talus still pointing vertically with the navicular dislocated dorsally on the talar neck. What is the diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Congenital vertical talus

Congenital vertical talus is a rigid flatfoot with irreducible dorsal dislocation of the navicular on the talus. It is associated with neuromuscular and chromosomal disorders and treated with serial casting and limited surgery. Calcaneovalgus is a flexible positional foot.

Option by option

  • A. Metatarsus adductus

    Metatarsus adductus involves only forefoot adduction.

  • B. Calcaneovalgus foot

    Calcaneovalgus is flexible and the talus reduces on plantar flexion.

  • C. Clubfoot

    Clubfoot has an equinovarus posture.

  • D. Congenital vertical talus (correct)

    Correct. A rigid rocker-bottom foot with a vertical talus is the diagnosis.
