Anatomy · Lower limb: midtarsal joint

Sample item

A surgeon performs a midtarsal (Chopart) disarticulation of the foot. Which two joints form this line?

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

The answer and the reasoning

D. Talonavicular and calcaneocuboid

The transverse tarsal joint is formed by the talonavicular and calcaneocuboid joints and permits inversion and eversion. The tarsometatarsal line is Lisfranc's joint. The subtalar joint lies between talus and calcaneus.

Option by option

  • A. Naviculocuneiform and cuneocuboid

    The naviculocuneiform and cuneocuboid joints lie distal to the midtarsal line.

  • B. Subtalar and ankle

    The subtalar and ankle joints are proximal and are not the midtarsal line.

  • C. Tarsometatarsal joints only

    The tarsometatarsal joints form the Lisfranc line, which is more distal.

  • D. Talonavicular and calcaneocuboid (correct)

    Correct. The talonavicular and calcaneocuboid joints together form the midtarsal joint.
