Navicular & Cuboid Fractures

Tarsal navicular: body, tuberosity, and stress fractures; critical for medial column length and talonavicular congruity. Cuboid: 'nutcracker' fracture from forefoot abduction; lateral column length is key. Imaging: weight-bearing AP/lat/oblique + CT; MRI for stress fractures. Indications for surgery: displacement >2 mm, articular incongruity, medial/lateral column shortening, and instability with Lisfranc involvement. Fixation: screws/mini-plates for navicular; bridging plate/ex-fix for cuboid roof with bone graft to restore length.
