Nutcracker fracture of the cuboid

A nutcracker fracture of the cuboid refers to a cuboid bone fracture with associated navicular avulsion fracture due to compression between the bases of 4th and 5th metatarsals and calcaneus bone. The injury usually occurs secondary to traumatic abduction of the forefoot. This results in loss of the normal lateral column support and excess valgus force upon the medial column that commonly causes rupture of tibialis posterior tendon or avulsion fracture of its attachment onto medial aspect of the tarsal navicular bone.
