Isolated plantar fracture-dislocation of the middle cuneiform.

A previously unreported case of plantar dislocation of the medial cuneiform is described. The significance of this injury does not lie in its rarity, but in the amount of force required to cause such an injury. This large force may cause bony disruption, along with significant soft-tissue injury, and even compartment syndrome. Analysis of the preoperative evaluation, including the importance of a computed axial tomographicscan, operative intervention, and postoperative care are discussed.
