Dysfunction of the peroneus longus after fracture of the cuboid.

The author presents two case histories to demonstrate the disabling effects of fracture of the cuboid. He believes that a fracture of the cuboid is as disabling as an intra-articular fracture and should be treated in the same manner because an injury to any sinus or sulcus that contains a synovial lining for the free gliding action of a tendon should receive the same treatment as a joint injury.
