Radiographic Evaluation of the Calcaneocuboid Joint: A Cadaver Study

Eighteen cadaver feet were used for radiographic evaluation of the calcaneocuboid joint. The articular surface of the cuboid on all specimens was painted with a ra-diopaque material. Fractures and 1-mm step-off of the fractures were simulated in six specimens. The articular surface line and joint space could be visualized maximally on an oblique radiograph without overlapping structures. The oblique view is good for assessing the extent of the minor fracture-displacement, which is normally obscured by overlapping projections in dorsoplan-tar and lateral radiographs. If there is any doubt on the routine radiographs or any injury involving the calcaneocuboid joint, an oblique view of the foot should be performed. The early diagnosis and treatment of calcaneocuboid joint injuries may minimize development of posttraumatic degenerative arthritis.
