Midfoot structures are integral components of the longitudinal and transverse arches

Figure 70-1 A schematic representation of the midfoot demonstrating the mortise and tenon-like configuration of the second metatarsal base and the adjacent cuneiforms.

Figure 70-3 An anteroposterior radiograph of a lateral peritalar dislocation. The deformity is dramatic with the uncovered talar head noted medially in the subcutaneous tissues.

The posterior tibial tendon and a multitude of supporting ligaments including the spring, calcaneofibular, and/or deltoid may also be damaged. Articular injury is not infrequent.

The injury subtype is based on the forefoot's anatomic relationship to the talar head. Although four subtypes are possible, medial and lateral peritalar dislocations comprise the vast majority of injuries. The more common medial peritalar dislocation is thought to result from a forced inversion injury, while its counterpart results from a forced eversion injury.3

Most published series are relatively small with the mechanism of injury associated with high-energy trauma such as motor vehicle accidents, not athletic endeavors. Nonetheless, a perita-lar dislocation is not an uncommon athletic injury, especially with basketball players landing on an irregular surface.
