Peritalar dislocations are very rare injuries involving a simultaneous dislocation to both the subtalar and talonavicular joints. Mostly, they result from high-energy trauma such as road traffic accident and may also result from sports injuries. The most common type is medial dislocation. An inversion force in medial dislocation and an eversion force in lateral dislocation are applied to a plantar flexed foot. The treatment modalities for most peritalar dislocations include closed reduction and below-knee cast, although surgical intervention may be required in failed close reduction. We report a case of medial peritalar dislocation and comminuted fracture involving the posterior aspect of the talus with literature review on its biomechanics. A thorough knowledge of the biomechanics is essential for its better understanding and successful reduction maneuver.
