Combined Midfoot Dislocation Involving the Naviculocuneiform and Calcaneocuboid Joints: A Case Report

Abstract

Background: Midfoot injuries such as dislocation of the naviculocuneiform and calcaneocuboid joints are very rare. They mostly result from high energy crushing trauma, which leads to dislocation of the midfoot in a plantar direction. Objective: To study the outcome of open reduction and internal fixation with K-wires in naviculocuneiform and calcaneocuboid joint dislocations. Patients and methods: Our case report of a 27 years old male who sustained an isolated left foot injury after a road traffic accident, radiographs showed a dislocation of the naviculocuneiform joint and fracture-dislocation of the calcaneocuboid joint. This uncommon injury pattern required open reduction and internal fixation with K-wires. Results: K-wires were removed after 12 weeks. At the 12 months follow up, he achieved a complete range of motion of the left foot and ankle with good functional outcomes and with no complications. The goal in such dislocations is to achieve a stable congruent joint with gradual rehabilitation to reach a good functional outcome. Conclusion: Closed dislocations involving the naviculocuneiform and calcaneocuboid joints are very rare, and they occur following a high energy trauma in the majority of cases. The goal of treatment in such injuries is to achieve a stable congruent joint with gradual rehabilitation to maximize the functional outcomes.
