The dorsal midtarsal ligaments collectively reinforce the dorsal aspect of the Chopart joint (talonavicular and calcaneocuboid), providing the dorsal constraint against plantarflexion at the midtarsal level.
Resist excessive midtarsal plantarflexion, provide the dorsal joint capsular reinforcement, and are the ligaments disrupted in dorsal midtarsal dislocation.
Dorsal midtarsal joint dislocations are uncommon injuries from high-energy axial loading, producing significant midfoot deformity. Anatomic reduction and stabilisation restores the dorsal midtarsal ligament tension.
