The authors studied the descriptive and functional anatomy of the ligaments of the tarsometatarsal joint in order to identify the correlations between the means of stability of the joint and traumatic dislocations, their pathogenesis and treatment.
The stability of the tarsometatarsal joint is afforded not only by the ligaments classically ascribed to this joint but also by the prolongations of the lig. calcaneocuboideum plantare, the tendon of the m. tibialis posterior, the lig. cuneonavicularia plantaria and the tendon of the m. tibialis anterior. Experiments based on dividing the different ligaments and tendons led to propose a classification of the dislocations of the joint, i.e. dislocations by pronation, supination and plantar hyperflexion.
