Résumé
The tarsometatarsal joint (Lisfranc joint) is a synovial articulation of plane variety that is made up of three compartments. It is located between the bases of the five metatarsals and the anterior tarsal bones (medial, intermediate, lateral cuneiforms and cuboid bones). A great stability is provided by the particular shape of the joint compared to a mortise created by the cuneiform bones and the base of the second metacarpal, sometimes referred to as the "keystone concept", as well as strong dorsal, plantar and interosseous ligaments, including mainly the first medial cuneometatarsal interosseous ligament (Lisfranc ligament). Traumatic lesions are the commonest disorders of this joint. Violent accidents including a mechanism of forced plantar flexion combined with rotation are the main causes of injury. Imaging of the tarsometatarsal joint includes conventional radiographs, computed tomography (CT) and magnetic resonance imaging (MR). Conventional radiographic projections remain the first-line imaging modality. However, owing to their often subtle radiographic presentation, Lisfranc lesions are frequently overlooked. Due to its excellent spatial resolution and three-dimensional imaging capabilities, CT is the procedure of choice for the evaluation of the injured foot. MR may be more accurate at detecting ligamentous and synovial disorders particularly owing to its high density resolution. To cite this journal: Med. Chir. Pied 27 (2011).
