Lateral border of 1 st metatarsal is aligned with lateral border of 1 st medial cuneiform. Medial border of 2 nd metatarsal is aligned with medial border of 2 nd intermediate cuneiform. Medial and lateral borders of the 3 rd lateral cuneiform should align with medial and lateral borders of 3 rd metatarsal. Medial border of 4 th metatarsal aligned with medial border of cuboid.

To systematically review current diagnostic imaging options for assessment of the Lisfranc joint. PubMed and ScienceDirect were systematically searched. Thirty articles were subdivided by imaging modality: conventional radiography 17 articles , ultrasonography six articles , computed tomography CT four articles , and magnetic resonance imaging MRI 11 articles. Some articles discussed multiple modalities. The following data were extracted: imaging modality, measurement methods, participant number, sensitivity, specificity, and measurement technique accuracy. Conventional radiography commonly assesses Lisfranc injuries by evaluating the distance between either the first and second metatarsal base M1-M2 or the medial cuneiform and second metatarsal base C1-M2 and the congruence between each metatarsal base and its connecting tarsal bone. CT clarifies tarsometatarsal TMT joint alignment and occult fractures obscured on radiographs.
