Short axis (coronal) proton density spin echo MR image. (TR/TE = 1800/12 ms) at the level of the midfoot shows a smooth, horizontally oriented, well corticated cleavage of the medial cuneiforms noted in case #2. The posterior tibial tendon inserts on the medial aspect of the plantar segment (arrow) and the dorsal and plantar bundles of the Lisfranc ligament each insert on the respective portions of the medial cuneiform (both arrowheads). Mid C = middle cuneiform; Lat C = lateral cuneiform.
