From: Is the diagnostic validity of conventional radiography for Lisfranc injury acceptable?
A 42-year-old man had a traffic collision and hurt his right foot. Chiodo-Myerson’s classification: three-column injury; Displacement classification: displaced injury. Both two observers made the correct diagnosis for two times, and didn’t change the initial treatment option (surgery) after evaluating CT image. a-b The conventional radiographs showed obvious tarsometatarsal joint dislocation (red arrows). It was easily diagnosed. c-f CT unraveled more details: intra-articular fractures of the base of the second and third metatarsal bone as well as extensive dorsal-lateral dislocation of the tarsometatarsal joint. The red arrow indicates the fracture fragments
