From: Is the diagnostic validity of conventional radiography for Lisfranc injury acceptable?
A 30-year-old female hurt her right foot after slipping. Chiodo-Myerson’s classification: three-column injury; Displacement classification: non-displaced injury. Observer A made the wrong diagnosis for two times, and changed the initial treatment option (conservative treatment to surgery) after evaluating CT image. Observer B made the correct diagnosis at the second time, and changed the initial treatment option (conservative treatment to surgery) after evaluating CT image. a-b The Lisfranc injury was easily missed on plain X-ray. c-e The plantar intra-articular fractures of the base of the first to fourth metatarsal bones are shown on computed tomography images. The red arrows indicate the fracture fragments
