29-year-old male with a history of remote trauma to the left foot presents with worsening left foot pain localized to the left fifth toe. Evaluate for Lisfranc injury. There is edema within the middle phalanx of the fifth toe surrounding a band of low signal intensity likely representing a nondisplaced fracture. Edema is also noted within the distal phalanx suggesting coalition of the middle and distal phalanges. The remaining phalanges are normal. The metatarsals and bones of the midfoot are unremarkable, although the proximal extents of the navicular and cuboid are not visualized in their entirety.The dorsal component of the Lisfranc ligament appears intact. Although the remaining components are not well visualized, there is no signal abnormality in the vicinity of the ligament or malalignment to suggest injury. The remainder of the soft tissues appear normal.
1. Fracture of the middle phalanx of the fifth toe.2. No findings to suggest Lisfranc ligament injury.
