19-year-old female with left foot pain for 5 weeks. Markers were placed along the dorsum of the foot.There is a intra-articular fracture through the plantar corner of the base of the second metatarsal with mild displacement. There is edema in the fracture fragment and the adjacent bone. There is also edema within the base of the fourth metatarsal with a thin linear band of low signal intensity representing a nonarticular transverse fracture of the metatarsal. There is further edema within the third metatarsal, but we see no discrete fracture line. There is minimal edema within the tuberosity of the fifth metatarsal, but we see no fracture. The middle and lateral cuneiform bones also show edema, but no evidence of fracture line.Although the Lisfranc ligament is not optimally visualized, a band of low signal intensity extends from the medial cuneiform to the base of the second metatarsal just distal to the fracture line. This is favored to represent the main portion of the Lisfranc ligament, which appears intact.The visualized tendons appear intact. The study was not protocoled for detailed evaluation of the ankle ligaments, but they also appear intact.
1. Fractures of the bases of the second and fourth metatarsals.2. There is also edema within the third metatarsal, middle cuneiform, lateral cuneiform, and tuberosity of the fifth metatarsal bones, but we see no discrete fracture lines in these bones.Findings were relayed to Dr. Sandoval at the time of dictation.
