BACKGROUND: Injury to the tarsometatarsal joint is a relatively rare occurrence that is commonly missed, leading to debilitating outcomes. For this reason, it is considered a red flag in general practice. OBJECTIVE: This article reviews the current literature on tarsometatarsal injuries and describes clinical assessment, imaging and management. DISCUSSION: Lisfranc injuries refer to the displacement of the metatarsals from the tarsus, with special attention placed on the second tarsometa-tarsal joint and Lisfranc ligament. These injuries can occur in numerous circumstances, such as motor vehicle accidents, crush inju-ries and falls. Indirect mechanisms include axial force through the foot or twisting on a plantar flexed foot. Suggestive examination signs include plantar ecchymosis, mid-foot pain and positive findings in the provocative tests described in the article. Weight-bearing radiographs are vital for diagnosis. Correct and prompt management is key to avoiding posttraumatic arthritis, a devastating but common complication of Lisfranc injuries.
