Lisfranc Injury: Current Concepts.

Lisfranc injuries range from sprain to fracture-dislocation. Radiologists must have a thorough understanding of anatomy, mechanisms, and patterns of these injuries to diagnose and help clinicians assess treatment options and prognosis. The initial imaging evaluation of patients with a suspected Lisfranc injury consists of non-weight-bearing radiographs. In patients with high-energy injuries, the diagnosis is straightforward, and patients usually undergo CT for surgical planning. In patients with low-energy injuries, when findings on initial radiographs are equivocal, further evaluation is performed with weight-bearing radiographs, CT, or MR imaging. Stable injuries are treated conservatively, whereas all other injuries require surgical interventions.
