MRI of trauma to the foot and ankle.

Traumatic injuries involving the foot and ankle are very common. With the advent of magnetic resonance imaging (MRI) and its unsurpassed ability for soft tissue characterization, its utility in the investigation of these patients with foot and ankle trauma has rapidly expanded over the last decade. MRI has the unique capability to evaluate osseous, ligamentous, tendinous, and muscular injuries about the foot and ankle, with a single imaging study. MRI also allows for characterization of injury based on known biomechanical patterns. Injuries to specific soft tissue structures such as the Lisfranc and Spring ligaments can be accurately assessed on MRI when the imager considers both direct and indirect or supportive findings, allowing appropriate therapeutic intervention and rehabilitation.
