Lisfranc ligament tear: Dorsal band disruption despite intact interosseous ligament

Short-axis MRI reveals a complete tear of the dorsal Lisfranc ligament while the interosseous band is only attenuated — always evaluate all three bands to avoid underestimating injury.

• Lisfranc ligament complex includes dorsal, interosseous, and plantar bands; injury may be isolated to one band.
• In this case, the dorsal component is completely torn on short-axis images, while the interosseous ligament is only attenuated.
• Careful assessment of all three bands is essential to avoid missing clinically significant Lisfranc injuries.
