Answer :
The etiology for a Lisfranc injury is hyperdorsiflexion. Lisfranc injuries occur in the midfoot region, specifically involving the articulation between the tarsal and metatarsal bones.
When the foot is forced into a hyperdorsiflexed position, such as during a fall or a high-impact trauma, it can lead to a Lisfranc injury. This hyperdorsiflexion causes damage to the ligaments and bones in the midfoot area, resulting in instability and pain.
Other movements mentioned like eversion, hyperplantarflexion, and hyperextension are not typically associated with Lisfranc injuries. It's important to understand the mechanism of injury to accurately diagnose and treat Lisfranc injuries.
