Correct Answer � D Explanation |
 |
The Lisfranc ligament is the ligament that connects the medial cuneiform bone to the base of the second metatarsal bone. This ligament plays a critical role in stabilizing the midfoot.
Lisfranc injuries occur when there is a disruption of this ligament, often seen in sports injuries or trauma to the midfoot.
This ligament bears the name of Jacques Lisfranc de St. Martin, a French surgeon who first described this anatomical structure. Importantly, injuries to the Lisfranc ligament can lead to instability and often require surgical repair.
Evaluation of Incorrect Options:
Spring ligament (also called the plantar calcaneonavicular ligament): It supports the medial longitudinal arch of the foot, preventing excessive flattening and helping in weight-bearing activities.
Deltoid ligament: This strong ligament on the medial side of the ankle stabilizes the ankle joint, especially against eversion (outward turning of the foot).
Chopart ligament: This ligament is part of the Chopart joint complex, which plays a key role in connecting the hindfoot to the midfoot and is crucial for foot movement, including inversion and eversion.
