Lisfranc ligament

Lisfranc ligament is a significant anatomical structure in the foot, named after the French surgeon Jacques Lisfranc de St. Martin. It plays a crucial role in maintaining the stability and alignment of the tarsometatarsal joints.

Etymology

The Lisfranc ligament is named after Jacques Lisfranc de St. Martin, a French surgeon and gynecologist who served in Napoleon's army. He is known for his work on amputations at the level of the tarsometatarsal joints, which are now known as Lisfranc amputations.

Anatomy

The Lisfranc ligament is a strong band of fibrous tissue that connects the medial cuneiform to the second metatarsal on the plantar surface of the foot. It is part of the Lisfranc joint, which is composed of the five tarsometatarsal joints. The ligament is crucial in maintaining the alignment and stability of these joints.

Clinical significance

Injury to the Lisfranc ligament can lead to Lisfranc injury, which is often caused by direct or indirect forces to the foot. This can result in instability of the tarsometatarsal joints, leading to pain, swelling, and difficulty in walking. Diagnosis is typically made through physical examination and imaging studies such as X-ray, CT scan, or MRI. Treatment can range from non-surgical methods like immobilization and physical therapy, to surgical intervention in severe cases.
