Tarsometatarsal ligaments

Tarsometatarsal ligaments are a group of ligaments located in the foot. They connect the tarsal bones to the metatarsal bones, providing stability and support to the foot structure. These ligaments play a crucial role in foot movement, particularly in walking and running.

Anatomy

The tarsometatarsal ligaments are divided into three groups: dorsal, plantar, and interosseous.

• The dorsal tarsometatarsal ligaments are located on the top surface of the foot. They connect the tarsal bones to the metatarsal bones.
• The plantar tarsometatarsal ligaments are located on the bottom surface of the foot. They are thicker and stronger than the dorsal ligaments, providing more support and stability.
• The interosseous tarsometatarsal ligaments are located between the bones. They are the strongest of the three groups and play a crucial role in maintaining the structural integrity of the foot.

Function

The primary function of the tarsometatarsal ligaments is to provide stability to the foot and facilitate movement. They allow the foot to flex and extend, enabling actions such as walking, running, and jumping. They also help to distribute weight evenly across the foot, preventing injury and maintaining balance.

Clinical significance

Injuries to the tarsometatarsal ligaments can occur due to trauma, overuse, or degenerative conditions. These injuries can result in pain, swelling, and difficulty in movement. Treatment may involve rest, physical therapy, or in severe cases, surgery.
