Dorsal talonavicular ligament (highlighted in red)

The Dorsal Talonavicular Ligament is a ligament in the human foot that connects the talus and the navicular. It is one of the key components of the ankle and foot's complex structure, playing a crucial role in maintaining stability and facilitating movement.

Structure

The Dorsal Talonavicular Ligament is a thin, broad fibrous band that extends from the neck of the talus to the dorsal surface of the navicular bone. It is located on the top of the foot, hence the term "dorsal". This ligament is part of the tarsal complex, which is composed of seven bones that form the ankle and heel.

Function

The primary function of the Dorsal Talonavicular Ligament is to provide stability to the foot and ankle. It helps to prevent excessive movement between the talus and navicular bones, thus maintaining the alignment of the foot and ankle. Additionally, it plays a role in the foot's ability to bear weight and in the mechanics of walking and running.

Clinical Significance

Damage to the Dorsal Talonavicular Ligament can result in instability of the foot and ankle, leading to conditions such as flatfoot or pes planus. It can also be a source of foot pain, particularly in athletes and individuals who engage in high-impact activities. Treatment typically involves rest, physical therapy, and in severe cases, surgery.
