Transverse tarsal joint

Transverse Tarsal Joint

The Transverse Tarsal Joint (also known as Chopart's Joint) is a significant joint in the human foot. It is composed of two individual joints: the talonavicular joint and the calcaneocuboid joint. These joints work together to allow for a wide range of movement in the foot, including inversion, eversion, plantar flexion, and dorsiflexion.

Anatomy

The Transverse Tarsal Joint is located in the midfoot region, between the tarsal bones and the metatarsal bones. The joint is named for its transverse orientation, which runs across the foot from the medial to the lateral side.

Talonavicular Joint

The talonavicular joint is a ball-and-socket joint formed by the articulation of the navicular bone and the head of the talus bone. This joint allows for a significant degree of movement in multiple directions.

Calcaneocuboid Joint

The calcaneocuboid joint is a gliding joint formed by the articulation of the calcaneus bone and the cuboid bone. This joint primarily allows for inversion and eversion movements of the foot.

Function

The Transverse Tarsal Joint plays a crucial role in the complex movements of the foot. It allows for the necessary flexibility and adaptability of the foot during walking and running on uneven surfaces. The joint also contributes to the foot's shock-absorbing capabilities.

Clinical Significance

Injuries or disorders affecting the Transverse Tarsal Joint can significantly impact mobility and quality of life. Conditions such as arthritis, sprains, and fractures can cause pain and limit movement in the joint. Treatment options can range from conservative measures like physical therapy and medication to surgical interventions in severe cases.
