Transverse Tarsal Joint
The Transverse Tarsal Joint (pronounced: trans-verse tar-sal joint), also known as the Chopart's Joint, is a significant joint in the human foot. It is formed by the articulation between the Calcaneus and Cuboid bones of the foot and the Talus and Navicular bones.
Etymology
The term "Transverse Tarsal Joint" is derived from its anatomical position in the foot. The word "transverse" refers to its crosswise orientation, "tarsal" pertains to the region of the foot it is located in, and "joint" signifies the point where the bones connect. The alternate name, "Chopart's Joint", is named after French surgeon François Chopart who described it in the 18th century.
Function
The Transverse Tarsal Joint plays a crucial role in foot mobility and stability. It allows for movements such as inversion and eversion of the foot, contributing to the foot's adaptability to uneven surfaces.
