How many joints comprise the transverse tarsal joint?

The transverse tarsal joint is comprised of two primary joints: the talonavicular joint and the calcaneocuboid joint. This anatomical region is crucial for foot function, as it allows for a significant range of motion and contributes to the function of the midfoot. The interaction between these two joints enables the foot to adapt to uneven surfaces and provides stability when walking or running. Understanding this joint helps in fitting therapeutic shoes, as it influences how footwear can accommodate various foot shapes and biomechanical needs.
