What bones constitute the lateral tarsometatarsal joints?

The lateral tarsometatarsal joints consist of the fourth and fifth metatarsals, which articulate with the cuboid bone. This configuration is important for the proper biomechanical function of the lateral aspect of the foot, particularly in weight-bearing and propulsion during walking and running.

In the context of applied anatomy, these joints are critical for enabling the foot to adapt to varying terrains and to facilitate stability during movement. The articulation between the fourth and fifth metatarsals and the cuboid provides a necessary range of motion and flexibility, allowing for the necessary function of the lateral column of the foot.

Understanding this joint's anatomy is essential for professionals in orthotics and prosthetics, as pathologies affecting these joints can lead to conditions such as lateral foot pain or instability, which may require specific orthotic interventions.
