What structure forms the articulation between the tarsals and metatarsals?

The articulation between the tarsals and metatarsals is specifically referred to as the Lisfranc joint. This joint complex is situated in the midfoot area and plays a crucial role in the stability and mobility of the foot. The Lisfranc joint complex comprises a series of articulations between the bases of the metatarsal bones and the cuneiform bones, as well as the cuboid bone of the tarsals.

The importance of the Lisfranc joint extends beyond mere anatomical description; it is vital for proper locomotion and weight distribution during various activities such as walking and running. Injuries to the Lisfranc joint can significantly impact foot function and require proper assessment and treatment.

The other joints mentioned do not serve the function of connecting the tarsals to the metatarsals. The patellofemoral joint is involved with the knee, the talocrural joint relates to the ankle complex, and the acetabulofemoral joint pertains to the hip. Understanding the specific locations and functions of these joints helps clarify the role of the Lisfranc joint in the overall biomechanics of the foot.
