What structures make up the medial column of the tarsometatarsal joints?

The medial column of the tarsometatarsal joints is primarily composed of the 1st metatarsal and the medial cuneiform. The medial column plays an essential role in foot stability and function, particularly in providing support during weight-bearing activities. The first metatarsal articulates with the medial cuneiform, allowing for a stable base for the first toe and contributing to the overall medial arch of the foot.

The 1st metatarsal's close association with the medial cuneiform enhances the transfer of forces from the medial side of the foot during movement, offering both stability and mobility. This relationship is crucial for effective push-off during walking and running. Understanding the structures that compose the medial column can help in diagnosing and treating conditions related to foot mechanics and ensure proper design and application of orthotic devices in clinical practice.
