What is the Difference Between Tarsal and Metatarsal?

The difference between tarsal and metatarsal bones lies in their location and function within the foot.

Tarsal bones are a group of seven bones that form the rear section of the foot, including the ankle and heel. They can be divided into three groups:

1. Proximal group: talus and calcaneus, which form the hindfoot and connect with the tibia and fibula bones of the lower leg.
2. Intermediate group: navicular bone, which plays a key role in maintaining the medial longitudinal arch of the foot.
3. Distal group: lateral cuboid and three cuneiforms, which articulate with the metatarsals and maintain the transverse arch of the foot.

Metatarsal bones are a group of five tubular bones located in the middle of the foot, between the tarsal bones and the phalanges. They are numbered I-V, moving medial to lateral (big toe to little toe). Each metatarsal consists of a head, shaft, and base, and articulates with the cuboid bones and proximal phalanges. The metatarsals play a crucial role in transmitting weight from the tibia to the foot and maintaining the arch of the foot.

In summary, tarsal bones form the rear section of the foot, including the ankle and heel, while metatarsal bones are located in the middle of the foot and connect the tarsal bones to the phalanges (toe bones).

Comparative Table: Tarsal vs Metatarsal

The main difference between tarsal and metatarsal bones lies in their structure and location in the foot. Here is a table comparing the two:

Tarsal bones are short bones located in the posterior aspect of the foot, forming the ankle and heel. They provide limited motion and support for the foot. On the other hand, metatarsal bones are long bones located in the anterior portion of the foot, forming the sole. They transfer body weight and provide leverage for movement.
