Talus Bone Second

The second talus bone (talus secundus) is a small bone of the foot located between the navicular bone and the heel bone. It is one of the seven tarsal bones and plays an important role in transmitting body weight and moving the foot.

The second talus bone is wedge-shaped and consists of a body, head and neck. Its body articulates at the top with the navicular bone, forming the talonavicular joint, and at the bottom with the calcaneus, forming the subtalar joint. The head of the bone faces anteriorly and medially, the neck faces posteriorly and laterally.

The main functions of the second talus bone:

1. Transfer of body weight from the navicular to the heel bone during walking and running.

2. Participation in flexion and extension of the foot.

3. Supporting the arches of the feet.

4. Shock absorption when walking.

Thus, the second talus bone plays a key role in the biomechanics and mobility of the foot, ensuring its mobility and stability when moving and supporting it. Damage to this bone can lead to gait disturbances and foot pain.
