Subchondral insufficiency fracture of the talar head?

A subchondral insufficiency fracture of the talar head is a small crack or break in the bone just below the cartilage that covers the surface of the joint. It is often caused by repetitive stress to the ankle joint, such as from running or jumping. Symptoms of a subchondral insufficiency fracture of the talar head may include pain, swelling, and stiffness in the ankle. Treatment typically involves rest, ice, and elevation of the foot, as well as pain relievers. In some cases, surgery may be necessary to repair the fracture.
