Talocalcaneal interosseous ligament

Looks like

A thick band inside the tunnel between talus and heel bone (tarsal sinus), linking the two bones.

What it does

The main bond of the subtalar joint, steadying the heel under the ankle.

Keeping it well

Injured in ankle sprains; sinus tarsi pain in front of the outer ankle may follow.
