Ankle and foot

Neck of the talus

Collum tali

How to find it
Place your finger on the front of the ankle just distal to the joint line, where the bone clearly narrows between two wider parts. Move the foot in and out of inversion: that narrow stretch turns under your finger.
What you use it for
The neck is the weak point of the talus: it breaks here in a fall from height with forced dorsiflexion. The blood supply runs through it, so a fracture threatens the head.
