Ankle and foot

Trochlea of the talus

Trochlea tali

How to find it
Bring the foot into plantar flexion: the anterolateral corner of the articular surface then emerges from under the mortise and can be felt as a broad domed surface just in front of the lateral malleolus.
What you use it for
Only accessible in plantar flexion. An osteochondral defect of the trochlea is a common reason an ankle stays painful after a sprain.
