| The medial and lateral malleoli of the tibia and fibula stabilize the talus. |
| Arterial ulcers tend to occur over the distal part of the leg, especially the lateral malleoli, dorsum of the feet, and the toes. |
| A second diagnostic point is the abnormal position of the calcaneus and scaphoid with relation to the malleoli and astragalus. |
| The talus is felt in front of the tibia, and the malleoli appear to be displaced backwards and to lie nearer the sole. |
| In all these injuries the body of the talus loses its normal relationship with the malleoli. |
| A metal hinge located at the lateral and medial malleoli permits both dorsiflexion and plantar flexion. |
