|Bone: Lateral malleolus|
|Lateral aspect of right leg. (Lateral malleolus labeled at lower left.)|
|Coronal section through right talocrural and talocalcaneal joints. (Lateral malleolus labeled at center right.)|
|Gray's||subject #62 260|
The lateral surface is convex, subcutaneous, and continuous with the triangular, subcutaneous surface on the lateral side of the body.
The medial surface presents in front a smooth triangular surface, convex from above downward, which articulates with a corresponding surface on the lateral side of the talus. Behind and beneath the articular surface is a rough depression, which gives attachment to the posterior talofibular ligament.
The anterior border is thick and rough, and marked below by a depression for the attachment of the anterior talofibular ligament.
The summit is rounded, and gives attachment to the calcaneofibular ligament.
Often when a patient fractures their ankle, this is the bone that suffers a chip or other significant damage.
