The lateral malleolus extends slightly further distally than the medial and is gently convex transversely distally.
The lateral malleolus extends further distally than the medial and is distally convex.
The medial malleolus is flattened distally.
The postero-lateral border is prominent; it begins above at the apex, and ends below in the posterior border of the lateral malleolus.
It is continuous with that on the medial malleolus.
The external malleolus is lower and further back than the internal one.
This action strains the sturdy medial (deltoid) ligament of the ankle, often tearing off the medial malleolus due to its strong attachment.
It is when you have subluxation/dislocation of the peroneal tendons about the lateral malleolus.
