Figure 4c. Coronal sections through the ankle of the cadaver of a 67-year-old woman. (a) T1-weighted spin-echo MR image (600/20) shows the posterior talofibular ligament (arrowhead), which originates from the concave surface of the fossa of the lateral malleolus and extends to the insertion on the talus. The calcaneofibular ligament (arrow) appears as a thin band of homogeneous signal intensity, which extends from the apex of the lateral malleolus to the lateral aspect of the calcaneus. Pb = peroneus brevis tendon, Pl = peroneus longus tendon. (b) Photograph of corresponding macroscopic section shows the posterior talofibular ligament (arrowhead) and calcaneofibular ligament (arrow). The inhomogeneous signal intensity of the posterior talofibular ligament on the MR image (a) corresponds to multiple fascicles with areas of interspersed fatty tissue. (c) Corresponding MR image obtained 6 mm posterior to a shows the transverse ligament (arrowheads) and posterior tibiofibular ligament (arrow) of the distal tibiofibular syndesmosis. The transverse ligament appears as a thin band of homogeneous signal intensity below the posterior tibiofibular ligament that extends obliquely to the tibia.
