The canine fibula is a long, slender bone that articulates with the tibia and also serves as a site for muscle attachment. It arises from the distal aspect of the semimembranosus muscle belly and courses through the popliteal fossa between it and the semitendinosus muscle medially and the biceps femoris laterally. [Figure 9A, 9B] The normal calcaneonavicular component of the bifurcate ligament is almost always clearly seen; therefore, an absent or indistinct ligament should prompt a higher degree of suspicion for midtarsal sprain. From this insertion, it extends posteromedially to blend with the medial margin of the knee capsule and inferior surface of the medial tibial condyle.
