Cross sections of right foot
Section through navicular, cuneiform and cuboid bones
The section passes through the posterior parts of the three cuneiform bones, the anterior part of the navicular and cuboid bones, and through the tuberosity of the fifth metatarsal. The tendon of insertion of the tibialis posterior has been split into several fascicles (18) passing to the cuneiforms and to the base of the first metatarsal. The peroneus longus tendon (8) lies more laterally than in the previous section and is in an osteofibrous tunnel bounded below by the anterior continuation of the long plantar ligament (not labeled).
