General anatomy of the plantar aponeurosis in baboons (Papio anubis) and humans. Both share a prominent central band and a lateral band that attaches proximally to the lateral tubercle of the calcaneus and distally to the joint capsule at the fifth tarsometatarsal joint. In baboons, the lateral band progresses further distal. The central band attaches proximally to the medial tubercle of the calcaneus and fans out distally to attach to the subcutaneous tissue and joint capsules of the first to the fifth metatarsophalangeal joints as well as the plantar bases of the corresponding proximal phalanges. The photos were provided with permission from Anthony Herrel (baboon) and Hanno Steinke (human).
