Abstract
This cadaveric study specifically investigates the variations on the insertion of the posterior tibialis tendon (PTT) in the foot, a topic which is not well defined in anatomy discussions. The PTT insertion sites from 11 fresh-frozen cadaver feet (10 subjects) were evaluated. There were three distinct bands of the PTT seen in all specimens with variations on the insertion to the spring ligament (4/11), fifth metatarsal base (7/11), flexor hallucis brevis (9/11), and peroneus longus (4/11). This study also found a distinct slip to the abductor hallucis in five of the specimens.
