Posterior tibial nerve injury

The tibial nerve descends vertically from the sciatic nerve, descends from the midline of the popliteal fossa to the lower edge of the diaphragm, enters the deep side of the soleus muscle, and becomes the posterior tibial nerve. The tibial nerve has motor branches to the gastrocnemius muscle, soleus muscle, diaphragm, diaphragm, posterior tibialis, longus flexor and longus flexor. It descends between the Achilles tendon and the medial malleolus, and is divided into the medial and lateral nerves of the plantar through the flexor support band, which controls the plantar muscles and the skin sensation of the plantar.
