Anastomosis around the Ankle Joint. The dissector 

 should next satisfy himself with regard to the anastomosis of 

 arteries which takes place around the ankle joint. On the 

 lateral aspect of the joint he will observe inosculations taking

 branch of the anterior tibial anastomoses with small twigs 

 from the medial calcanean branches of the posterior tibial.
