Navicular of foot blood supply

The navicular receives its blood supply from branches of the dorsalis pedis and tibialis posterior arteries. The convergence of these two networks creates a zone of poor blood supply (so-called "watershed" area) that predisposes the area to stress fractures and healing disturbances, possibly including non-union.
