the arterial blood supply of the tibial and practical consequences in the periosteum of the human tibia the arterial blood supply shows a general sectorial angioarchitecture there are 4 segments proximal and distal 15 proximal and distal diaphysis the proximal 15 of the tibial periosteum is supplied with blood by the aa recurrentes tibiales anterior et posterior and the aa inferiores medialis et lateralis genus at the proximal diaphysis next 310 of the tibia periosteal branches arise from the a tibialis anterior and the a tibialis posterior the distal diaphysis following 310 below the middle of the tibia is nourished exclusively by semicircular rami periostales of the a tibialis anterior which move around the bone from both sides and join with each other at the facies medialis it is the only sector which is supplied by a single main artery concerning the periosteal blood supply of the distal 15 of the tibia 2 different types are found in 23 of the cases the lateral side is nourished by a great vessel of the a fibularis which is supported by branches arising from the a tibialis anterior in 13 of the cases this vessel of the a fibularis is absent and rami periostales of the a tibialis anterior nourish the lateral aspect of the distal tibia alone the dorsal region is supplied in all cases by rami of the a fibularis and a tibialis posterior on the medial side the periosteal nourishment is ensured only by anastomoses both the facies lateralis and the facies posterior are supplied by direct branches which arise from the main arteries of the lower legabstract truncated at 250 words
