1. Our results indicate that original artery of the nutrient artery, supplying the superficial branch of the radial nerve, is ideal for a free vascularized nerve graft.

2. Results The sural nerve nutrient artery has 2 to 4 branches with constant three branches and the vessel network is formed in an anastomosis way.

3. The nutrient artery of tibia is the main source of blood supply in the bone marrow.

4. Methods: The origin of nutrient artery of the abducent nerve root, and neurovascular relationships were observed on 18 brain stems.

5. Results: Nutrient artery of the trigeminal nerve root mainly came from pontine branches of basilar artery and from branches of internal carotid.

6. Objective To study effects of ligature of nutrient artery on blood supply of femur in rabbits.

7. Objective: To elucidate the effect of damaging the nutrient artery on long bone blood supply.

8. The blood supply of the metatarsals is derived from the nutrient artery, the periosteal arteries, the epiphyseo-metaphyseal arteries and the pseudoepiphyseal arteries.

9. The epiphyseal-metaphyseal regions are copiously supplied by vessels entering from the periphery and by the nutrient artery.

10. Objective To elucidate the effect on blood supply of the tibia following injury of its nutrient artery.

11. It is a general practice of the orthopaedic surgeons to strip the periosteum, to ream the medullary cavity etc,(Sentencedict) which may easily cause injury of the nutrient artery of the long bones.

12. Methods:Radionuclide imaging was used to survey the change of the femoral or tibial blood supply after ligating nutrient artery in rabbits.

13. Results:(1) The position and external diameter of peroneal artery, its accompanying vein and the distribution of fibular nutrient artery were observed.

14. The periosteum near linea aspera should not be stripped during operation on super medial femur fracture to avoid damage on superior nutrient artery.
