Abstract

For the recovery of broken bone or the free vascularized bone graft, the vascular to pography of the nutrient artery is very important, To establish the metric data of the nutrient foramen its number, direction and site had been observed and the size and position were measured The results are as follows 1 In 53 % of the femurs the number of the nutrient foramen was two, and in 57.1 % of the paired materials The number m both side was not different The femoral nutrient foramen opened toward the superior direction m the most cases(97.3%) The foramens appeared most commonly(58.9%) on the medial lip of the linea aspera of the femur The positional index was variable between 28.6 to 70.0 and It was 46.4±10.7 m average Foramina appeared most commonly(41.9%) m the 30-40 index area of total length of the femur 2 The number of the Tibial nutrient foramen was one in 91.0% of the cases All of the foramen opended toward the inferior direction The foramen was most commonly observed on the lateral to vertical ridge of the tibia(74.3%) Dividing the fibular into 10 parts, the positional index of the tibia was variable between 14.5 and 55.4 and It was 33.4±4.7in an average In 85.3% of the cases, the foramen observed in 4th segment 3 The number of the fibular nutrient foramen was one m the most cases(81.0%) The direction of the foramen was infenor in 88.0% of the cases The foramen positioned on the posterior surface of the fibular and Its average positional index was 47.9±11.3 and Its range was 20.3 to 72.4 The foramen was observed in 5th segment in the most cases(35.9%) 4 The Size of the nutrient foramen was measured by the various sized stylet The diameter of the femoral nutrient foramen was ranged from 0.5mm below 1.0mm In 46.6 % of the cases The that of the tibia was ranged from 1.0mm below 1.5mm In 53.2 % of the cases And that of the fibular was ranged from 05mm below 1.0mm In 54.0% of the cases
