There are a number of studies in the world that uses tibia for sex determination, however there are no such studie in Korea. Eight variables were used to determinate sex of tibia. The sample consisted of 170 tibiae (from 55 males and 30 females). The ages for these specimens ranged from 18 and 91 years. Vernier caliper (Absolute Digimetric, Mitutoyo Corp, Japan), osteometric table (Osteometric table, GPM Corp, Swiss) and Ruler (Ruler, Peace Corp, Korea) were used to measure these variables and statistical analysis was performed. Result showed that the accuracy of maximum breadth of lateral articular surface of proximal condyle (LAB) was highest to reached 80.5%; on the contrary, circumference the body that the point found nutrient foramen (CNF) was lowest correlation variable to reach only 68.4%. Other variables except for CNF showed higher than 75.0% accuracy. Equation of sex determining function was made by the stepwise logistic regression using maximum breadth between lateral and medial condyle on the superior aspect (PAB) and maximum length of lateral articular surface of proximal condyle (LAL). The accuracy of the equation showed 84.8%. This study showed that certain parameters of the tibia useful for sex determination in the case of fragment of tibia are found.
