ABSTRACT
Objective: The lengths of long bones of adult skeletons are commonly used to estimate stature. The regression equations for calculating stature were established from the relationship between the height and the length of long bones. Methods: We measured 275 adults, ranging in age from 25 to 97 years. The length of six long bones; humerus, radius, ulna, femur, tibia and fibula were measured out. For both femur and tibia, they were measured in 2 different methods; maximum length and anatomical length. Microsoft Excel 2003 and Minitab 14, a statistical computer software (α = 0.05) were used to calculate and establish the regression equations for stature estimation of three groups of the differently sexual identification; male, female and unknown sex. Results: The length of two long bones, especially femur (max) + tibia (max) provides the most accuracy of stature estimation in all three groups. For the one long bone length, femur is the most accurate in every group. Conclusion: The overall of the results show that the upper extremities present the accuracy of stature estimation more than the lower extremities (except femur) in the male group. On the other hand, femur, tibia and fibula of the female group provide more accurate stature estimation than the upper extremities.
ABSTRACT
Objectives: The aim of this study was to evaluate the distance of the separation point of sciatic nerve in popliteal fossa and its relation to the length of femur in Thai cadavers. Method: One hundred and six Thai cadavers which composed of 105 right legs and 106 left legs were examined in this study. After dissection of the popliteal fossa, the distance of the separation point of the sciatic nerve above the level of both femoral epicondyles was measured in 84 right legs and 89 left legs of 66 male and 40 female cadavers. In addition the length of femur, which was the distance from posterior edge of the greater trochanter to the most prominent point of lateral epicondyles, was recorded. Results: In the specimen of this study, the sciatic nerves separated at a mean distance of 8.72 + 4.35 cm and 7.32 + 3.03 cm above the level of both femoral epicondyles in male and female cadavers with the highly variation range from 2.1 to 30.7 cm. The mean distances of the right and left legs in male cadavers were 8.49 + 4.39 and 8.90 + 4.32 cm respectively, being longer than in female cadavers (7.32 + 3.67 and 7.28 + 2.30 cm respectively) There were no significant differences in both the distance of the separation point and the length of femur by sex or side. Conclusion: The distances of the separation point of the sciatic nerve above the level of both epicondyles in Thai cadavers were highly variable and not related with the length of the femur.
