The collodiaphyseal angle of the femur in adult Nigerians.
An investigation was conducted on 256 people, consisting of 138 men and 118 women in Ile-Ife, Oyo State, Nigeria, to determine the variation of collodiaphyseal angle (CDA) of the femur with the transverse and vertical diameters of the head of the femur, with the neck, upper shaft diameter and lower shaft diameter of the femur. The effects of sex and geographical location on CDA were also considered. It was observed that the mean CDA of the mean was greater than that of the women. The mean CDA of the right femur is generally greater than of the left femur in each sex. CDA significantly correlates negatively with the diameters of the head of the femur and with the diameters of the shaft, but positively with the neck. CDA exhibited regional variation in the female Nigerian population. Mean CDA of females in Ile-Ife, South-West Nigeria seemed greater than that of females in Calabar, South-East Nigeria. But mean CDA in the males is not different. CDA in Nigerians seemed greater than the CDA reported for the other countries and races. This might be due to different cultural habits of physique exhibited by the different races.
