Collodiaphysial Angle in South-Southern Nigerians

Abstract

The collodiaphysial angle is the angle between the axes of the femoral neck and its shaft. This angle was investigated in South-Southern Nigerians using 177 unilateral anterior posterior radiographs of the hip in subjects aged between 18 and 70 years with the standard technique of the Singh and Singh (1975). The angle ranged from 100°-155° with a mean of 137.330 and standard deviation of 7.57’ for males; and 121°-149°, mean of 135.43” and standard deviation of 7.05° for females respectively with significant differences between males and females in both groups (p<0.05). This study documents for the first time the collodiaphysial angle of South-Southern Nigerians and further confirms that the angle is wider in males than females.
