A trigonometric calculation of projected femoral neck shaft or cetrum-collum-diaphysis angle (CCD angle) and anteversion angle (AT angle) were assessed in normal adult Nigerian hips using the standardised biplane radiography described by Müller and Rippstein. A mean CCD angle and AT angle of 121 degrees+/-6 (SD) and 28 degrees+/-5 (SD) respectively were obtained in the 116 Nigerian adult hips assessed. The values obtained were inconsistent with quoted reference ranges of 130 degrees+/-7 and 10 degrees+/-7 respectively. There was however no significant difference between the female and male CCD and AT angles.
