MEASUREMENT AND RELATIONSHIP OF THE INCLINATION ANGLE, ALSBERG ANGLE AND THE ANGLE BETWEEN THE ANATOMICAL AND MECHANICAL AXES OF THE FEMUR IN MALES

The present study was undertaken to determine whether there is a const ant difference between the angle of inclination and the Alsberg angle and to evaluate statistical. relationships between the inclination ang le, Alsberg angle and the angle between the anatomical and mechanical axes of the femur. Measurements were taken from 50 male femurs (25 rig ht and 25 left, aged 30-40 years) from the Anatomy Department, Cukurov a University: inclination angle was determined between the neck and th e shaft of the femur; Alsberg angle, between a line drawn through the base of the epiphyseal plate and shaft of the femur; and the angle bet ween the anatomical and mechanical axes. The results showed that, for the right and left femurs respectively, the average inclination angle was 123.72 degrees and 125.96 degrees; the angle between the anatomica l and mechanical axes was 6.24 degrees and 5.96 degrees; and the avera ge Alsberg angle was 39.92 degrees and 40.61 degrees. The difference b etween the angle of inclination and the Alsberg angle in this study wa s 83.80 degrees and 85.36 degrees for the right and left femurs respec tively. The correlation coefficient between the angle of inclination a nd Alsberg angle was 0.96 and 0.93 for the right and left femurs respe ctively, while those between the angle between the anatomical and mech anical axes and inclination angle were -0.89 and -0.91 for the right a nd left femurs respectively. Furthermore, the correlation coefficient between the angle between the anatomical and mechanical axes and Alsbe rg angle were -0.88 and -0.90 for the right and left femurs respective ly.
