Abstract
In the treatment of femoral diaphyseal fractures in children the authors observed variable and sometimes fainly much expresed dorsal angulation of the shaft of the femur in sagittal plane. The authors decided to find out if it had been caused by physiologic conditivus or axial displacement of the fragments. One hundred and thirty one thigh bones, where the age and sex was known, were chosen from collection of the Department of Anatomy, First Faculty of Medicine, Charles University, Prague. Ventral and dorsal cortex angulation of the shaft of the femoral were measured. The results are:
1. The angulation of the thigh bones decreases with increasing age of both sex.
2. The angulation of the thigh bones decreases with increasing length of femur in both sex.
3. The angulation of the thigh bones of adult women is generally bigger than of the adult man (4 %).
4. Ventral and dorsal angulation of the femur correspond with the angulation of medullar cavity axis.
