Development Of Torsional And Angular Alignment Analysis Of Deformity Of The Femur And Tibia
SOA Textbook Chapter in preparation
Torsion of the femur and tibia, as well as genu varum and genu valgum, are considered physiological variations of development that occur in normal infants and children. Infants commonly present with anteversion of the femur, medial tibial torsion and genu varum. With growth, the femoral anteversion decreases and the tibia rotates laterally. The genu varum gradually resolves and genu valgum develops. Abnormality of growth or disease can result in malalignment. Adequate management is based on an understanding of the cause and the natural history of the malalignment and the effectiveness of various treatments.

Femoral Anteversion
femoral version is defined as the angular difference between axis of femoral neck and the
transcondylar axis of the knee;
- excessive femoral anteversion (medial femoral torsion) is most common cause of in-toeing that first presents in early childhood;

Femoral anteversion in healthy children J Anat
Abstract Femoral anteversion (torsion) was measured in 219 healthy children aged 1-15 years (boys 128, girls 91). The hips and knees were examined using a standard static-image B-mode compound scanner. The torsion in each femur was calculated. The findings show: (1) A significant negative correlation between femoral anteversion and age (r = -0.43), with only 8-22% being accounted for by age (r2 value). (2) A significant correlation between anteversion of the two femora (r = 0.77). (3) No sex difference for femoral anteversion and its asymmetry. (4) Marked degrees of femoral anteversion asymmetry (more than 10 degrees) show a pattern suggesting a relation to age, side and possibly sex. (5) Abnormal femoral anteversion asymmetry in 12 children, there being an excess of children with orthopaedic symptoms and signs in the group with femoral anteversion outside 2 S.D. (6) A relation between anteversion asymmetry and foot length/tibial length ratio. (7) No relation of femoral anteversion to social class, order in family, parental age at birth of child, birth weight and presentation. (8) A significant correlation of femoral anteversion between siblings (r = 0.66).(Full text available)
