description: "Femoral torsion, also known as femoral rotation or femoral version, refers to the twist between the proximal and distal parts of the femur on the transverse plane. Femoral anteversion averages between 30-40 degrees at birth, and between 8-14 degrees in adults. This term applies if the amount of femoral torsion deviates from this range."
