femoral anteversion
Forward angulation of the femoral neck relative to the plane of the femoral condyles.
Full Definition
Femoral anteversion describes the normal forward twist of the upper end of the femur, measured as the angle between the femoral neck and the plane of the knee joint. Excessive anteversion can lead to in-toeing gait patterns and hip instability, while decreased anteversion (retroversion) may contribute to out-toeing and impingement symptoms. Understanding this anatomical parameter is crucial for pediatric orthopedic assessment and surgical planning.
Usage
Usage note: Distinguish from acetabular anteversion, which refers to the socket rather than the femur.
