What is Increased Femoral Anteversion?
Increased femoral anteversion is hard to describe using words. When the shapes of someone’s femur bones include femoral necks that point more forward compared to the femur shafts than most people’s,that person has increased femoral anteversion.
This shape causes intoeing (sometimes called pigeon-toed) and knock knees. This can be seen in a childas early as when the child begins to walk and sometimes becomes more obvious as they grow. Thesechildren oftensit in a “W” position and may trip and fall while running. Another symptom parents report is running with their legs swinging out to the side.
A physical examination is the best way to diagnose increased femoral anteversion. X-rays or other imaging studies are not usually necessary for us to figure out when the shape of the femur is the reason a patient intoes.
For most patients with increased femoral anteversion, no treatment is required as children with a small amount of intoeing are safe to run and play. There are no braces or special shoes to change the way their legs are shapedas femurs are literally rocks,and braces and special shoes cannot change their shape. Very fewkids with this characteristic require treatment. Surgery is not considered until the child reaches at least 7 years old.If a child reaches the age of seven and is tripping over her feet because she is intoeing, we consider doing surgery for her. Once again, surgery is indicated for only very few children who have increased femoral anteversion.
