If the doctor suspects a femoral retroversion, he will conduct a physical examination of the legs and hips in addition to a thorough medical, developmental and family history. Out-toeing or “duck walk” – walking with the foot pointed outward instead of straight ahead.Symptoms of femoral retroversion may include: However, in some cases, this may be difficult to identify, especially if femoral retroversion is combined with a separate rotation deformity such as tibial torsion. The first symptom of femoral retroversion is usually a visual recognition of the rotated femur. Femoral retroversion can also occur after a physical trauma such as a femur fracture. It also appears to be related to the position of the baby as it grows in the womb.įemoral retroversion often runs in families, which may indicate that some children have a higher risk of being born with this condition. Femoral retroversion is often a congenital condition, meaning it is present from birth and develops in the womb. The exact cause of femoral retroversion is unknown. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. Femoral retroversion is also often called hip retroversion.įemoral retroversion can occur in one or both legs. Because the lower part of the femur is connected to the knee, this also means that the knee is twisted outward relative to the hip. This means the hip is twisted backward (posteriorly) in relation to the knee. Torsional deformity can also occur after a fracture where the bone heals with deformity or malunion.įemoral retroversion is a condition in which the femoral neck is rotated backward in relation to the femoral shaft. However, in excessive cases, surgery may be needed to correct the rotation. In cases where the child does not grow out of femoral retroversion, the condition may be mild enough not to cause any significant health challenges. In many cases, the child may grow out of it. The condition is usually congenital, meaning children are born with it. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. This condition can affect patients of all ages and leads to abnormal stress in the low back, hip and knee and abnormal gait.įemoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. In anatomy, the word “version” refers to the angle or rotation of all or part of an organ, bone or other structure in the body, relative to other structures in the body. The hip joint is where the femoral head (the top of the femur) meets the pelvis.
