Factors of the inner thigh: femoral anterior torsion
Factors of the inner thigh: about anterior femoral twist
We will explain and consider the "femoral anterior twist", which is considered a skeletal factor in children's inner thigh gait.
In general, it is said that humans have a 30-degree anterior femoral twist at birth.
And with increased bone growth and muscle activity, this angle is said to decrease to 15 degrees by the age of 6.

The above illustration shows the hip joint and right foot from directly above, and in normal cases, there is a forward twist of 15 degrees, but in excessive forward twist, this angle is more than 35 degrees. When there is this excessive forward twist, in order to obtain the joint compatibility of the hip joint, it is adjusted by internally rotating the hip joint and turning the ankle inward (inner thigh). From this point of view, I think that even if you walk a little inward in childhood (until about 6 years old), you don't have to worry too much. However, postures and body usage that promote this forward twist should be eliminated as much as possible. At that time, the bones have growth plates (cartilage). During puberty (12~18 years old), it transforms from a growth plate to an adult bone. I believe that we should be able to lead to normal growth by then.
Growth plate: The "growth plate" (also called the epiphyseal line) near the end of the bone contains cartilage cells, and as these increase, the bone lengthens and increases height. By the end of puberty, growth ends at this stage, since these chondrocytes are replaced by bone cells.
One way to use the body that promotes femoral anterior torsion is to pay attention to patients in "sitting on the side". Many parents think that their children are not doing it, but when they actually ask their children to sit on the floor, they often sit on their sides with their legs slightly out of their upright positions. Please observe your child carefully. (According to the questionnaire for children who walk on the inner thighs, about 90% of the children were or still do to sit on the flat side.)
In addition to these musculoskeletal tests, we perform functional nerve tests for children who walk with inner thighs. This test checks for brain imbalances. During the growth period, it is desirable for the left and right brains to develop evenly, but for example, stimulation to the brain may interfere with the normal development of biased functional nerves due to long game time or short time jumping outside. We believe that eliminating this difference between the left and right functional nerves is also important for improving inner thigh gait.
Recently, I have examined and evaluated many children and believe that inner thigh gait may not be a simple musculoskeletal problem, but may be caused by complex problems such as decreased and increased neurological function during growth.
■For children who walk with inner thighs, we examine, evaluate, and treat three possibilities.
(1) Problems with the musculoskeletal system (pelvis, hip joint, knee joint, ankle joint, etc.)
(2) Problems with the functional nervous system (e.g., left-right balance of the brain)
(3) Problems with the above (1) and (2)
