Inner thigh walking 4th grade elementary school 8 years old boy (scaphoid / talus fall) Before the procedure: The video on the left is standing on one leg before the treatment. On the inside of the ankle, you can see that there is a movement of the scaphoid and talus to fall. This increased mobility in the ankle joint is also one of the factors of inner thigh gait. After the procedure, it is on the right side. Please see below for details. Click here for case cases in LanguageThis page has been automatically translated.

Factors of the inner thigh: About the anterior twist of the femur We will explain and discuss the "anterior twist of the femur", which is considered to be a skeletal factor of walking in the inner thigh in children. In general, it is said that humans have a 30-degree anterior femoral twist at birth. And it is said that due to bone growth and increased muscle activity, this angle decreases to 15 degrees by the age of six. （Acta Orthop Scand 54:18-23,1983In the above illustration, the hip joint and right foot are viewed from directly above, but in normal there is a 15-degree forward twist, but in an excessive forward twist, this angle is more than 35 degrees. When there is this excessive anterior twist, in childhood, the hip joint is adjusted by internally rotating the hip joint and turning the ankle inward (inner thigh) in order to obtain joint compatibility of the hip joint. For this reason, I think that there is no need to worry excessively even if there is a slight inner thigh gait in childhood (up to about 6 years old). However, postures and body movements that encourage this anterior twist should be eliminated as much as possible. At that time, the bones have growth plates (cartilage). At puberty (12~18 years old), it transforms from a growth plate to an adult bone. We believe that we should be able to lead to normal growth by then. Growth plates: The growth plates (also called epiphyseal lines) near the end of the bones contain chondrocytes, which increase in the length of the bones and increase their height. By the end of puberty, growth ends at this stage, as these chondrocytes are replaced by bone cells. One way to use the body to promote anterior femur twisting is to pay attention to "pechanko sitting". Many parents think that their children do not do it, but when they actually ask their children to sit on the floor, it is not uncommon for them to sit on their side with their feet flowing to the side. Take a closer look at your child. (According to the questionnaire of children with inner thigh walking, about 90% of the children used to sit or are still sitting) In addition to these musculoskeletal examinations, functional nerve tests are performed for children with inner thigh walking. This test checks for imbalances in the brain. During the growth period, it is desirable for the left and right brains to develop evenly, but for example, if the game time is long or the time to jump outside is short, the stimulation to the brain may be biased and hinder the normal development of functional nerves. We believe that it is also important to remove the left-right difference between this functional nerve and improve the inner thigh gait. 　Recently, I have examined and evaluated many children, and I think that inner thigh gait is not a simple musculoskeletal problem, but may be caused by a combination of complex problems such as decreased or increased nerve function during the growth process. ■ For children with inner thigh walking, we examine, evaluate, and treat three possibilities. (1) Problems with the musculoskeletal system (pelvis, hip joints, knee joints, ankle joints, etc.) (2) Problems with the functional nervous system (left and right balance of the brain, etc.) (3) Problems with the combination of (1) and (2) above Written by: Naoaki Kizu *Source: Kinesiology of the Musculoskeletal System (Medical, Dental and Pharmaceutical Publishing) Donald A.
