The hip joint has a shape in which the hemispherical part (femoral head) on the femur side fits into the dent (recircular group) on the pelvis side. This innately unfit condition was commonly referred to as congenital hip dislocation, but in many cases it is rarely completely dislocated at the moment the baby is born, and the joints that are unstable at birth often gradually shift to dislocation, and recently the word "congenital" is not used, especially in Europe and the United States, and developmental Dysplasia of the It is called Hip (developmental hip dysplasia). This may cause the gradual dislocation. It may induce dislocation of the hip joint by accumulating a little childcare habit on the parent side, so be aware of the following three points! ■ 3 points 1 points that you want to be careful about how to raise diapers Let's make the diaper a crotch diaper with both legs bent into M-shaped and you can move your legs freely. Because it comes to tighten small things that do not fit the size, the legs will be difficult to move freely. Do not fix with both legs stretched out like "Okurumi". Also, do not pull up your baby's legs with your mother's one hand when changing diapers, put your mom's palms under the baby's buttocks and lift them. 2. Cuddle Let's do a "koala cuddle" for cuddles. When the baby is held from the front, it becomes an M-shaped open leg with both knees and hip joint bent. Make it customary to always put your mother's hand between the baby's legs, just as the koala is holding on to the tree. In the cuddle string, "cuddle string for frontal cuddle" becomes an M-shaped open leg, so there is no problem with use. If you use the "baby sling" for a side-hugging, stop it because you can not take the posture of the open leg and both legs are stretched. 3, Orientation Habit If there is a turning habit when sleeping, the opposite leg becomes a standing knee, and it may dislocate in an inner fallen posture. Lift the head and body on the direction side with a towel or mat, and devise so that the opposite leg falls outward and opens. *You can reduce the negative factors in your child's growth process just by changing the habit of childcare. Even if it is subluxation, for example, even if it is subluxation, the influence may become a factor of knee and hip joint disease in adulthood. Let's acquire important childcare habits in the growth process! *The X-ray image is a normal hip AP image of an 8-year-old child (Akamaru is a growth board) Source: ■Department of Orthopedic Surgery, University of Tokyo Hospital ■2016 Japan Medical Research and Development Agency Research Funded Comprehensive Research Project for Overcoming Child-Rearing Diseases Research on effective implementation of screening etc. based on disease epidemiology of infants Writers: Naoaki Kizu Language This page has been automatically translated.
