Know the Facts About Hip Dysplasia

What is Hip Dysplasia? Hip Dysplasia or Developmental Dysplasia of the Hip is a medical term for general instability, or looseness, of the hip joint that may lead to dislocation or arthritis.

What does it have to do with baby carriers? According to the International Hip Dysplasia Institute, a not-for-profit effort to improve the health and quality of life of those afflicted with hip dysplasia, the important thing for new parents to remember is to use a baby carrier that allows the hips to fall or spread naturally apart to the side, with thighs and hips supported and knees bent.

Think of your baby as a jockey or frog, and he will have free movement of the hips resulting in natural hip development. When your baby is properly carried, their legs will look like the letter “M” with the buttocks down and the knees up. This is most important during the first six months of life.

Why? Babies spend up to nine months in the womb in the fetal position in which both hips and knees are bent or flexed. After birth, it takes several months for the joints to stretch out naturally, and parents can support the process by selecting products that encourage healthy hip development.

What are the signs of Hip Dysplasia? What makes this even more challenging is the fact that hip dysplasia is rarely painful to babies and may not be detected until baby is walking, or later. Therefore it is important not to restrict nor stretch out your baby’s hips as that can deform the hip socket. Although the risk of hip dysplasia or dislocation is greatest in the first few months, if left untreated, the result may only appear in the form of painful arthritis in adulthood.
