Hip dislocation is highly prevalent in some areas of China, such as the southwestern part of Shandong Province. A recent survey in rural areas of Shandong found that the incidence can be more than 10 times the normal incidence. This is related to the local “little habit” – many children’s parents wrongly believe that to the newborn child to straighten and tighten the legs can prevent the child’s legs grow into “rotund legs”. In fact, all children are born with varying degrees of bowed legs, and most children will naturally straighten their legs by the time they are 1.5 years old. Children, especially girls, are born with loose ligaments in the hip joints due to the hormonal influence of their mothers, and if the legs are tied straight, the result can easily cause a major problem of hip dislocation! When winter arrives, parents are even more likely to give their children long periods of leg-binding. Here, I would like to remind all mothers and mothers-to-be as well as grandmothers and grandmothers that they should never give their children leg-binding!!! The correct way to swaddle is to keep your child’s hips naturally apart! The correct way to swaddle a child is to let the hip joints separate naturally! The following is a simple “hip dislocation prevention and control” Q&A “hip dislocation prevention and control” Q&A 1, what is hip dislocation? Hip dislocation, medically known as “congenital hip dislocation” in the past, is the most common pediatric hip disease, the incidence of girls is 6-8 times higher than that of boys. Nowadays, the term “developmental hip dysplasia” is more commonly used. Because “developmental hip dysplasia” includes complete dislocation of the hip, subluxation and acetabular dysplasia, the so-called “developmental” means that the disease is not always congenital, but can also occur after birth. 2.What are the dangers of hip dislocation? If the disease is not treated or improperly treated, it can cause limp and hip pain, and lifelong disability. 3.What are the risk factors for hip dislocation? Girls, first birth, low amniotic fluid, breech delivery, having the same patient in the family, having other congenital malformations. Improper swaddling methods, such as: binding the child’s lower limbs too tightly after birth can easily cause hip dislocation! 4, hip dislocation has those common manifestations? (1) Children who cannot walk: asymmetric thigh skin pattern, unequal length of both lower limbs, asymmetric toe position, etc. (2) Children who can walk: one side of the hip joint dislocation shows limp and unequal lower limbs; the body sways back and forth when walking bilaterally, showing a “duck stance” gait. 5.How to diagnose hip dislocation? (1) Examination by experienced doctors and nurses. (2) X-ray film: the diagnosis cannot be confirmed for small babies. (3) Ultrasound examination: It is a new non-invasive examination technique in China as it can be diagnosed for newborn children without radiation damage. 6.How to treat hip dislocation? Basic principles of treatment: (1) Within half a year: sling and brace. (2) Half to 1.5 years old: brace, plaster. (3) From 1.5 to 2 years old: conservative treatment or surgery. (4) Above 2 years old: surgical treatment. 7.How to prevent ischemic necrosis of the femoral head during the treatment of hip dislocation? No matter what treatment method is applied, it may cause complications of “femoral head necrosis”. Early and correct treatment can greatly reduce its occurrence. Drug treatment has no effect on pediatric ischemic necrosis of the femoral head. 8, hip dislocation is not terrible, prevention and early and correct diagnosis and treatment is the key: (1) change the bad swaddling way! No leg strapping will not produce “rotundity”, while leg strapping may cause hip dislocation. (2) Increase awareness of prevention for children with risk factors for hip dislocation! For example, early diagnosis and treatment can be achieved after 1, 3, 6 and 12 months of life by experienced pediatric orthopedic and ultrasound doctors. (3) The earlier the treatment, the less it costs and the better the results! For example, children who start treatment in the neonatal period can recover completely without sequelae. Conversely, the older the child is, the more difficult and costly the treatment will be, and the more complications there will be!
