Nip the “first hip” in the bud

  Taiwan’s “General Hospital of Taipei” is the hospital with the largest number of beds and the strongest technical strength in Taiwan. It is equivalent to our mainland’s “Xiehe”. “Professor Chen Tianxiong, the chief of the orthopedic department of the General Hospital, is a close friend of mine. This time, he sent his student, Dr. Jesse Yang, to Beijing to be a visiting academic scholar in our 304 joint surgery department for one month. Dr. Yang marveled at the fact that we have so many patients with congenital hip dysplasia (including hip dislocation) on the mainland. He was also pleased that we are at the forefront of periacetabular osteotomy in Asia. Dr. Jesse Yang told me that in Taiwan, it is absolutely impossible to correct congenital hip dysplasia by periacetabular osteotomy until the patient is young or adult, because Taiwan has already nipped congenital hip dysplasia in the bud.  In contrast, the incidence rate on the mainland is relatively high. For example, in the 1960s, the incidence rate was 3.9 per 1,000, and in 2010, according to the Tianjin Orthopedic Hospital, the incidence rate was 2.66 per 1,000. Among every 4 patients with “prefrontal hip”, there are 3 girls and 1 boy. Zhang Hong, Department of Orthopedics, The First Affiliated Hospital of the Chinese People’s Liberation Army General Hospital I have been calling for the nip in the bud of hip prematurity through various academic conferences, media, blogs and WeChat platforms. I never thought that Taiwan would really do it. We should really look up to our Taiwanese counterparts. Dr. Jesse Yang describes it this way: The maternity checkup for pregnant women in Taiwan includes screening for preeclampsia from the third month of pregnancy, asking for family history, asking the parents, grandparents, and grandparents. If any traces of family history are found, the mother will be included in the high-risk category of “pre-eclampsia”. After the birth of a fetus in Taiwan, the first thing that is done is to wipe away any secretions that may affect breathing, followed by a thorough basic examination of the newborn. One of the most important tests is the “hip screening”. The first step is the “frog test”, in which the baby’s legs are curled into a “little frog” shape to see if the hip joint acetabulum can stretch freely; the second part is to check whether the hip muscle texture of the baby is symmetrical. If one side of the hip is dislocated, the texture of the hip muscle on that side will become shallow or the number of tracts will become less. The third part is to check the mobility of the limb joints. If there is excessive mobility of both hip joints, a positive frog test, asymmetry of the hip texture depth, and a decrease in the number of hip texture tracts, an ultrasound will be performed on the child after full term. If further definitive diagnosis is needed, an X-ray will be chosen with special care. In Taiwan, biological parents and other relatives are not allowed to accompany newborns for X-ray examinations because the risk assessment of X-ray exposure in Taiwan is very strict and cautious. In order to prevent the newborn from moving around, a small anesthetic is given to the newborn. This small anesthesia needs to be undertaken by a very experienced anesthesiologist. Doctors in Taiwan do not choose to give X-rays to newborns unless it is absolutely necessary. They usually choose ultrasound because it is not invasive and damaging. At full term, they can diagnose whether the baby’s “anterior hip” is fully or partially dislocated. If it is a total dislocation, a cast is applied, and if it is a subluxation, a brace is applied. After such strict screening and timely treatment of positive children after the first month of life, it is almost impossible for Taiwanese children to grow up to be “prevertebral” patients. I really envy our Taiwanese counterparts, who have nipped the “pre-hip” problem in the bud. I hope that we in mainland China will learn and relearn from Taiwan’s regulations on strict monitoring during pregnancy and strict screening of newborns after birth, and implement them again. We should start with the advocacy and implementation by every hospital director, obstetrician and gynecologist, midwife, and orthopedic surgeon. I would also like to reiterate my call to all expectant mothers and grandparents of our babies, and all “relatives”, to ask the doctors who delivered our babies after birth if they did the “little frog” test. Did they check the symmetry of the gluteal muscle texture? If not, then make sure to ask the community doctor to come and check it out after discharge.
