The asymmetry of the baby’s hip line is mainly caused by pediatric hip dislocation, which usually leads to asymmetry of the hip line, unequal length of the two lower limbs, limping and other symptoms, and the treatment methods are mainly divided into general treatment and surgical treatment and so on. 1. General treatment: general treatment is mainly suitable for children under 18 months old, the younger the age, the faster the development, within a certain period of time, the hip joint can be restored to the normal state. For children aged 0~6 months, the main treatment is Pavlik retractor treatment and over head traction reset method, etc. For children aged 6~18 months, manipulation reset under general anesthesia, plaster fixation can be used, and surgical incision reset can be considered if the child fails to manipulate the reset. 2. Surgical treatment: as the child grows older and the baby starts to walk, the degree of hip dislocation may be greater, and it is recommended to seek timely medical treatment for surgical treatment, such as incision and repositioning, femoral osteotomy, palliative surgery and so on. Therefore, if you find that your baby’s hip lines are asymmetrical, it is recommended that you go to the hospital as early as possible to find out the cause of the problem and treat it in time to avoid delays.
