Hip dysplasia usually cannot recover on its own, and needs standardized treatment to be cured, otherwise it will be complicated by arthritis and other complications, which will make surgery more difficult. Hip dysplasia is a common disease in pediatric orthopedics, the cause of which has not yet been clarified and is mostly believed to be related to genetic, mechanical and hormonal factors. Hip dysplasia cannot be cured on its own, and if no treatment is taken, the condition will only worsen. Therefore, once diagnosed, children with hip dysplasia from birth to 6 months old can be treated with Pavlik sling; children aged 7 to 18 months old can be fixed with plaster after closed reset; children aged 18 months to 8 years old need to be treated with surgical procedures, such as simple incision and reset. Hip dysplasia can only be cured through standardized treatment, and the prognosis is better if the disease is treated as early as possible. If the disease reaches an advanced stage, it may be complicated by arthritis and other diseases, and the difficulty of surgery will increase, and in serious cases, it may jeopardize health.
