Patient: walking for a long time with pain in both hips, walking with abduction, 89 years untreated Can I look like a normal person after surgery? Will there be any heredity in childbirth? Zhu Zhen’an, Department of Orthopedics, Shanghai Ninth People’s Hospital: According to the symptoms you described and the X-ray film provided, your diagnosis should be clear: congenital hip dislocation and secondary osteoarthritis. It is Crowe type IV hip dislocation, which is the most serious type of congenital hip dysplasia. After surgery, you can walk normally. Congenital hip dislocation has a certain degree of heredity, so if you have children, you should have them examined early, and the earlier the disease is treated, the better the results. If the pain and dysfunction are affecting your work and life, surgery is indicated. Crowe type IV hip dislocation is the most serious type of congenital hip dysplasia, which is characterized by complete dislocation of the femoral head, significant shortening of the lower limbs, severe dysplasia of the acetabulum and upper femoral segment, and even deformity, requiring total artificial hip replacement. The difficulty of surgery is very high. Our department has rich experience in the treatment of Crowe type IV congenital hip dislocation, and no nerve injury has occurred in any case, achieving good results.
