Patient's question:
Patient is female, 11 years old, previously walked without obvious limp, but it became noticeable last year.Doctor's answer:
Congenital hip dislocation is one of the more common diseases among pediatric limb deformities. With the deepening of research, it was renamed developmental dysplasia of the hip after the 1990s. Girls are more affected than boys, and the left side is more common than the right side. The occurrence of this disease is related to race, gender, and environment, as well as gestational position (e.g., breech position), genetic factors, hormone levels (e.g., estrogen causing muscle and ligament relaxation), and postnatal wrapping methods (e.g., swaddling).
