Pediatric hip dysplasia, if not diagnosed early, treated early, and handled appropriately, can lead to a series of hip disorders in the future. For example, mild hip dysplasia can evolve into hip subluxation, or from subluxation to hip dislocation, and finally lead to hip deformity. In other cases, minor hip dysplasia that is not detected early and treated appropriately can lead to a significantly shorter life span of the hip in the future. Many adult hip surgeons are now finding that a significant number of their hip replacement patients are the result of a legacy of hip dysplasia that was not detected in infancy or childhood.
