Six-month-old babies with asymmetrical leg lines do have the possibility of hip dysplasia, but it does not necessarily mean that they have this disease. If parents find that their baby has asymmetrical leg lines, they should go to a medical institution for further examination. Some hospitals that have ultrasound can use it to rule out hip dysplasia if there is no radioactivity. If this technology is not available, X-rays can also be used to rule out hip dysplasia. The majority of patients have a good prognosis after early diagnosis with the aid of braces, but only a few patients with hip dysplasia in adulthood need to be treated with osteotomy orthopaedic surgery.
