The patient was diagnosed with bilateral hip dysplasia at 7 months old, with a right acetabular angle of 27 degrees and a left one of 29 degrees, and has been wearing a frog-like brace for 7 months. The recent pelvic X-ray examination was unable to determine the condition due to an incorrect shooting posture. It is recommended to take a new X-ray and pay attention to the shooting posture. The correct shooting posture should be: the child lying on their back, remove clothing and diapers, stay calm and relaxed, with both iliac anterior superior spines on the same horizontal line, legs naturally apart at shoulder width, and toes pointing inward, with the perineum covered.
