A 3 week old baby presents to clinic for DDH follow up. The baby was breech, and the initial exam showed some instability that the pediatrician was concerned about. The baby was referred, and the ultrasound showed an alpha angle of 58 degrees, and a beta angle of 70 degrees. What is your recommendation?

A 6 month old presents to clinic for DDH. Physical exam shows asymmetric skin folds and limited abduction. X-rays show a Shenton line that is disrupted, and an acetabular index of 38 degrees. What is your recommendation?
