Coronal ultrasound images of the left hip (left) and right hip (right) were obtained after 5 weeks of therapy in a Pavlik harness with the patient located in the Pavlik harness during the exam. The coronal view is meant to simulate an anterior-posterior radiograph of the hip. The left hip is still dysplastic with there still being a shallow acetabulum and decreased alpha angle even though the left hip appears fairly well located in the left acetabulum. The left hip alpha angle measured 45 degrees (normal is usually greater than 60 degrees) but had increased since the last exam. The right hip was normal in appearance.
