We performed a radiological measurement to know the defferencies of the growth of the acetabulum between Pavlik harness and Lorenz's method.α-angle, Sharp angle and the ratio between the depth and the length of the acetabulum were measured in serial X-ray pictures of 74 hips by Lorenz's method and of 45 hips by Pavlik harness.There was the continuous growth close to the control group in the Pavlik harness group but there was the deterioration of the growth from 5 to 7 years old in Lorenz group.The most characteristic change of the growth pattern occurred at 5 or 15 years old.The deterioration of the growth in Lorenz's group may be due to the damage of growth cartilage around the acetabulum during the period of treatment.
