OBJECTIVE: To examine the long-term outcome of early abduction splinting versus active sonographic surveillance in newborns with mildly @entity572 . @entity1 AND METHODS: Between 1997 and 2003, 128 newborns with mildly @entity6349 and potentially unstable hips on ultrasound (43    <= a-angle < 50  ) were randomly assigned to immediate abduction treatment or sonographic surveillance. All were invited for a radiographic follow-up at 6 years. The radiographs were analyzed by a single radiologist masked to the randomization allocation, and markers of @entity572 (acetabular index, center-edge angle of Wiberg) and @entity2530 were reported. RESULTS: Eighty-three @entity1 (65%) agreed to participate in the follow-up (42 @entity1 from the treatment group). The mean acetabular index was 14.7   (SD: 5.6  ) for the treatment group and 13.9   (SD: 3.9  ) for the control group (mean difference: -0.8   [95% confidence interval: -2.9   to 1.3  ]). Values were within normal ranges for age for all @entity1 except for 1 female subject from the treatment group. The mean center edge was 26.6   for those treated and 26.4   for the active surveillance group (mean difference: -0.3   [95% confidence interval: -2.5   to 2.0  ]). None had markers suggestive of @entity2530 . CONCLUSIONS: We found no difference in radiographic outcome at 6 years of age between @entity1 allocated to initial splintage for 6 weeks and those offered active sonographic surveillance. The delayed acetabular ossification or persistent @entity1141 seen in a third of @entity1 from both groups at 1 year of age had completely resolved in all but 1 of the female subjects from the treatment group.
