Figure 5.

A higher degree of neonatal instability was associated with a smaller ossific nucleus at 12 months. Treatment differed between these groups (red dots).

Hips with a positive Ortolani test (i.e. dislocated in resting position) had smaller ossific nuclei than hips with a positive Barlow test (i.e. resting in the acetabulum but dislocatable) at 12 months. All these hips had 12 weeks of treatment (blue dots, subgroup analysis of dislocated hips). (n denotes the number of hips in each group. Error bars represent the 95% CI of the mean).
