Reliability of 3 Radiologic Classifications for the Severity of the Developmental Dysplasia of the Hip in Children Older Than 4 Years
Conclusion:
The inter-rater and intrarater reliability of all 3 classifications (IHDI, Tonnis, and LMH) is excellent. All classifications can be used till the age of 8 years. The difficulty in selecting the superolateral margin of the acetabulum is a major cause of inter-rater variability.
Level of Study:
Level III.
