Title: An upgrade of the international hip dysplasia institute classification for the developmental dysplasia of the hip
Background and Objectives: The purpose of the current study was to upgrade the International Hip Dysplasia Institute (IHDI) classification for Developmental Dysplasia of the Hip (DDH).
Methods: The upgrading was suggested by adding the state of the acetabulum (Type A for the normal acetabulum and Type B for the dysplastic one). The pelvic radiographic films of 110 children suspected to have DDH were used by three observers to sort out the hips into grades according to the original form and the suggested upgraded one subsequently.
Results: The interobserver reliability between the observers improved from a good level (ICC 0.885, 95% CI 0.856-0.909) with the original form to an excellent one (ICC 0.919, 95% CI 0.898-0.936) when the upgraded form was used. When the upgraded form was used, only the hips of Grade 1 were distributed into Types A and B. While those hips assessed as Grade 2, 3, and 4 were all graded as Type B only.
Conclusion: The IHDI classification for DDH can be upgraded into Grade 1A, Grade 1B, Grade 2, Grade 3, and Grade 4.
