Ninety-eight hips from 75 patients (four boys, 71 girls) were evaluated retrospectively. The mean age at treatment initiation was 3.2 +/- 1.3 months (1-6 months). As the dysplastic hip matured into a type I hip, we applied the weaning regimen for 1 month. Seventy-two patients (96%) were treated successfully in 4.2 +/- 1.1 months (2-8 months). All of the failures were type IV hips. We did not detect any acetabular or femoral head pathology in the later follow-up. Semirigid hip orthosis is safe and effective as the first-line treatment method for delayed DDH except in type IV hips in patients under 6 months of age.
