6 compared with 12 weeks treatment in the von Rosen splint is sufficient for Barlow and Ortolani positive hips: a comparative study of 237 neonates.

Background And Purpose: At our institution, newborns with Barlow or Ortolani positive hips have been treated for 12 weeks with the von Rosen abduction splint until 2012 when the treatment length was halved. We investigate whether acetabular development at 12 months of age and complications differ between hips treated with the von Rosen splint for 6 compared with 12 weeks.

Patients And Methods: 99 patients were included in the 6-week program and 138 patients in the 12-week program.

The International Hip Dysplasia Institute (IHDI) classification is more informative than the Tönnis classification.

Background: A new, supposedly more reproducible radiographic classification, set to replace the Tönnis classification of hip dislocations, was proposed in 2015: the International Hip Dysplasia Institute (IHDI) classification.

Purpose: To compare the IHDI classification with the Tönnis classification when evaluating the severity of hip dislocations as well as their respective inter- and intra-observer reliability.

Material And Methods: Since January 2000, Swedish-born children with a hip dislocation were prospectively registered.
