Abstract

Introduction

Developmental dysplasia of the hip (DDH) includes femoral head subluxation or dislocation and/or acetabular dysplasia. The gold standard treatment for DDH during walking age remains controversial. Treatment modalities that have been proposed to treat DDH after walking age are femoral osteotomy and pelvic osteotomy. The aim of this study was to assess the radiographic results of surgical treatment of DDH after the walking age.

Case Presentation

Four patients were included in this study. All patients presented with DDH in walking age and underwent varus derotational osteotomy (VDRO). Measurements of acetabular index (AI) and migration percentage (MP) was done on pelvic x-ray before and after the procedure to assess the outcome.

Conclusion

This study showed satisfactory outcomes following femoral osteotomy in ambulatory DDH in terms of migration index and AI. Further study with more samples is needed for higher level of certainty.
