STABLE REDUCED HIP AFTER OPEN REDUCTION IN DEVELOPMENTAL DYSPLASIA OF THE HIP

Introduction: Developmental dysplasia of the hip (DDH) has a wide spectrum of conditions and treatment plans. Our aim in this study is to investigate related and controllable factors that can lead to secondary redislocation, and use them to foresee a concomitant pelvic osteotomy requirement. Methods: This is a retrospective case-control study on DDH cases reduced via an anterior approach without pelvic osteotomy in our orthopedics hospital from 2019 to 2021. After 24 months, we compared clinical and radiological findings between the failure and successful groups. Results: We reduced 49 hips (38 cases) using an anterior approach without osteotomy. The success rate was 89.8% (five cases re-dislocated), which is accountable for favorable odds. We found no statistically significant correlation between re-dislocation and bilaterality ([Formula: see text] = 0.64), gender ([Formula: see text] = 0.27) or age ([Formula: see text] = 0.82), or the AI before reduction ([Formula: see text] = 0.19). Conclusion: When the reduction has a wide safe zone in the operating room, the reduction of the hip without osteotomy can have satisfactory results, so based on the findings of our study, invasive procedures such as osteotomy will not be necessary if the hip is stable after the open reduction in the operating room.
