Outcome of Closed Reduction of Developmental Dysplasia of Hip Before First Year of Age, A Retrospective Cohort Study, Saudi Arabia

Abstract

Background: Developmental dysplasia of hip (DDH) management is challenging hence there is no fixed rules or radiographic criteria to assess and manage DDH. There are many treating modalities including closed reduction, open reduction, skin traction, hip Spica and many others. This study is to assess the outcome of closed reduction in patients below 12 months of ages.Method: A retrospective study among patients with DDH who underwent closed reduction before the first year of age in a major referral medical center. The study included 100 patients and 168 hips. Average of follow up period was 5.97 years (±3.01). Couple of variables were measured in AP x ray of pelvis to assess the outcome of closed reduction. Results: Most of the hips were grade 1 and 2 according to the IHDI (International hip dysplasia institution) classification. Significant improvement in the acetabular index post closed reduction. In addition to the normalizing of CE angel's values. Also, majority of hips were severin's class 1 and 2 which were associated with good outcome.Conclusion: Safe closed reduction in patients with DDH below one year of age had a great outcome, less AVN, less growth complications and decrease the need of future open reduction.
