Simultaneous versus staged surgeries for the treatment ofbilateral developmental hip dysplasia in walking age:A comparison of complications and outcomes

Abstract

Objectives: This study aims to compare the radiologicaloutcomes and rate of complication between single-stage andstaged operation for the treatment of bilateral developmentaldysplasia of the hip (DDH). Patients and methods: A total of 100 patients (13 males,87 females; mean age: 18.1±2.1 months; range, 12 to 36 months)with bilateral DDH who were older than 15 months of age andtreated with open reduction (OR) or Pemberton pericapsularosteotomy (PPO) were retrospectively analyzed. Of the patients,48 were operated with OR and 52 were operated with PPO.Improvements in acetabular indices, presence of avascularnecrosis, radiological results, and other complications were noted. Results: There was no statistically significant difference inthe preoperative acetabular indices, range of International HipDysplasia Institute (IHDI) classification, follow-up period, andage at the time of operation between the groups (p>0.05). Therewas no statistically significant difference in the acetabularindices, rate of avascular necrosis, and radiological results at theend of 24 months of follow-up between the groups (p>0.05). Conclusion: Our study results show no significant differencein the radiological outcomes and complications betweensimultaneous and staged surgeries for the treatment of bilateralDDH in children in the walking age.
