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

Abstract

This study aims to compare the radiological outcomes and rate of complication between single-stage and staged operation for the treatment of bilateral developmental dysplasia of the hip (DDH).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 and treated with open reduction (OR) or Pemberton pericapsular osteotomy (PPO) were retrospectively analyzed. Of the patients, 48 were operated with OR and 52 were operated with PPO. Improvements in acetabular indices, presence of avascular necrosis, radiological results, and other complications were noted.There was no statistically significant difference in the preoperative acetabular indices, range of International Hip Dysplasia Institute (IHDI) classification, follow-up period, and age at the time of operation between the groups (p>0.05). There was no statistically significant difference in the acetabular indices, rate of avascular necrosis, and radiological results at the end of 24 months of follow-up between the groups (p>0.05).Our study results show no significant difference in the radiological outcomes and complications between simultaneous and staged surgeries for the treatment of bilateral DDH in children in the walking age.
