Abstract
Objective: Treatment of bilateral DDH in an older child can be performed in single-sitting or two-sitting procedures. This study compared the clinical outcomes and complications of these two surgical approaches. Methods: This retrospective, single-center, cross-sectional study included patients with bilateral DDH (age 15 months to 8 years) who received treatment in single-sitting or as a staged procedure at our medical center between 2000 and 2018 and were followed up for at least two years. We compared the postoperative acetabular index, central edge angle, and complications such as avascular necrosis (AVN) of the femoral head, lateral subluxation, re-dislocation, and infection between the groups. Results: This study included 56 hips in 28 patients (7 males, 21 females; age 2.2±1.0 years), of which 19 were treated in one sitting, and nine underwent staged procedures. The patients showed no intraoperative or immediate postoperative complications. Three postoperative complications were reported: bilateral subluxation, infection, and single hip re-dislocation. Five patients underwent revision surgeries. Most hips (53/56; 95%) showed excellent clinical outcomes at the last follow-up visit. Severin classification categorized 44 hips as excellent (class I), nine as good (class II), two as subluxation (class IV), and one as re-dislocation (class VI). The two surgical approaches showed similar outcomes and complication rates.
Conclusions: This study compared bilateral DDH treatment in single-sitting vs. two-sitting surgical procedures, finding no difference. Our results suggest that either approach can be used. The advantages of either approach might lie in yet un-investigated aspects.
