Introduction; Developmental dysplasia of the hip is a common pediatric hip disorder. Surgical intervention, including pelvic osteotomies, is often necessary. This study aims to evaluate the short-term clinical and functional outcomes of Dega pelvic osteotomy and high trans-iliac incomplete bi-cortical osteotomy.
Patients and Methods; This prospective multicenter study included 41 patients (51 hips) aged 9 months to 3 years with Developmental dysplasia of the hip (Tönnis grade III and IV) from March 2022 to August 2024. Patients were divided into two groups: Group A (26 hips) treated with Dega pelvic osteotomy and Group B (25 hips) treated with high trans-iliac incomplete bi-cortical osteotomy with a minimum follow-up of 8 months.
Results; Both groups showed significant improvement in acetabular index at the final follow-up (p < 0.001). The postoperative acetabular index was significantly better in Group 2 at 6 months and the last follow-up (p < 0.001). Clinical evaluation showed no significant differences between the groups. Complication rates were similar, with Group 1 experiencing more complications (anterior inferior iliac spine fracture, avascular necrosis of femoral head, overcorrection, and subluxation).
Conclusion: high trans-iliac incomplete bi-cortical osteotomy is a sufficient treatment to improve clinical and radiographic results in Developmental dysplasia of the hip, with a lesser complication rate and better acetabular index improvement than Dega pelvic osteotomy.
