FUNCTIONAL AND RADIOLOGICAL OUTCOME OF TRIPLE PELVIC OSTEOTOMIES IN MANAGING ADOLESCENT HIP DYSPLASIA: A CASE SERIES

Introduction: Triple pelvic osteotomies can reduce hip subluxation, medialize the hip joint center, and redistribute the contact stresses over the whole articular surface and can be performed regardless of whether the triradiate cartilage is open or closed. Methods: In this case series, patients’ radiographs and data who underwent triple pelvic osteotomy were sought retrospectively, and those aged 8-18 years who had proven acetabular dysplasia and an adequate hip range of motion were included. Over the follow-up period, complications were recorded, as were radiographic outcomes. Results: Twenty-two patients with 29 hips were included. Patients were aging on average 14.5 ± 3 years, with 65.5% females and an average of 78 months (58–102) follow-up. Harris Hip Score (HHS) was used to evaluate hip function, which was excellent in 13 hips (44.8%), good in 15 (51.7%), and fair in 1 hip (3.5%). Complications were encountered in 6 cases, including an anterior column fracture, hip, lateral femoral cutaneous nerve, sciatic nerve injury, and superficial wound infection. Conclusion: Triple pelvic osteotomies in adolescents for correction of acetabular dysplasia show good functional and radiological short-term outcomes.
