Surgical management of an acetabular fracture in type- I osteogenesis imperfecta through a modified Stoppa approach - A case report and literature review

Abstract

Introduction: Osteogenesis imperfecta (OI) is a disease caused by a genetic defect in collagen formation, leading to defective bone structure with osteopenia and repeated fractures. Case presentation: A male patient, 17 years old, diagnosed with OI type I, presented after falling downstairs with a right acetabulum fracture classified as an anterior column with a posterior hemitransverse fracture. The patient was treated by ORIF through a modified Stoppa approach; the anterior column was fixed using 3.5 locked reconstruction plate, while the quadrilateral surface was reduced and held in place using a spring plate. The postoperative and follow-up were uneventful. The fracture showed full union at three months, and at one year follow up; the functional outcome was excellent according to Harris hip score. Conclusion: Managing acetabular fracture in OI patients is challenging, and proper approach and fixation tools should be selected for better outcomes.
