Bilateral fractures of acetabulum in a young girl with osteogenesis imperfecta and epilepsy

We report a case of bilateral displaced acetabular fractures including both columns fractures with protrusio acetabuli in a female patient, aged 15 years, with osteogenesis imperfecta (OI) (Sillence Type I), epilepsy, blue sclera and bilateral ipoacusia. Since OI is a rare genetic disorder characterized by an increased propensity to osteopenia, intraoperative fracture risks and hemorrhagic diathesis, we opted for the open reduction and internal fixation of the acetabula in two surgical steps and using two different approaches. Although the clinical outcomes are not excellent in this report (HHS 45/100), the authors suggest that chances of a good outcome with reconstruction of the acetabulum must be balanced against the benefits of early or late total hip arthroplasty. The goal was to delay a joint replacement as long as possible due to the patient's young age. Level of evidence: V, case report.
