Summary
This case report details the successful surgical fixation of pelvic fractures in an adult with Osteogenesis Imperfecta (OI). Standard fixation techniques can be effective for mild OI phenotypes with careful preoperative planning.
Area of Science:
- Orthopedic Surgery
- Genetics
- Biomedical Engineering
Background:
- Osteogenesis Imperfecta (OI) is a rare genetic disorder affecting type I collagen, leading to fragile bones and frequent fractures.
- Fracture management guidelines for adult OI patients are less established compared to pediatric cases.
- Adult OI patients present unique challenges due to altered bone biomechanics and potential hemostatic issues.
