Nathalie was diagnosed with osteogenesis imperfecta (Type IV) as a toddler. Osteogenesis imperfecta is a congenital genetic condition that causes brittle bones which fracture easily from minor impact and in some cases for no reason. As a result, Nathalie experienced multiple fractures throughout her childhood which required several surgical procedures. Given the nature of osteogenesis imperfecta, these childhood fractures were to be expected. However, Nathalie’s parents’ diligence in immediately seeking care has helped to limit the long-term effects that could have resulted from her injuries. Nathalie is now in her early teens and doing very well overall. http://www.davidsfeldmanmd.com/patient-education/case-studies/nathalie-osteogenesis-imperfecta
