Osteogenesis Imperfecta (OI)-- commonly known as the "brittle bone" disorder-- is a genetic disorder characterized by bones that break easily, often from little or no apparent cause. A person with OI may break a rib while coughing, or a leg by rolling over in their sleep. OI has been documented in all ethnic groups, and affects a person throughout their lifetime
