Osteogenesis imperfecta
Description
A group of disorders passed through families in which bones break easily, sometimes for no known reason.
Overview
Osteogenesis imperfecta is caused by gene changes. These genes affect how the body makes a protein called collagen that is needed for bone strength. There are a number of types of the condition, ranging from mild to severe.
Symptoms
Symptoms depend on type. Symptoms can be mild, with only a few broken bones in a lifetime. Some people have hundreds of broken bones in their lifetime, including in the womb. Some babies die at birth or shortly after birth.
Treatments
Treatments include bone-strengthening medicines and occupational and physical therapy. Many children have orthopedic surgery to place metal rods into bones to make them stronger.
