Osteogenesis imperfecta (OI), also known as brittle bone disease, is a group of genetic disorders that mainly affect the bones. It results in bones that break easily. The severity may be mild to severe. Other symptoms may include a blue tinge to the whites of the eye, short height, loose joints, hearing loss Osteogenesis imperfecta (OI) refers to a heterogeneous group of congenital, non-sex-linked, genetic disorders of collagen type I production, involving connective tissues and bones. The hallmark feature of osteogenesis imperfecta is osteoporosis The prognosis depends upon the type of OI. In type IV, fractures are common and will cause deformity and short stature. If we start the treatment as soon as possible, the prognosis will be better with fewer sequels . Citation: Jorge Sales Marques et al.

Type IA normal teeth Type IB dentiogenesis imperfecta. Type I osteogenesis imperfecta is less severe than other types and most often associated with blue sclerae.There is no cure or drug treatment for OI. Treatments are aimed at increasing overall bone strength to prevent fracture and maintain mobility. Most people with type I and type IV osteogenesis Imperfecta inherited it from their parents who have autosomal dominant disorder.How is Osteogenesis Imperfecta Treated?

Osteogenesis imperfecta (so-called brittle bone disease) is a family of diseases that result from abnormalities in type I collagen (a major component of normal osteoid and bone). From: Elseviers Integrated Pathology, 2007. In osteogenesis imperfecta, the collagen produced is abnormal and disorganized, which results in a number of abnormalities throughout the body, the most notable being fragile, easily broken bones.

There is not yet a cure for OI. Treatment is directed toward preventing or controlling the symptoms, maximizing independent mobility, and developing optimal bone mass and muscle strength.
