o. imperfecta. An inherited disorder of connective tissue characterized by defective bone matrix with calcification occurring normally on whatever matrix is present. Clinical findings are multiple fractures with minimal trauma, blue sclerae, early deafness, opalescent teeth, tendency to capillary bleeding, translucent skin, and joint instability. Although the disease is heterogeneous, two different classifications of osteogenesis imperfecta are still used for clinical distinction: osteogenesis imperfecta congenita with early fractures occurring even in utero; and osteogenesis imperfecta tarda with delayed onset of fracturing and much milder manifestations. Healing of bone fractures progresses normally. Later in life, the tendency to fracture decreases and often disappears.-The vast majority of cases are inherited as an autosomal dominant trait, although a small percentage of congenital cases are transmitted as an autosomal recessive. There is no known cure for osteogenesis imperfecta; therefore, treatment is supportive and palliative.
