Classification of osteogenesis imperfecta.

Type	DI	Clinical severity	Typical features
I	−	Mild, nondeforming OI	Normal height or mild short stature; blue sclera
II	?	Perinatal lethal	Multiple rib and long bone fractures at birth; pronounced deformities; broad long bones; low density of skull bones on radiographs; and dark sclera
III	+	Severely deforming	Very short; triangular face; severe scoliosis; and grayish sclera
IV	+	Moderately deforming	Moderately short; mild-to-moderate scoliosis; and grayish or white sclera
V	−	Moderately deforming	Mild-to-moderate short stature; dislocation of radial head; mineralized interosseous membrane; hyperplastic callus; and white sclera
VI	−	Moderate-to-severe deforming	Moderately short; scoliosis; accumulation of osteoid in bone tissue, fish-scale pattern of bone lamellation; and white sclera
