Osteogenesis Imperfecta and Child Abuse From a Forensic Point of View.

Osteogenesis imperfecta (OI) also called brittle bone disease is a rare genetic disorder that results from a defect in type 1 collagen, which is a main structural protein involved in the structure of bones, tendons, ligaments, the dentin layer of teeth, and the sclera of the eye.
