Brittle Bone disease also known as Osteogenesis Imperfecta, shows little symptoms except a few facial characteristics that stand out. Legs and arms can be short or deformed, as can also be the stature of the sufferer. Many sufferers have malformed backs with diseases such as scoliosis and a humped spine. Many affected suffer from different chest deformations such as Pectus Carinatum or Pectus Excavatum. Pectus Carinatum is a condition where the chest is round and protruding out, and the opposite is Pectus Excavatum, a condition where the chest is caved in. Sufferers of Brittle Bone disease have feet which are flat with no arch. Joints are flat and very lax. Bruises come about too easily and often with little or no contact. Legs are bowed.
