title: [Osteogenesis imperfecta cystica (Fairbank)--a special form of osteogenesis imperfecta congenita (Vrolik) (author's transl)].
abstract: Two patients, aged 13 and 19 years, with osteogenesis imperfecta congenita (Vrolik) have been seen at the rehabilitation centre at Neckargemund. The younger patient showed the typical appearances of osteogenesis imperfecta cystica (Fairbank), while the older patient failed to show these changes in the skeleton. Contrary to the frequently expressed view that patients with osteogenesis imperfecta congenita always die in the perinatal period, they may survive for a considerable length of time. The change of osteogenesis imperfecta congenita (Vrolik) into osteogensis imperfecta cystica (Fairbank) has been described as a sequence in the occasional survivors by Spranger, but is not a necessary condition for survival. Osteogenesis imperfecta cystica should be regarded as an extremely rare special type of Vrolik's disease.
