[A contribution to the recording and study of the disease pattern of osteogenesis imperfecta tarda (author's transl)].

This study aims at investigating in a group of thirty-five patients whether osteogenesis imperfecta tarda presents a uniform disease pattern in respect of clinical and roentgenological criteria, or whether it can be subdivided into clinical groups. Depending on the severity of the disease, it was possible to subdivide this into two groups: a severe form of osteogenesis imperfecta tarda, and a bland form. This subdivision was effected according to the most conspicuous symptom of frequency of the fracture. The other symptoms do not allow any subdivision into groups since their occurrence is independent of the severity of the disease pattern.
