["In utero" diagnosis of congenital fragilitas ossium (osteogenesis imperfecta) (author's transl)]. / Diagnostic "in utéro" d'une fragilité osseuse congénitale.

The authors report a case of congenital fragilitas ossium diagnosed "in utero". The radiography of the fetus in the uterus showed bony abnormalities suggestive of Porak and Durante's disease. This early diagnosis is often useful because it will help to prevent trauma before and during delivery which is a principal cause of fetal death.
