Abstract

The lethal form of osteogenesis imperfecta must be more clearly defined than it is. Early death of the child is not a sufficient criteria since it is observed in other forms compatible with survival. The authors therefore insist on the innumerable fractures of the ribs giving the particular aspect described as "bamboo ribs". These are observed in practically all cases. Heterogeneity however is undoubtful and an X-ray film is reproduced showing thin ribs without fractures in another exceptional lethal form. Genetic and very recent biochemical investigations suggest a new heterogeneity of the lethal form, even well defined clinically and radiologically. Contrary to earlier and frequent statements, it results most often from a dominant mutation, while recessive inheritance is much rarer, therefore the overall risk of recurrence much below 25%.
