Some objections to the international nomenclature for constitutional diseases of the bone.

The International Nomenclature of Constitutional Diseases of Bone is criticised and the concept of embryonic osteochondropathy is proposed as an alternative approach. It is claimed for example that the term "constitutional" has no real scientific or, above all, medical meaning. The defects of this "official" nomenclature are highlighted and a slimmer classification system of use in the diagnosis of osteochondroblastic mesenchymopathies is recommended.
