[On the diagnosis of so-called "constitutional" bone diseases].

The authors review the diagnosis process of so-called "constitutional" bone diseases. They criticize the nomenclature and international classification of them and suggest a diagnostic classification which is virtually independent of structural and metabolic criteria: based on the site and extent of pathological manifestations. The paper also examines the term "dysmorphia", given that it is the shape of the bone segment which initially attracts and guides the clinical diagnosis of embryonal osteochondropathies and suggest it.
