RESUMO
Objectives: To assess the prevalences across Europe of radiological indices of degenerative inter-vertebral disc disease (DDD); and to quantify their associations with, age, sex, physical anthropometry, areal BMD (aBMD) and change in aBMD with time. Methods: In the population-based European Prospective Osteoporosis Study, 27 age-stratified samples of men and women from across the continent aged 50+ years had standardized lateral radiographs of the lumbar and thoracic spine to evaluate the severity of DDD, using the Kellgren-Lawrence (KL) scale. Measurements of anterior, mid-body and posterior vertebral heights on all assessed vertebrae from T4 to L4 were used to generate indices of end-plate curvature. Results: Images from 10 132 participants (56% female, mean age 63.9 years) passed quality checks. Overall, 47% of men and women had DDD grade 3 or more in the lumbar spine and 36% in both thoracic and lumbar spine. Risk ratios for DDD grades 3 and 4, adjusted for age and anthropometric determinants, varied across a three-fold range between centres, yet prevalences were highly correlated in men and women. DDD was associated with flattened, non-ovoid inter-vertebral disc spaces. KL grade 4 and loss of inter-vertebral disc space were associated with higher spine aBMD. Conclusion: KL grades 3 and 4 are often used clinically to categorize radiological DDD. Highly variable European prevalences of radiologically defined DDD grades 3+ along with the large effects of age may have growing and geographically unequal health and economic impacts as the population ages. These data encourage further studies of potential genetic and environmental causes.

The study presented here is based on 176 forensic dental reports compiled between 1993 and 2001. The bulk of the research took place in 1997, when major construction at Potsdamer Platz and Lehrter Bahnhof in central Berlin required the excavation of considerable quantities of earth. As building proceeded here, at 'Europe's biggest construction site', it revealed not only a large number of long bones, but also a great many skulls and skull fragments. In five instances, complete skeletons were unearthed. Many of the bones ultimately proved to be of animal origin. The police were not instructed to open a single criminal investigation. Identifying and piecing together the material in this context makes tremendous demands of forensic osteology. Establishing the nature of these finds beyond reasonable doubt, and putting a name and date to them, calls for interdisciplinary co-operation between experts in odontology, anthropology, anatomy, radiology and veterinary medicine, not to mention historians.
