title: [Vertebral trabecular bone in various age groups and in osteoporosis-- morphometry and bone matrix biochemistry].
abstract: Vertebral trabecular bone was analysed by morphometry and bone matrix biochemistry. Trabecular bone volume (TBV) and mean trabecular plate thickness (MTPT) decreased with age. TBV was significantly correlated with MTPT and mean trabecular plate density (MTPD). The individual structure of trabecular bone could be described by both MTPT and MTPD together, but changes of these parameters, that were pathognomonic for osteopenia, were not found. By measuring TBV 3 cases of severe osteopenia were identified (TBV less than 2s of controls); 2 of them showed matrix abnormalities so far not described. In one case (a 67 year old woman without risk factors for osteoporosis) an abnormal high content of type III collagen was found, in the other case (a 44 year old woman with acromegaly) bone matrix analysis atypically revealed a significant fraction of type II collagen. Further studies will be needed to assess the pathogenetic or diagnostic importance of these new findings.
