Abstract

Radiographic, mineralogic and histomorphometric investigations of the distal radial metaphyses were performed in a group of 57 men who sustained sudden death. The radiographic image of bone structure was assessed by nude eye and with computerized analyses of the microdensitometric curves. Mineral in bone specimens content was estimated by Dulce method. Trabecular mineralized bone area (Vmin), osteoid area (Vos) and trabecular width (dt) were measured on undecalcified sections. Decrease of bone mineral content and Vmin were noted with the age of those investigated. This process affected the radiographic image of bone structure. The radiographic picture of bone structure depends mostly on the mineral content and to a smaller extent on histomorphometric parameters. Microdensitometric measurements make objective assessment of bone structure on the radiograph possible.

摘要

对57名猝死男性的桡骨远端干骺端进行了影像学、矿物学和组织形态计量学研究。通过肉眼和对微密度计曲线的计算机分析来评估骨结构的放射影像。采用杜尔塞法估算骨标本中的矿物质含量。在未脱钙切片上测量小梁矿化骨面积(Vmin)、类骨质面积(Vos)和小梁宽度(dt)。研究发现,随着研究对象年龄的增长,骨矿物质含量和Vmin降低。这一过程影响了骨结构的放射影像。骨结构的放射影像主要取决于矿物质含量,在较小程度上取决于组织形态计量学参数。微密度计测量使得对X线片上的骨结构进行客观评估成为可能。
