The bone mineral content and the ultimate compressive strength were determined in 109 fresh lumbar vertebrae from 36 different subjects, 31 to 79 years of age. The degree of macroscopic disc degeneration and the types of fracture were determined. Three types of fracture-central, wedge and transverse-were found, but only under magnification and at simultaneous movements of the fracture segment. The central type of fracture was found predominantly in specimens with high bone mineral content surrounded by normal discs. The wedge type of fracture was consistent with lower bone mineral content and more severe disc degeneration.
对来自36名年龄在31至79岁之间不同受试者的109个新鲜腰椎椎体测定了骨矿物质含量和极限抗压强度。确定了宏观椎间盘退变程度和骨折类型。发现了三种骨折类型——中央型、楔形和横断型——但仅在放大以及骨折节段同时移动的情况下才能发现。中央型骨折主要见于骨矿物质含量高且周围椎间盘正常的标本中。楔形骨折类型则与较低的骨矿物质含量和更严重的椎间盘退变相关。
