Fatigue fracture of human lumbar vertebrae under cyclic axial compressive load is investigated between 1 and 5000 load cycles and for load magnitudes between 30 and 70% of the ultimate compressive strength of human lumbar vertebrae. In addition, it is shown that the ultimate compressive strength of human lumbar vertebrae can be predicted from trabecular bone density determined by quantitative computed tomography in combination with a measurement of the area of the vertebral end plate.
研究了人体腰椎在1至5000次循环轴向压缩载荷下以及载荷大小为人体腰椎极限抗压强度的30%至70%时的疲劳骨折情况。此外，研究表明，结合定量计算机断层扫描测定的小梁骨密度和椎体终板面积测量结果，可以预测人体腰椎的极限抗压强度。
