目的 :探讨测量男性腰椎、股骨颈骨密度的临床价值。方法 :对 2 2 4例 2 0～ 74岁成年男性的腰椎和股骨颈行定量 CT骨密度测量 ,并对结果进行分析。结果 :成年男性腰椎和股骨颈骨密度峰值年龄为 2 0～ 2 4岁 ,35岁以后股骨颈骨密度下降速率大于腰椎 ,二者累积丢失率差异具有显著性 ( P<0 .0 5 )。结论 :男性股骨颈的骨密度的测量值较腰椎更具有临床意义。
Objective: To investigate the clinical value of measuring lumbar spine and femoral neck bone mineral density in men. Methods: Quantitative CT bone density measurements were performed on 224 adult men aged 20 ~ 74 years with lumbar spine and femoral neck. The results were analyzed. Results: The peak age of lumbar spine and femoral neck bone mineral density was 20 ~ 24 years old in adults. The decline rate of femoral neck bone mineral density after 35 years old was higher than that of the lumbar vertebra. There was significant difference between the two groups (P <0.05). Conclusion: The measured femoral neck BMD is more clinically significant than lumbar spine.
