摘　　要：双能X线骨密度仪检测骨密度是诊断骨质疏松症的"金标准",学者推荐50岁以上人群采用腰椎前后位进行测量。然而骨质疏松症发病率较高的老年人群,常常合并罹患多种脊柱退行性疾病,例如腰椎间盘突出、退行性侧凸、骨赘增生等,这些病理改变可导致腰椎前后位骨密度值准确性降低。因此,提高腰椎骨密度测量准确性,对于骨质疏松症的诊断和治疗具有重要意义。本文就常见的脊柱退行性疾病对腰椎前后位骨密度的影响作一综述,以期帮助临床医生全面评估和诊断骨质疏松症。Objective Bone mineral density（BMD） detected by dual-energy X-ray absorptiometry can be regarded as the ＂gold standard＂ for the diagnosis of osteoporosis.The scholars recommend that all adults over 50 years old should conduct the anteroposterior position measurement.However,the elderly population with high incidence of osteoporosis often combines with many degenerative spinal diseases,such as intervertebral disc herniation,degenerative scoliosis,osteophyte formation,etc.These pathological changes in the lumbar spine might reduce the accuracy of BMD in anteroposterior position.So the increase of BMD accuracy is of great significance in diagnosis and treatment of osteoporosis.This article reviews the impacts of spinal degenerative diseases on lumbar bone mineral density and aims to facilitate clinicians to assess and diagnose osteoporosis comprehensively.
