腰椎间盘和小关节的退行性改变以及骨质疏松症,是影响上了年纪的人生活质量的两个重要因素。以前多认为退行性改变是骨密度增高,而骨质疏松则是骨密度减低,两者在同一个病人身上存在较少。至于这两者之间的联系,以前主要是用单光子衰减仪测定骨密度的方法对髋关节和腕关节进行了研究,得知髋关节有退行性改变的病人,其腰椎骨质疏松症的发病率亦低;而有骨质疏松症的患者,其髋关节退行性 Degenerative changes in lumbar intervertebral discs and facet joints and osteoporosis are two important factors affecting the quality of life of older people. Before the more that degenerative changes is the increase of bone mineral density, osteoporosis is the reduction of bone mineral density, both in the same patient there is less. As for the link between the two, the previous study mainly focused on the measurement of bone mineral density using a single-photon decay meter. The study of the hip joint and the wrist joint revealed that patients with degenerative changes in the hip joint had osteoporosis The incidence is also low; and patients with osteoporosis, the hip degenerative
