通过对不同程度慢支炎患者６３例锁骨中点骨皮质厚度的测量，分析慢支炎引起骨质疏松的程度。其中单纯慢支炎２０例、慢支炎伴自发骨折２２例、慢支炎肺心病伴自发骨折２１例、同龄健康人２０例为对照。结果表明，随慢支炎程度的加重，锁骨皮质逐渐变薄、骨质疏松患病率也逐渐增加。因而，慢支炎患者的诊断和治疗都不得不考虑骨质疏松的问题。 By measuring the thickness of cortical bone in 63 cases with chronic myositis at different degrees, we analyzed the degree of osteoporosis caused by chronic bronchitis. Among them, 20 cases of simple chronic bronchitis, 22 cases of chronic bronchitis with spontaneous fracture, 21 cases of chronic mycoplasma pneumonia with spontaneous fracture, and 20 healthy people of the same age as the control. The results showed that, with the degree of chronic bronchitis aggravated, the subclavian cortex became thinner and the prevalence of osteoporosis gradually increased. Therefore, the diagnosis and treatment of patients with chronic myelitis have to consider the issue of osteoporosis.
