摘　　要：目的 探讨定量CT测量分析髋部脆性骨折患者腰椎与股骨近段骨密度的相关性。方法 选取100例髋部脆性骨折作为观察组,另外选取同期接受健康体检的50例健康志愿者作为对照组,均接受定量CT测量骨密度,同时利用Pearson相关分析进行统计分析腰椎与股骨近段骨密度的关系。结果 观察组患者腰椎L_(1)、L_(2)、L_(3)、L_(4)定量CT骨密度检测值均低于对照组,差异有统计学意义(P<0.05);观察组股骨近段CT骨密度低于对照组,差异有统计学意义(P<0.05);髋部脆性骨折患者股骨近段定量CT骨密度与腰椎L_(1)、L_(2)、L_(3)、L_(4)定量CT骨密度检测值呈正相关(P<0.05)。结论 定量CT可给予髋部脆性骨折患者较精确的骨密度检查,其中腰椎与股骨近段骨密度的关系为正相关,即腰椎骨密度低则股骨近段骨密度越低,髋部脆性骨折发生风险越高。Objective To analyze the relationship between bone density of the lumbar spine and proximal femur in the analysis of hip fracture populations with quantitative CT.Methods 100 cases of hip brittle fractures admitted to our hospital from December 2020 to December 2022 were selected as case group research subjects,and 50 healthy individuals who underwent health examinations during the same period were selected as control group research subjects;All patients included in the study received quantitative CT measurements of bone density in the lumbar spine and proximal femur,and statistical analysis was conducted using Pearson correlation analysis,analyzed the relationship between bone density in the lumbar spine and proximal femur.Results The quantitative CT bone density detection values of lumbar spine L_(1),L_(2),L_(3),and L_(4) in the case group were lower than those in the control group,with statistical significance(P<0.05);The CT bone density of the proximal femur in the case group was higher than that in the control group,with a statistically significant difference(P<0.05);The quantitative CT bone density of the proximal femur in patients with hip fracture was positively correlated with the bone density detection values of lumbar spine L_(1),L_(2),L_(3),and L_(4)(P<0.05).Conclusion Quantitative CT can provide a more accurate bone density examination for people with hip brittle fractures,with a positive correlation between the bone density of the lumbar spine and the proximal femur.That is,if the bone density of the lumbar spine is low,the bone density of the proximal femur is lower,and the risk of hip brittle fractures is higher.
