Abstract
Objective To investigate CT values of cancellous bone in femoral neck in adults over 60 years with proximal femoral fractures.Methods From January 2020 to December 2020,a retrospective analysis was performed on 280 subjects aged 60 years or older who underwent bilateral hip CT examination,including 85 males and 195 females,120 on the left side and 160 on the right side,aged 75(66,82)years old.One hundred thirty-six patients with proximal femoral fractures were included in study group and 144 patients without fractures were included in control group.GEOptima CT was used to scan and recon-struct horizontal,coronal and sagittal layers of proximal femur.CT values of cancellous bone in femoral neck were measured and compared between two groups.The relationship between CT values of cancellous bone of femoral neck and proximal femoral fracture was analyzed statistically.Results In terms of age,fracture group aged 79(73.3,85.0)years old,non-fracture group aged 69.5(64.0,78.8)years old,and had significant difference in age between two groups(P＜0.05).In terms of CT value,regional CT value in fracture group was 8.62(-3.62,27.15)HU,which was lower than that in non-fracture group 34.31(-5.93,71.74)HU(P＜0.05).CT value on coronal view in fracture group was-8.48(-30.96,17.46)HU,which was low-er than that in non-fracture group 40.49(5.55,80.71)HU(P＜0.05).CT value on sagittal view in fracture group was-31.28(-54.91,-5.11)HU,which was lower than that in non-fracture group 7.74(-20.12,44.54)HU(P＜0.05).CT values on hori-zontal view in fracture group was 0.17(-23.13,24.60)HU,which was lower than that in non-fracture group 46.40(10.42,85.18)HU(P＜0.05).The mean regional CT values among three planes in the fracture group were lower than those in the non-fracture group.Logistic regression analysis showed coronal CT value was influencing factors of proximal femoral frac-ture,and it could be written into regression equations that predict probability of fracture.Conclusion In adults aged over 60 years old,CT values of cancellous bone of femoral neck decreased with increasing age.The smaller CT value of cancellous bone of femoral neck,the greater risk of proximal femoral fracture.关键词
