摘要
目的 探讨基于三维成像的EOS系统评估胫骨平台后倾角(PTS)对前交叉韧带(ACL)损伤患者的预测价值,并与3种传统X线片测量方法进行对比.方法 回顾分析南京大学医学院附属鼓楼医院2018年10月—2021年12月收治的51例术中确诊为ACL损伤(ACL损伤组)及34例非ACL损伤(对照组)患者的临床资料.通过EOS法、全长法、近端法和后皮质法对患者的PTS进行评估,通过logistic回归分析等统计学方法,探讨不同PTS测量方法对ACL损伤的预测特异性.结果 应用EOS法、全长法和近端法测量ACL损伤组患者的PTS,并与对照组相比,差异有统计学意义(P＜0.05),采用logistic回归分析并构建受试者工作特征(ROC)曲线,曲线下面积(AUC)EOS法(0.955)和全长法(0.657)均优于近端法(0.558)和后皮质法(0.484).对照组和ACL损伤组EOS法和全长法的测量结果均具有相关性(r=0.612,r=0.641).结论 采用EOS系统和基于下肢全长侧位X线片的全长法测量PTS预测ACL损伤的易发性优于近端法和后皮质法,在没有EOS条件的医院,可以使用全长法评估患者的PTS.
Abstract
Objective To investigate the predictive efficacy of posterior tibial slope(PTS)evaluated by the three-dimensional imaging EOS system in patients with anterior cruciate ligament(ACL)injuries,and to compare its perform-ance with three conventional X-ray techniques.Methods A retrospective analysis was conducted on clinical data from 51 patients diagnosed with ACL injury(ACL injury group)and 34 patients without ACL injuries(control group)treated at Nanjing Drum Tower Hospital affiliated to Nanjing University Medical School from October 2018 to December 2021.The PTS was measured using the EOS system,full-length,proximal,and posterior cortical techniques.Logistic regres-sion analysis was employed to investigate the specificity of different methods in predicting ACL injuries.Results The PTS measurements of the ACL injury group by the EOS,full-length,and proximal method were statistically significantly different from those of the control group(P＜0.05).Logistic regression analysis yielded receiver operating characteristic(ROC)curves,with the EOS method achieving an area under the curve(AUC)of 0.955 and the full-length method reaching 0.657,both outperforming the proximal(0.558)and posterior cortex(0.484)methods.There was a correla-tion in the measurements of PTS by the EOS and full-length methods between the control group and the ACL injury group(r=0.612,r=0.641).Conclusions PTS measurements using the EOS system and full-length method based on lateral full-length X-rays are better than the proximal and posterior cortical techniques in predicting the susceptibility to ACL injuries.In hospitals without EOS facilities,the full-length method can serve as a reliable alternative for assessing pa-tients'PTS.
