多层螺旋CT技术在篮球运动员膝关节损伤诊断中的应用

Application of Multi-slice Spiral CT in the Diagnosis of Knee Joint Injuries of Basketball Players

本文探讨MSCT影像技术在篮球运动员膝关节损伤中的诊断价值。回顾性收集118例膝关节损伤篮球运动员临床资料,均行MSCT检查。结果显示,MSCT膝关节损伤诊断结果与关节镜结果一致性Kappa值为0.837(95%CI:0.704~0.969);篮球运动员患膝后交叉韧带角、后交叉韧带指数小于健膝,外侧胫骨平台倾斜角大于健膝(P<0.05);篮球运动员患膝完全撕裂后交叉韧带角、后交叉韧带指数均小于部分撕裂、正常,外侧胫骨平台斜角大于部分撕裂、正常(P<0.05)。膝关节损伤撕裂程度与后交叉韧带角、后交叉韧带指数呈负相关,与外侧胫骨平台倾斜角呈正相关(P<0.05);三者联合诊断篮球运动员膝关节韧带损伤价值的AUC优于单一诊断。可见MSCT影像技术在篮球运动员膝关节损伤诊断中具有独特优势,可指导临床治疗。

This paper investigated the diagnostic value of MSCT imaging technology in basketball players with knee injuries.The clinical data of 118 cases of basketball players with knee injury were retrospectively collected,and all of them were examined by MSCT.The results showed that the Kappa value of concordance between MSCT knee injury diagnosis and arthroscopic findings was 0.837(95%CI:0.704-0.969).The posterior cruciate ligament angle and posterior cruciate ligament index of the affected knee were smaller than those of the healthy knee and the lateral tibial plateau tilt angle was larger than that of the healthy knee in basketball players(P<0.05).In basketball players with complete tears of the affected knee the posterior cruciate ligament angle and posterior cruciate ligament index were smaller than partial tears and normal,and the lateral tibial plateau oblique angle was larger than partial tears and normal(P<0.05).The degree of knee injury tear was negatively correlated with posterior cruciate ligament angle and posterior cruciate ligament index,and positively correlated with lateral tibial plateau tilt angle(P<0.05).The AUC of the combined value of the three diagnoses of knee ligament injuries in basketball players was superior to that of the single diagnosis.It can be seen that MSCT imaging technology has unique advantages in the diagnosis of knee injuries in basketball players and can guide clinical treatment.
