NWI和NSI对跆拳道运动致前交叉韧带断裂的诊断分析

doi:10.7517/issn.1674-0475.220134

摘要/Abstract

摘要： 本文探讨MRI髁间窝宽度指数（NWI）、髁间窝形态指数（NSI）在跆拳道运动致前交叉韧带（ACL）断裂诊断中的价值及临床意义。选取82例跆拳道运动致ACL断裂患者作为研究对象，以患侧膝关节为断裂组，健侧膝关节为正常组。采用MRI技术对膝关节进行扫描，测量髁间窝高度（ICH）、髁间窝宽度（ICW）、股骨髁宽度（EW），计算NWI和NSI。结果显示，断裂组ICW、NWI、NSI水平均低于正常组（P<0.05）；NWI、NSI与跆拳道运动致ACL断裂的发病显著相关（P<0.05）；NWI、NSI联合诊断的曲线下面积（AUC）为0.911，诊断特异度为81.71%，敏感度为91.46%；治疗后康复患者NWI、NSI水平均高于未康复患者（P<0.05）；跆拳道运动致ACL断裂患者NWI、NSI与治疗效果呈正相关（P<0.05）。由此可知，MRI测量NWI、NSI在跆拳道运动致ACL断裂诊断方面具有一定价值，且与患者疗效显著相关。

Abstract: This study explored the value and clinical significance of MRI measurement of intercondylar fossa width index (NWI) and intercondylar fossa shape index (NSI) in the diagnosis of anterior cruciate ligament (ACL) rupture caused by taekwondo. 82 patients with ACL rupture caused by taekwondo were selected as the research objects. The affected knee joint was taken as the fracture group and the healthy knee joint was taken as the normal group. MRI was used to scan the knee joint, measure the height of intercondylar fossa (ICH), width of intercondylar fossa (ICW) and width of femoral condyle (EW), and calculate NWI and NSI. The results showed that the levels of ICW, NWI and NSI in the fracture group were lower than those in the normal group (P<0.05). NWI and NSI were significantly correlated with the incidence of ACL rupture caused by taekwondo (P<0.05). The area under the curve (AUC) of the combined diagnosis of NWI and NSI was 0.911, the diagnostic specificity was 81.71%, and the sensitivity was 91.46%. After treatment, the levels of NWI and NSI in rehabilitated patients were higher than those in non-rehabilitated patients (P<0.05). NWI and NSI in patients with ACL rupture caused by taekwondo were positively correlated with the treatment effect (P<0.05). Therefore, MRI measurement of NWI and NSI has certain value in the diagnosis of ACL rupture caused by taekwondo, and is significantly related to the curative effect of patients.
