MSCT临床应用于肌健、韧带闭合性损伤的诊断价值分析与评价

Value Analysis and Evaluation on Diagnosis of MSCT Clinically Applied in Muscle and Ligament Closed Injuries

目的研究多层螺旋CT在肌健、韧带闭合性损伤临床诊断中的应用价值。方法选取我院骨科收治的韧带损伤或(和)肌腱闭合性损伤患者共100例,作为观察组;另将100例健康者作为健康组。所有入选对象均接受16层螺旋CT扫描,并将观察组扫描结果与手术结果比较,对比损伤膝关节后交叉韧带与正常膝关节后交叉韧带的多层螺旋CT影像特征。结果与手术结果比较,多层螺旋CT诊断肌腱损伤正确率为71.15%,诊断韧带损伤正确率为93.75%。与健康组膝关节后交叉韧带多层螺旋CT影像特征相比,损伤的膝关节后交叉韧带角、厚度更小,长径更短,均为P<0.05,差异有统计学意义。本次CT检查显示肌腱损伤患者均存在肌腹肿胀、肌腱迂曲、肌腱增粗等表现,韧带损伤患者均存在韧带迂曲、边界模糊、增粗、关节腔积液等表现。结论多层螺旋CT为肌腱、韧带闭合性损伤的重要诊断手段,诊断正确率较高;通过淤血、水肿等情况显示损伤范围及程度,是否有关节腔积液,为临床诊断与治疗提供有力依据,可作为该类损伤的首选诊断方法。

Objective This paper is to investigate the application value of multi-slice CT in clinical diagnosis of muscle and ligament closed injuries. Methods A total of 100 patients with tendon injuries or （and） ligament closed injuries admitted by the Orthopaedics Department of the Hospital were selected into the observation group, and another 100 healthy candidates were selected into the health group. All candidates underwent 16-slice spiral CT scanning, and scanning results was compared to surgical results of patients, multi-slice CT imaging features of posterior cruciate ligament with injured kneel joints and those of posterior cruciate ligament with normal knee joints were compared. Results The accuracy of multilayer spiral CT in the diagnosis of tendon injuries hit 71.15% in the comparison in surgical results, and the accuracy in diagnosis of ligament damage hit 93.75%.Compared to multi-slice CT imaging characteristics of post cruciate ligament in the health group, the post cruciate ligament angle of injured kneel joint with smaller thickness and shorter lathy diameter satisfied P〈0.05, and the differences were statistically significant. The results of CT examinations showed that patients with muscle tendon injuries suffered from abdominal symptoms including the swelling, tendon circuity, tendon thickening and patients with ligament injuries suffered from ligament circuity, fuzzy and thickened boundary, articular cavity effusion and other symptoms. Conclusion MSCT acts important diagnosis means for tendon and ligament closed injuries, it delivers diagnostic accuracy, it shows the scope and degree of congestion and edema and the availability of joint cavity effusion, and provides powerful basis for clinical diagnosis and treatment, being preferred diagnostic method of such injury.
