Helfet试验对膝关节半月板损伤诊断的临床意义

Clinical value of helfet test in the diagnosis of meniscus injury

[目的]检查Helfet试验对膝关节半月板损伤诊断的准确性。[方法]运用前瞻性对比研究方法,分析研究2007年4月-2007年10月北医三院收治的外侧半月板损伤患者52例,其中男34例,女18例,平均25.3岁（15～43岁）,内侧半月板损伤23例,其中男14例,女9例。本院外侧半月板患者15例,其中男9例,女6例。内侧半月板患者6例。分别进行Helfet试验检查,依胫骨结节屈伸时是否内外旋来判断半月板损伤,并与麦氏征,摇摆试验,KS征和及关节镜下所见为对照。[结果]所有外侧半月板损伤患者,Helfet试验阳性率81.4%,与半月板其他几个试验麦氏征,KS征,摇摆试验,关节镜的诊断相符合,对于半月板提篮伤及横裂等类型阳性率分别为89.6%、87.2%,对内侧半月板诊断阳性率差。[结论]Helfet试验对外侧半月板损伤的诊断准确率较高,尤对于半月板提篮伤及横裂等引起绞锁症状的前体部为主的患者。而且操作简便、无创、适合推广应用。对内侧半月板诊断阳性率差。

[ Objective ] To study the accuracy of Helfet test in the diagnosis of the knee meniscus tear. [ Method ] From Apr. 2007 to Oct. 2007,52 cases of the lateral meniscus tear and 23 cases of the medial meniscus tear were checked-up with Helfet test,McMurray test , KS test,and arthroscope comparatively. [ Result] The Helfet Test was positive in most of the lateral meniscus tear cases. The consistency with McMurray test and arthroscope was lateral meniscus tear, especially to bucket-handle and Horizontal tear high respectively. The rate of accuracy to lateral menicus was 81.4%. The rate of accuracy to bucket-handle and Horizontal tear were 89.6% and 87.2% respectively. [ Conclusion]The ＂Helfet＂ test is sensitive to the knee lateral meniscus tear. It is fast,simple,reliable,reproducible,positive for diagnose of lateral meniscus tear,and is worth of being used widely.
