正常踝关节距腓前韧带及跟腓韧带高频超声检测及其临床意义

目的通过高频超声对正常踝关节距腓前韧带及跟腓韧带的检测,总结出正常距腓前韧带、跟腓韧带声像图特征及显示率,评价超声检测距腓前韧带、跟腓韧带的可行性,并探讨其临床应用价值。方法应用高频超声对114例健康志愿者踝关节进行检查,观察距腓前韧带及跟腓韧带的声像图特征,测量其厚度并评价其显示率。结果应用高频超声能较清晰显示距腓前韧带以及跟腓韧带,男女性距腓前韧带的显示及厚度测量均应首选跖屈位,其次中立位,避免在背屈位检查;男女性跟腓韧带的显示及厚度测量均应首选背屈位,其次中立位,避免在跖屈位检查。结论高频超声对踝关节距腓前韧带及跟腓韧带具有良好的显示效果,是一种可行、无创、价廉的检查方法。有望成为踝关节外侧副韧带损伤早期诊断行之有效的诊断手段,具有良好的临床应用价值。

THE EXAMINATION AND ITS CLINICAL SIGNIFICANCE OF ANTERIOR TALOFIBULAR LIGAMENT AND CALCANEOFIBULAR LIGAMENT IN NORMAL PEOPLE THROUGH HIGH -FREQUENCY UTRASONOGRAPHY

Objective To investigate the sonographic features and display rate of the anterior talofibular liga- ment（ATFL） and calcaneofibular ligament（CFL） in normal people through high- frequency ultrasound, to evaluate its clinical application. Methods 114 healthy volunteers were examined ATFL and CFL through high -frequency ul- trasonography for measuring the thickness and display rate of ATFL and CFL. Results High - frequency ultrasonog- raphy can clearly display the ATFL and CFL. To distinct display ATFL and measure the thickness of ATFL, people should be preferred in plantar flexion, secondly in neutral position, but not in dorsiflexion position, while the exami- nation of CFL should be preferred in dorsiflexion position, secondly neutral position and avoid in plantar flexion posi- tion. Conclusion High -frequency uhrasonography is a viable, noninvasive, inexpensive examination method for ATFL and CFL with a distinct display. High - frequency uhrasonography may be an effective diagnostic method in an- kle ioint iniurv for early diagnosis.
