正常成人踝关节侧副韧带超声扫查方法学探讨

Ultrasonographic Methodology in Ankle Ligaments in Normal People

目的探讨踝关节各侧副韧带高频超声检查的扫查方法。方法在尸体标本超声扫查的基础上,对100例正常成人踝关节各侧副韧带进行高频超声扫查,观察各韧带的声像特点,测量各韧带的厚度。结果探头在内踝(或外踝)分别与舟骨、距骨前部、距骨后部、跟骨外侧、跟骨载距突间作扇形扫查,能分别较好地显示踝关节胫舟、胫距前、胫跟、跟腓、距腓前、胫距后、距腓后韧带。正确分辨各骨性标志是准确辨别踝关节各侧副韧带的基础。韧带厚度的左右两侧间、男女间分别比较,差异均无显著意义。结论高频超声能较好显示踝关节各侧副韧带,是一种无创、价廉的检查方法。

Objective To explore the methods of ultrasonography in ankle ligaments. Methods Based on cadaver specimens, the characterstics of each ligament in ultrasonographic images were observed and the thickness of these ankle ligaments were measured with high frequency ultrasound in 100 healthy persons. Results The ankle ligaments were obviously displayed at particular sectional planes. Discerning the anatomic structure of the bones correctly was the base of recognizing the ankle ligaments accurately. There was no statistical difference of the thickness between left and right ankle ligaments. There was no statistical difference of ankle ligament thickness between men and women. Conclusions High frequency ultrasound is a noninvasive and cheap method for imaging ankle ligaments.
