Objective To discuss the high frequency ultrasound scan method and sonographic features of fibularis long tendon. Methods A total of 120 ankles and feet fibularis longus tendons of normal adults were detected by diagnostic ultrasound equipments and eight methods were used to determinate the cross-sectional area(CSA)of lateal malleolus level fibularis longus tendon (LMLFLT) . Results A detailed description of each section of the fibularis long tendon ultrasonography . The CSA of LMLFLT were (11.4 ± 1.67) mm2 and (9. 72 ± 1. 71) mm2 for male subjects (27 subjects , 54 feet) and female(33 subjects,66 feet). The difference was statistically significant (t = 2. 63 ,P < 0. 05 ). The CSA of LMLFLT of manual workers or sports enthusiasts (21 subjects ,42 feet) was (11. 8 ± 1. 80) mm . The CSA of LMLFLT of left feet (60 feet) and right feet (60 feet) were (10. 42 ± 1. 85 ) mm2 and (10. 30 ± 1. 83 ) mm2. The difference had no statistical significance (t = 0. 02, P > 0. 05 ). The CSA of LMLFLT of non-manual workers or sports enthusiasts ( 39 subjects , 78 feet) was (9. 57 ± 1. 27 ) mm . The difference was statistically significant(t =4. 63 ,P < 0. 05 ). Conclusion The high frequency ultrasound is an ideal way for checking the fibularis longus tendon.%目的 探讨腓骨长肌腱的高频超声检查方法和临床应用价值.方法 对60名健康成年人(共120只足)足及踝部腓骨长肌腱,应用8种腓骨长肌腱全程检查方法进行超声检查,同时测量外踝水平腓骨长肌腱横截面积.结果 获得腓骨长肌腱各个切面的超声声像图.27名男性健康成年人(54只足)外踝水平腓骨长肌腱横截面积为(11.14±1.67) mm2,高于33名女性健康成年人(66只足)的(9.72±1.71) mm2,且差异有统计学意义(t=2.63,P＜0.05);60只左足外踝水平腓骨长肌腱横截面积为(10.42±1.85)mm2,与60只右足的(10.30±1.83)mm2比较差异无统计学意义(t=0.22,P＞0.05);21名体力劳动者或运动爱好者(42只足)外踝水平腓骨长肌腱横截面积为(11.83±1.80)mm2,高于39名非体力劳动者或非运动爱好者(78只足)的(9.57±1.27)mm2,且差异有统计学意义(t=4.63,P＜0.05).结论 高频超声是检查足及踝部腓骨长肌腱的理想方法.
