目的：应用高分辨率超声检测无症状对照和慢性跟腱炎症或部分撕裂运动员肌腱微撕裂的数目和分布。方法：随机记录19例无症状志愿者、16例有症状的慢性跟腱炎运动员和8例部分跟腱断裂运动员的肌腱三个横断面的平均微撕裂数。对照组约67%的肌腱无微撕裂，28%的肌腱有单个微撕裂。慢性跟腱炎组和跟腱部分断裂组中只有18%的运动员跟腱中1/3处无微撕裂。在慢性肌腱炎的肌腱中，13%的肌腱每节有3个以上的微撕裂，而在部分断裂的肌腱中，这一比例增加到87%。结论-微撕裂的形成与跟腱断裂有关。
Objective-To assess the number and distribution of tendon microtears in asymptomatic controls and athletes with chronic Achilles tendinitis or partial thickness tears using high resolution ultrasound.Methods-The mean number of microtears in three random tendon cross sections were recorded per tendon third in 19 asymptomatic volunteers, 16 athletes with symptomatic chronic Achilles tendinitis, and eight athletes with partial Achilles tendon rupture.Results-Microtears were most numerous in the middle third section of the Achilles tendon. Some 67% of tendons in the control group had no microtears, and 28% showed a single microtear. Only 18% of the athletes with chronic Achilles tendinitis and none of the athletes with partial tendon rupture were without microtears in the middle third of their Achilles tendon. Of the tendons with chronic tendinitis, 13% had more than three microtears per section which increased to 87% in tendons exhibiting partial rupture.Conclusions-There appears to be an association between microtear formation and Achilles tendon rupture.
