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.
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.
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.
There appears to be an association between microtear formation and Achilles tendon rupture.
使用高分辨率超声评估无症状对照组以及患有慢性跟腱炎或部分厚度撕裂的运动员中肌腱微撕裂的数量和分布情况。
记录19名无症状志愿者、16名有症状的慢性跟腱炎运动员以及8名部分跟腱断裂运动员每条肌腱三分之一区域内三个随机肌腱横切面中的微撕裂平均数量。
跟腱中三分之一区域的微撕裂数量最多。对照组约67%的肌腱没有微撕裂，28%有单个微撕裂。患有慢性跟腱炎的运动员中，只有18%在跟腱中三分之一区域没有微撕裂，而部分肌腱断裂的运动员中没有一个在该区域没有微撕裂。在患有慢性跟腱炎的肌腱中，13%每切面有超过三个微撕裂，在出现部分断裂的肌腱中这一比例增至87%。
微撕裂形成与跟腱断裂之间似乎存在关联。
