To assess the value of ultrasound in imaging the plantaris tendon, ultrasounds were done on 26 legs in 25 patients who had a variety of surgical procedures on the posterior leg. Eighteen ultrasounds were done and interpreted before operation and eight after operation by a radiologist. The sonographic results were compared with the status of the plantaris as determined at surgery. The plantaris was present in 21 of 23 patients for a prevalence of 91%. Eighteen plantaris tendons were well visualized on ultrasound for a sensitivity of 86%. Of the three false-negative results, two occurred with thinned plantaris tendons that were less than 2 mm thick and hence considered inadequate for grafting. Therefore, the sensitivity for detecting a tendon suitable for grafting was 95%. All patients with positive studies had a plantaris tendon present for a specificity of 100%. A learning curve for the radiologist was demonstrated. Ultrasound appears to be effective in the preoperative imaging of the plantaris tendon.
为评估超声对跖肌腱成像的价值，对25例接受了各种小腿后部手术的患者的26条腿进行了超声检查。18次超声检查在术前由一名放射科医生完成并解读，8次在术后完成。将超声检查结果与手术中确定的跖肌状态进行比较。23例患者中有21例存在跖肌，患病率为91%。18条跖肌腱在超声下清晰可见，敏感性为86%。在3例假阴性结果中，2例发生在厚度小于2mm的变薄跖肌腱，因此被认为不适合用于移植。因此，检测适合移植的肌腱的敏感性为95%。所有检查结果为阳性的患者均有跖肌腱存在，特异性为100%。显示了放射科医生的学习曲线。超声似乎在跖肌腱的术前成像中有效。
