目的 研究超声在跟腱断裂术后并发症的应用。方法 对83例跟腱断裂术后中发生并发症的7例患者进行超声扫查， 观察跟腱的的连续性、腱体的形态、内部回声及腱周软组织的回声，跟腱及腱周软组织的彩色血流、跟腱动态活动 情况等指标。结果 7例发生并发症，总的发生率为8.4%，其中术后感染2例，跟腱再断裂2例，腓肠神经损伤2例， 发生率分别均为2.4%，跟腱粘连1例，发生率为1.2%。各种并发症的超声声像图具有一定的特征性。结论 超声可以 应用于跟腱断裂术后并发症的诊断。

Objective To study the application of ultrasound in postoperative complications of Achilles tendon rupture. Methods 7 complications in 83 cases of postoperative of Achilles tendon rupture were examined by ultrasonography. The continuity , shape , the internal echo, soft tissue around, color blood flow and the dynamic behavior of the Achilles tendon were observed. Results Complications occurred in 7 cases, the total incidence was 8.4%. Among them, 2 cases were postoperative infection, 2 cases were Achilles tendon rupture again, 2 cases were sural nerve injury, the incidence for each was 2.4%, 1 case was Achilles tendon adhesion , the incidence was 1.2%.The sonographic features of various complications have some characteristics. Conclusion Ultrasonography can be used for the diagnosis of postoperative complications of Achilles tendon rupture.
