Minimally invasive repair is a better option for Achilles tendon rupture with low re-rupture and wound-related complications than conservative treatment or traditional open repair. The major problem is sural nerve injury. The purpose of this study was to evaluate the effect and advantage of the intraoperative ultrasonography assistance for minimally invasive repair of the acute Achilles tendon rupture. A retrospective study was performed on 36 cases of acute Achilles tendon rupture treated with minimally invasive repair assisted with intraoperative ultrasonography from January 2015 to December 2017. The relationship of the sural nerve and small saphenous vein was confirmed on the preoperative MRI. The course of the small saphenous vein and the sural nerve was identified and marked by intraoperative ultrasonography. The ruptured Achilles tendon was repaired with minimally invasive Bunnell suture on the medial side of the small saphenous vein (SSV). All patients were followed up for at least 12 months. No sural nerve injury or other complications was found intraoperatively and postoperatively. All the patients returned to work and light sporting activities at a mean of 12.78 ± 1.40 weeks and 17.28 ± 2.34 weeks, respectively. The Mean American Orthopaedic Foot & Ankle Society (AOFAS) scores improved from 59.17 ± 5.31 preoperatively to 98.92 ± 1.63 at the time of 12 months follow-up. There was a statistically significant difference (P < 0.001). No patient complained of a negative effect on their life. The minimally invasive repair assisted with intraoperative ultrasonography can yield good clinical outcomes, less surgical time, and less complications, especially sural nerve injury. It is an efficient, reliable, and safe method for acute Achilles tendon (AT) rupture.

术中超声检查有助于微创修复跟腱破裂。

与保守治疗或传统的开放式修复相比，微创修复是跟腱断裂少，再破裂和并发症相关并发症少的更好选择。主要问题是腓肠神经损伤。这项研究的目的是评估术中超声检查对急性跟腱断裂微创修复的效果和优势。2015年1月至2017年12月，对36例急性跟腱断裂行微创修复辅助术中超声检查的患者进行回顾性研究。术前MRI证实了腓肠神经与小隐静脉的关系。通过术中超声检查来识别并标记小隐静脉和腓肠神经的走向。用微创Bunnell缝线在小隐静脉（SSV）的内侧修复了跟腱断裂。所有患者均接受了至少12个月的随访。术中和术后均未发现腓肠神经损伤或其他并发症。所有患者平均恢复工作和轻度运动的时间分别为12.78±1.40周和17.28±2.34周。美国平均矫形足踝学会（AOFAS）评分从术前的59.17±5.31提高到12个月随访时的98.92±1.63。差异有统计学意义（P <0.001）。没有患者抱怨对其生活有负面影响。借助术中超声检查进行的微创修复可产生良好的临床效果，减少手术时间并减少并发症，特别是腓肠神经损伤。这是一种有效的，可靠和安全的方法，用于急性跟腱断裂。
