This technique guide is intended to help surgeons to avoid pitfalls and optimize the surgical technique for implantation of a total ankle prosthesis.
STEP 1 PREOPERATIVE PLANNING: Obtain radiographs and other relevant images and perform accurate templating.
STEP 2 PATIENT POSITIONING: Position the patient with the foot and patella facing directly forward, and mark the anterior tibial crest.
STEP 3 SURGICAL APPROACH: Incise the ankle, taking care to avoid injury to the superficial peroneal nerve and to protect the deep neurovascular bundle.
STEP 4 BONE CUTS AND COMPONENT IMPLANTATION: Make the bone cuts in the distal part of the tibia and the talar dome, taking care to avoid excessive bone resection from the distal part of the tibia, fracture of the malleoli, or penetrating too deeply.
STEP 5 SOFT-TISSUE BALANCING: Make adjustments as needed for optimal range of motion, alignment, and joint balancing; then remove the trial components and insert the final components.
STEP 6 WOUND CLOSURE: Repair the extensor retinaculum and close the wound, taking measures that help avoid wound-related complications.
RESULTS & PREOP/POSTOP IMAGES: Despite careful patient selection and surgical technique in our series of 106 consecutive total ankle arthroplasties performed with the Agility system, twenty-seven ankles (25%) had problems related to the anterior incision that required local wound care or oral antibiotics and then healed without subsequent consequences.

本技术指南旨在帮助外科医生避免陷阱,并优化全踝关节假体植入的手术技术。
步骤1术前规划:获取X线片和其他相关影像,并进行准确的模板测量。
步骤2患者体位:将患者足部和髌骨直接朝前摆放,标记胫骨前缘。
步骤3手术入路:切开踝关节,注意避免损伤腓浅神经,并保护深部神经血管束。
步骤4截骨与假体植入:在胫骨远端和距骨穹窿部进行截骨,注意避免胫骨远端过度截骨、踝关节骨折或截骨过深。
步骤5软组织平衡:根据需要进行调整,以获得最佳活动范围、对线和关节平衡;然后取出试验假体组件,植入最终假体组件。
步骤6伤口闭合:修复伸肌支持带并闭合伤口,采取措施避免伤口相关并发症。
结果与术前/术后影像:尽管在我们使用Agility系统连续进行的106例全踝关节置换系列手术中,对患者进行了仔细选择并采用了手术技术,但仍有27例踝关节(25%)出现了与前侧切口相关的问题,需要进行局部伤口护理或口服抗生素治疗,随后愈合且无后续不良后果。
