Arthroscopic ankle arthrodesis (AAA) is a recognised salvage procedure for end-stage arthritis. Its reported disadvantages include a high rate of re-operation for symptomatic prominence of metalwork. We propose that the use of a headless screw would reduce this re-operation rate.
We reviewed 32 AAAs, using the Acutrak™6/7 mm headless screw fixation system, to determine peri-operative parameters and complication rates.
At an average of 22 months follow-up, 28 (88%) had united radiologically. There were 2 stable fibrous non-unions not requiring further intervention. Of the other 2, one was successfully revised using an open technique, and the other patient died of unrelated causes. There were no other complications in this series, with no cases of metalwork removal for prominence or pain.
Using a headless screw fixation for arthroscopic ankle arthrodesis prevents symptomatic metalwork prominence and the requirement for removal.
关节镜下踝关节融合术（AAA）是治疗晚期关节炎的一种公认的挽救性手术。其报道的缺点包括金属突出的症状性再手术率较高。我们提出使用无头螺钉会降低这种再手术率。
我们回顾了 32 例采用 Acutrak™6/7 毫米无头螺钉固定系统的 AAA，以确定围手术期参数和并发症发生率。
平均随访 22 个月，28 例（88%）影像学上融合。有 2 例稳定的纤维性不愈合，无需进一步干预。在其他 2 例中，1 例成功地采用开放技术进行了修正，另 1 例患者因与手术无关的原因死亡。本系列无其他并发症，无因突出或疼痛而去除金属的病例。
关节镜下踝关节融合术采用无头螺钉固定可防止金属突出引起的症状和需要去除的情况。
