Study Design Retrospective case series. Objective The objective of this study is to describe an alternative technique to attain interbody lumbar fusion in the event of pseudarthrosis after axial lumbar interbody fusion (AxiaLIF) and to assess its safety. Methods Three patients who suffered from pseudarthrosis after AxiaLIF underwent revision surgery with a DEVEX cage (DePuy Synthes, Raynham, MA, United States) through an anterior approach. We report technical details as well as clinical and radiological results at 12 months follow-up. Results Preoperative symptoms resolved in all cases. There were no perioperative complications. One patient had a deep venous thrombosis at postoperative day 9. A decrease in visual analog scale score for pain was observed, from 8.67 preoperatively to 2 postoperatively at final follow-up. Radiographic workup after 12 months showed no sign of implant failure or loosening, and fusion was obtained in all cases. Conclusion Anterior fusion with a DEVEX cage in front of a TranS1 screw (TranS1 screw, Inc., Wilmington, North Carolina, United States) for AxiaLIF pseudarthrosis is safe and effective.
回顾性病例系列研究。目的：本研究的目的是描述一种在轴向腰椎椎间融合术（AxiaLIF）后假关节形成时实现腰椎椎间融合的替代技术，并评估其安全性。方法：3例AxiaLIF术后发生假关节的患者通过前路使用DEVEX椎间融合器（美国马萨诸塞州雷纳姆市DePuy Synthes公司）进行翻修手术。我们报告技术细节以及随访12个月时的临床和影像学结果。结果：所有病例术前症状均得到缓解。无围手术期并发症。1例患者在术后第9天发生深静脉血栓形成。末次随访时，疼痛视觉模拟评分从术前的8.67降至术后的2。12个月后的影像学检查未显示植入物失败或松动迹象，所有病例均实现了融合。结论：对于AxiaLIF假关节，在TranS1螺钉（美国北卡罗来纳州威尔明顿市TranS1螺钉公司）前方使用DEVEX椎间融合器进行前路融合是安全有效的。
