To explore the safety and efficacy of transpseudarthrosis osteotomy with interbody fusion in the treatment of Ankylosing Spondylitis (AS) patients with kyphotic spinal pseudarthrosis by a single posterior approach.
Twelve consecutive patients with spinal pseudarthrosis underwent transpseudarthrosis osteotomy and interbody fusion with a polyetheretherketone (PEEK) cage by a single posterior approach. The operative time, intraoperative blood loss, and complications were recorded. Radiographic and clinical results were assessed preoperatively and at the final follow-up.
The average operative time was 201.9 min and the mean blood loss was 817.5 ml. The visual analogue scale (VAS) improved significantly from 6.7 preoperatively to 1.1 at the final follow-up. The average correction of the segmental kyphosis at the level of the pseudarthrosis was 22.3°. Bony fusion was achieved in all patients, and there was no obvious loss of correction at follow-up.
Transpseudarthrosis osteotomy at the level of the pseudarthrosis can be safely performed and surgical repair of pseudarthrosis with interbody fusion by a single posterior approach was feasible.
探讨后路单一切口经椎骨假关节截骨融合治疗强直性脊柱炎（AS）脊柱假关节后凸畸形的安全性和疗效。
连续 12 例脊柱假关节患者采用后路单一切口行经椎骨假关节截骨融合术，使用聚醚醚酮（PEEK） cage 融合。记录手术时间、术中出血量及并发症。术前及末次随访时评估影像学和临床结果。
平均手术时间为 201.9 分钟，平均失血量为 817.5 毫升。视觉模拟评分（VAS）从术前的 6.7 分显著改善至末次随访时的 1.1 分。假关节水平节段后凸的平均矫正角度为 22.3°。所有患者均获得骨性融合，随访时无明显矫正丢失。
后路经椎骨假关节截骨术是安全的，后路单一切口经椎间融合治疗假关节是可行的。
