In this study, the authors aimed to describe a new technique of sacroiliac joint (SIJ) fusion using a robotic navigation guidance system and to document clinical results with patient-reported visual analog scale (VAS) scores.
Patients diagnosed with SIJ dysfunction were surgically treated using 2 hydroxyapatite (HA)-coated, threaded screws with the aid of the robotic navigation system. In a total of 36 patients, 51 SIJs were fused during the study period. Patients' VAS scores were used to determine clinical improvement in pain. Postoperative imaging at routine intervals during the follow-up period was also performed for assessment of radiological fusion. In addition, complication events were recorded, including reoperations.
All 36 patients had successful fusion evidenced by both CT and clinical assessment at the final follow-up. Two patients underwent reoperation because of screw loosening. The mean preoperative VAS score was 7.2 ± 1.1, and the mean 12-month postoperative VAS score was 1.6 ± 1.46. This difference was statistically significant (p < 0.05) and demonstrated a substantial clinical improvement in pain.
Robotic navigation-assisted SIJ fusion using 2 HA-coated, threaded screws placed across the joint was an acceptable technique that demonstrated reliable clinical results with a significant improvement in patient-reported VAS pain scores.
本研究旨在描述一种使用机器人导航引导系统进行骶髂关节 (SIJ) 融合的新技术，并通过患者报告的视觉模拟量表 (VAS) 评分记录临床结果。
诊断为 SIJ 功能障碍的患者在机器人导航系统的辅助下接受了 2 羟基磷灰石 (HA) 涂层、螺纹螺钉的手术治疗。在研究期间，共有 36 名患者的 51 个 SIJ 接受了融合。患者的 VAS 评分用于确定疼痛的临床改善。在随访期间的常规间隔还进行了术后影像学检查，以评估影像学融合。此外，还记录了并发症事件，包括再次手术。
所有 36 名患者在最终随访时均通过 CT 和临床评估成功融合。有 2 名患者因螺钉松动而再次手术。术前 VAS 评分的平均值为 7.2 ± 1.1，术后 12 个月的 VAS 评分为 1.6 ± 1.46。这一差异具有统计学意义 (p < 0.05)，表明疼痛的临床改善显著。
使用 2 个 HA 涂层、螺纹螺钉穿过关节进行机器人导航辅助 SIJ 融合是一种可接受的技术，可通过患者报告的 VAS 疼痛评分显著改善获得可靠的临床结果。
