Abstract

Over the past decade, minimally invasive sacroiliac joint (SIJ) fusion has become an effective treatment for patients suffering from low back pain (LBP) originating from the SIJ. Perioperative C-arm fluoroscopy-assisted surgical navigation during SIJ fusion remains challenging due to the lack of 3D spatial information. This study developed and assessed a 3D CT/2D fluoroscopy integration approach based on digitally reconstructed radiographs (DRRs) obtained from pre-operative CT scans. Development of this approach proved feasible and landmarks were successfully translated, in retrospect, to perioperatively acquired fluoroscopies. Further expansion of and research into the proposed approach to increase perioperative navigation is indicated and additional validation should be performed.

摘要

在过去的十年中，微创骶髂关节 (SIJ) 融合术已成为治疗源自 SIJ 的腰痛 (LBP) 患者的有效方法。由于缺乏 3D 空间信息，围手术期 C 臂透视辅助手术导航在 SIJ 融合期间仍然具有挑战性。本研究开发并评估了一种基于从术前 CT 扫描获得的数字重建射线照片 (DRR) 的 3D CT/2D 透视集成方法。这种方法的发展被证明是可行的，回想起来，地标成功地转化为围手术期获得的透视。建议进一步扩展和研究增加围手术期导航的拟议方法，并应进行额外的验证。
