Transforaminal endoscopic spine surgery is an emerging technique in spine surgery, but it offers 2 distinct challenges to spine surgeons looking to adopt it: 1) targeting spine pathology and 2) understanding the endoscopic anatomy visualized through the endoscope. Intraoperative computed tomography (CT)-guided navigation is also an emerging technique in spine surgery that is becoming widely adopted for its benefits in assisting surgeons in localizing pathology and guided spine instrumentation placement. In this technical note, we describe a technique that uses intraoperative CT-guided navigation concomitantly with a transforaminal endoscopic approach to decompress a L4-L5 foraminal heterotopic bone formation after an oblique lumbar interbody fusion. The addition of intraoperative CT-guided navigation proved beneficial in targeting the pathology during the procedure and ensuring that the pathology was resolved by offering postoperative CT visualization of the decompressed neural foramen.
经椎间孔内窥镜脊柱手术是脊柱外科领域的一项新兴技术，但对于希望采用该技术的脊柱外科医生来说，它带来了 2 个明显的挑战：1）针对脊柱病变，2）理解通过内窥镜观察到的内镜解剖结构。术中计算机断层扫描（CT）引导导航也是脊柱外科领域的一项新兴技术，由于其在帮助外科医生定位病变和引导脊柱器械放置方面的优势，该技术正在被广泛采用。在本技术说明中，我们描述了一种技术，该技术在经椎间孔内窥镜入路的同时使用术中 CT 引导导航，以治疗斜外侧腰椎椎间融合术后 L4-L5 椎间孔异位骨形成的减压。术中 CT 引导导航的加入有助于在手术过程中定位病变，并通过术后 CT 显示减压后的神经孔来确保病变得到解决。
