The percutaneous endoscopic technique through an interlaminar approach is a commonly used minimally invasive procedure in the treatment of lumbar disc herniation, even lumbar spinal stenosis. This report describes complete decompression with the percutaneous endoscopic technique for patients with thoracic ossification of the ligamentum flavum (OLF).
We performed surgical decompression in of 2 patients with thoracic myelopathy caused by OLF using percutaneous endoscopic surgery through an interlaminar approach. After surgery, the patients described significant improvement in their preoperative neurologic symptoms. Postoperative thoracic computed tomography showed that the ossification of ligaments was completely removed.
We applied the percutaneous endoscopic technique for the treatment of thoracic OLF accomplished direct decompression of the ossified ligaments with minimal trauma and instability. This technique could be used as an alternative choice. However, the fused types should be performed prudently because of the difficulties of the operation.
经皮内镜下椎间孔入路技术是治疗腰椎间盘突出症甚至腰椎管狭窄症常用的微创手术。本报告描述了经皮内镜技术对胸椎黄韧带骨化（OLF）患者进行的完全减压。
我们对2例因OLF导致胸段脊髓病的患者采用经皮内镜下椎间孔入路手术进行手术减压。术后，患者称术前神经症状有显著改善。术后胸部计算机断层扫描显示韧带骨化已完全清除。
我们应用经皮内镜技术治疗胸椎OLF，以最小的创伤和不稳定性实现了对骨化韧带的直接减压。该技术可作为一种替代选择。然而，由于手术难度，对于融合类型应谨慎操作。
