Abstract Percutaneous posterior full-endoscopic cervical foraminotomy and discectomy (PECFD) is recognized as a safe, effective, and minimally invasive treatment for cervical spondylotic radiculopathy (CSR). However, the potential mechanisms of the degenerative changes and postoperative recurrence after PECFD are unclear. In this study, a finite element (FE) analysis and radiological assessment were performed to evaluate the biomechanical effects after PECFD. The FE model indicated that the ROM and IDP of C5–C6 increased significantly after PECFD in the extension loading. The radiological evaluation revealed that the extension ROM of C2–C7 and the operative level increased significantly at the one-year follow-up compared with that obtained preoperatively. Combining the FE results and radiological changes, we conclude that the increase in the ROM and IDP at the operative level in the extension loading is the potential cause of the degenerative changes and recurrences after PECFD surgery.

经皮后路全内窥镜颈椎间孔切开术和椎间盘切除术：有限元分析和放射学评估

摘要 经皮后路全内窥镜颈椎间孔切开术和椎间盘切除术（PECFD）被公认为安全、有效、微创治疗神经根型颈椎病（CSR）。然而，PECFD 后退行性改变和术后复发的潜在机制尚不清楚。在这项研究中，进行了有限元 (FE) 分析和放射学评估，以评估 PECFD 后的生物力学效应。有限元模型表明，在扩展加载中 PECFD 后，C5-C6 的 ROM 和 IDP 显着增加。放射学评估显示，与术前相比，C2-C7 的扩展 ROM 和手术水平在 1 年的随访中显着增加。结合有限元结果和放射学变化，
