研究设计：对采用独立聚醚醚酮（PEEK）融合器进行两节段颈椎前路椎间盘切除融合术（ACDF）治疗脊髓型颈椎病（CSM）的患者进行回顾性评价。目的：评估独立聚醚醚酮融合器在两节段颈椎椎间融合术治疗脊髓型颈椎病（CSM）中的疗效。文献概述：ACDF是治疗退行性椎间盘疾病的标准手术程序。然而，对于 2 节段 ACDF 使用额外的前路钢板仍然存在争议。方法：我们回顾了 7 年期间（2007-2015 年）在一家地区医院接受带有独立 PEEK 笼的 2 节段 ACDF 进行 CSM 的患者的结果。对日本骨科协会 (JOA) 评分、融合率、下沉率、融合器移位、颈椎 C2-7 角对齐以及颈椎局部节段角 (LSA) 进行了评估。结果：2007 年至 2015 年间，共有 31 名患者（平均年龄，59 岁；范围，36-87 岁）接受了仅融合器构建手术的 2 级 ACDF。最小随访时间为 24月；平均随访时间为 51 个月。 45%进行了C3-5融合，32%进行了C4-6融合，23%进行了C5-7融合。平均 JOA 评分从 10.1 +/- 2.2 提高到 13.9 +/- 2.1 (p
Study Design: A retrospective review of patients who underwent 2-level anterior cervical discectomy and fusion (ACDF) with stand-alone polyetheretherketone (PEEK) cages for cervical spondylotic myelopathy (CSM).Purpose: To evaluate the efficacy of stand-alone PEEK cage in 2-level cervical interbody fusion for CSM.Overview of Literature: ACDF is a standard surgical procedure to treat degenerative disc disease. However, the use of additional anterior plating for 2-level ACDF remains controversial.Methods: We reviewed outcomes of patients who underwent 2-level ACDF with stand-alone PEEK cages for CSM over a 7-year period (2007-2015) in a regional hospital. Japanese Orthopaedic Association (JOA) score, fusion rate, subsidence rate, cage migration, and cervical alignment by the C2-7 angle as well as the local segmental angle (LSA) of the cervical spine were assessed.Results: In total, 31 patients (mean age, 59 years; range, 36-87 years) underwent 2-level ACDF with a cage-only construct procedure between 2007 and 2015. The minimum follow-up was 24 months; mean follow-up was 51 months. C3-5 fusion was performed in 45%, C4-6 fusion in 32%, and C5-7 fusion in 23%. Mean JOA score improved from 10.1 +/- 2.2 to 13.9 +/- 2.1 (p
