The optimal surgical strategy for multilevel cervical spondylotic myelopathy (CSM) has not been defined, and few comparative researches between hybrid decompression and multilevel corpectomy have been conducted. Here, we reported 28 patients of three-level CSM, of whom 12 underwent hybrid decompression and 16 two-level corpectomy, with each type of procedure chosen according to radiologic characteristics of those patients. Clinical and radiologic parameters of both groups showed various degrees of improvement. However, no statistically significant differences in Japanese Orthopedic Association (JOA) score improvement rate, graft fusion rate, post-operative neck disability index (NDI) or segmental lordosis between the two groups were found. We conclude that both hybrid decompression and two-level corpectomy could obtain satisfying clinical efficacy in the management of three-level CSM for appropriate patients.
多节段脊髓型颈椎病(CSM)的最佳手术策略尚未明确,且关于混合减压术与多节段椎体次全切除术之间的比较研究较少。在此,我们报告了28例三节段CSM患者,其中12例行混合减压术,16例行两节段椎体次全切除术,每种手术方式均根据患者的影像学特征选择。两组的临床和影像学参数均有不同程度改善。然而,两组之间在日本骨科协会(JOA)评分改善率、植骨融合率、术后颈部功能障碍指数(NDI)或节段性前凸方面未发现统计学上的显著差异。我们得出结论,对于合适的患者,混合减压术和两节段椎体次全切除术在治疗三节段CSM时均可获得满意的临床疗效。
