Surgical management of degenerative cervical myelopathy requires careful pathoanatomic consideration to select between various surgical options from both anterior and posterior approach. Hitherto, unexplored is the relevance of cervical deformity to the pathophysiology of such neurological disability, and whether correction of that deformity should be a surgical objective when planning for reconstruction after spinal cord decompression. Such correction could address both the static cord compression and the dynamic repetitive cord injury, while also restoring more normal biomechanics to the cervical spine. The articles in this focus issue's section on cervical spinal deformity reveal that cervical sagittal alignment is geometrically related to thoracolumbar spinal pelvic alignment and to T1 slope, and that it is further clinically correlated to regional disability and general health scores and to myelopathy severity. These conclusions are based on narrative reviews and a selection of primary research data, reflecting the nascency of this field. They further recommend for preoperative assessment of spinal alignment when significant deformity is suspected, and that correction of cervical kyphosis should be an objective when surgery is planned.
退行性颈脊髓病的手术治疗需要仔细的病理解剖学考虑,以便在前后入路的各种手术方案中进行选择。迄今为止,颈椎畸形与这种神经功能障碍的病理生理学的相关性,以及在脊髓减压后重建时是否应将畸形矫正作为手术目标,这些问题仍未得到探索。这种矫正既可以解决脊髓的静态压迫,也可以解决脊髓的动态反复损伤,同时还可以使颈椎的生物力学恢复到更正常的状态。本专题关于颈椎脊柱畸形部分的文章表明,颈椎矢状位排列与胸腰椎骨盆排列和 T1 斜率在几何上相关,并且与区域性残疾和总体健康评分以及脊髓病严重程度进一步相关。这些结论基于叙述性综述和部分原始研究数据,反映了该领域的新生。他们进一步建议,当怀疑存在明显畸形时,应在术前评估脊柱排列情况,如果计划手术,则应将颈椎后凸的矫正作为目标。
