This study correlated the relationship between postoperative C6 nerve root palsies and various patient-related clinical, radiographic, and surgical parameters.
The medical records of 318 patients undergoing double-door cervical laminoplasty for myelopathy were reviewed. Twelve (3.8%) had postoperative C6 nerve root palsies. Their clinical, radiographic, and surgical procedures were analyzed looking for a correlation/explanation for these new C6 root deficits.
The following factors correlated with patients' developing new postoperative C6 nerve root deficit following double-door cervical laminoplasty; a high correlation with additional C5 palsies, narrower C6 intervertebral foraminal widths, greater anterior protrusions of the C6 articular process, and larger posterior shifts of the spinal cord on magnetic resonance (MR) between the C4/C5-C6/C7 levels.
Factors correlating with the new onset of C6 nerve root palsies following double-door cervical laminoplasty included; a high correlation with new C5 palsies, more severe foraminal stenosis, greater anterior protrusions of the C6 articular process, and more extensive dorsal spinal cord migration.
本研究关联了术后C6神经根麻痹与各种患者相关的临床、影像学及手术参数之间的关系。
回顾了318例行双开门颈椎椎板成形术治疗脊髓病患者的病历。其中12例（3.8%）出现术后C6神经根麻痹。对他们的临床、影像学及手术过程进行分析，以寻找这些新出现的C6神经根功能缺损的关联因素/解释。
以下因素与双开门颈椎椎板成形术后患者出现新的C6神经根功能缺损相关；与额外的C5麻痹高度相关、C6椎间孔宽度较窄、C6关节突的前凸更大以及在C4/C5 - C6/C7水平之间磁共振成像（MR）上脊髓的向后移位更大。
与双开门颈椎椎板成形术后C6神经根麻痹新发相关的因素包括；与新的C5麻痹高度相关、椎间孔狭窄更严重、C6关节突的前凸更大以及脊髓背侧移位更广泛。
