Abstract
The aim of this research is to explore the difference of imaging parameters in patients with C5 palsy after cervical expansive open-door laminoplasty. A retrospective analysis was made on the clinical data of 62 patients who were diagnosed as multiple cervical spondylotic myelopathy and operated with cervical expansive open-door laminoplasty using Centerpiece titanium miniplate fixation. According to weather C5 nerve root palsy occurred after surgery, the patients were divided into normal group (group A with 8 cases) and paralysis group (group B with 54 cases). The preoperative and postoperative cervical spine angle (C2–7) enlargement rate of spinal canal, distance of spine cord shifting and cervical curvature between two groups were measured. Compare with group A (27.38±1.99°), the average lamina open angle of group B (34.56±5.55°) was larger, which were found statistically significant difference (P<0.05). In addition, there were no significant differences between two groups in C3 or C7 lamina open angle. However, significant differences were found between two groups in C4, C5 and C6 lamina open angle. The average enlargement rate of spinal canal and distance of spine cord shifting of group B were larger than group A, which was statistically differences (P<0.05). The opening angle of the lamina, the expansion rate of the spinal canal, and the distance of the spinal cord may prevent the occurrence of cervical 5 nerve root palsy in cervical expansive open-door laminoplasty.
