Purpose

This study aims to assess whether computer navigation can improve the accuracy of the trough position and clinical outcomes of expansive open-door cervical laminoplasty (EOLP).

Methods

We reviewed a single centre of 28 conventional EOLP and 24 computer navigation EOLP cases. The conventional group had 102 laminae while the navigation group had 88. The distance from the medial cortex to the pedicle on the open-door side (OD) and hinge side (HD) was measured. Furthermore, the area of the spinal canal corresponding to each lamina before and after the surgical procedure was also measured. We then compared the differences in radiographic parameters and clinical outcomes between the two groups.

Results

OD and HD were smaller in the navigation group compared to the conventional group, and the enlarged area of the spinal canal was larger in the navigation group than in the conventional group. The Japanese Orthopaedic Association (JOA) scores one year after the surgical procedure improved in both groups compared to the pre-operative period, and the JOA recovery rate was higher in the navigation group. The incidence of hinge fracture was lower in the navigation group, and the incidence of C5 palsy and axial pain was not statistically different between the two groups.

Conclusion

The use of computer navigation techniques has the potential to significantly improve the accuracy of EOLP compared to conventional procedures. It has been shown to more fully expand the spinal canal and contribute to clinical efficacy.

使用计算机导航技术的扩大开门颈椎椎板成形术中谷位置的准确性：一项单中心回顾性研究

目的

本研究旨在评估计算机导航是否可以提高扩大开门宫颈椎板成形术 (EOLP) 的槽位准确性和临床结果。

方法

我们审查了一个中心的 28 个常规 EOLP 和 24 个计算机导航 EOLP 案例。常规组有 102 个椎板，而导航组有 88 个。测量开门侧 (OD) 和铰链侧 (HD) 从内侧皮质到椎弓根的距离。此外，还测量了手术前后对应于每个椎板的椎管面积。然后我们比较了两组之间放射学参数和临床结果的差异。
