摘要

目的

探讨3D打印椎间融合器应用于颈椎前路减压植骨融合术治疗脊髓型颈椎病的临床效果。

方法

选取2020年6月至2023年6月在我院采用颈椎前路融合术治疗的100例脊髓型颈椎病患者作为研究对象，按照随机数字表法分为3D组和对照组，每组50例。3D组患者采用3D打印的微孔金属材料椎间融合器，对照组患者采用聚醚醚酮材料的椎间融合器。比较2组患者手术相关指标、颈椎影像学参数、颈部脊髓功能、颈椎轴性功能及手术并发症情况。

结果

2组患者的手术时间、术中出血量及住院时间比较，差异均无统计学意义（

0.05）。2组患者术后各时间点的颈椎融合节段高度、融合节段Cobb角均较术前显著增加（

0.05）；3D组患者术后1、3、6个月的颈椎融合节段高度、融合节段Cobb角均大于对照组（

0.05）。3D组患者术后6个月的主观症状评分、日本骨科协会（JOA）总分均高于对照组（

0.05）。3D组患者术后6个月的颈椎轴性功能优于对照组（

0.05）。3D组患者手术并发症发生率低于对照组（

0.05）。

结论

颈椎前路减压植骨融合术治疗脊髓型颈椎病患者术中使用3D打印椎间融合器植入方案可明显改善患者的临床症状，获得更好的颈椎轴性功能，且并发症少。

Abstract

Objective

To explore the clinical effect of 3D-printed interbody fusion cage applied in anterior cervical decompression and bone graft fusion for the treatment of cervical spondylotic myelopathy.

Methods

A total of 100 patients with cervical spondylotic myelopathy who underwent anterior cervical fusion surgery in our hospital from June 2020 to June 2023 were selected as the research subjects，they were randomly divided into the 3D group and the control group according to the random number table method，with 50 cases in each group.Patients in the 3D group were implanted with a 3D-printed interbody fusion cage which was made of microporous metal materials， while patients in the control group were implanted with intervertebral fusion cage which was made of polyetheretherketone material. The surgery-related indicators， cervical imaging parameters， cervical spinal cord function， cervical axial function and surgical complications of patients between the two groups were compared.

Results

There was no statistically significant difference in the operation time， intraoperative blood loss or length of hospital stay of patients between the two groups （

0.05）. The height of the cervical fusion segments and the C

obb angle of the fusion segments of patients in both groups at each time point after the operation were significantly increased compared with those before the operation （

0.05）. The height of the cervical fusion segments and the Cobb angle of the fusion segments of patients 1 month， 3 months， and 6 months after the operation in the 3D group were all greater than those in the control group （

0.05）. The subjective symptom score and the total score of the Japanese orthopaedic association （JOA） of patients 6 months after the operation in the 3D group were higher than those in the control group （

0.05）. The cervical axial function of patients 6 months after the operation in the 3D group was better than that in the control group （

0.05）. The incidence of surgical complications in the 3D group was lower than that in the control group （

0.05）.

Conclusion

The use of 3D-printed interbody fusion cage during the anterior cervical decompression and bone graft fusion for patients with cervical spondylotic myelopathy can significantly improve the clinical symptoms of patients， achieve better cervical axial function， and have fewer complications.
