研究目的:

1.通过前瞻性随机对照研究分析 3D 打印钛金骨小梁人工椎体治疗颈椎 OPLL 患者术前、术后不同随访时间的 JOA 评分,影像学检查评估融合及植入物沉降情况及并发症等,明确 3D 打印人工椎体置入治疗颈椎 OPLL 的疗效; 2.通过比较 3D 打印钛金骨小梁人工椎体与钛笼植骨置入治疗颈椎 OPLL 疗效与安全性对比,明确 3D 打印钛金骨小梁人工椎体治疗颈椎 OPLL 的优势,为以后的临床应用与相关技术革新和升级打下基础并提供参考。  

Objectives of Study:

1. A prospective randomized controlled study was conducted to analyze the JOA scores of 3D printed titanium trabecular bone artificial vertebral body for cervical OPLL patients before and after operation at different follow-up times, and imaging examinations to evaluate fusion and implant settlement and complications, etc. , to clarify the efficacy of 3D printed artificial vertebral body implantation in the treatment of cervical OPLL; 2. By comparing the efficacy and safety of 3D printed titanium trabecular artificial vertebral body and titanium cage bone grafting in the treatment of cervical OPLL, the advantages of 3D printing titanium trabecular artificial vertebral body in the treatment of cervical OPLL are clarified, which can be used for future research. Clinical applications and related technological innovations and upgrades lay the foundation and provide references.
