Zero-p椎间融合器和一体化颈椎钢板融合器治疗脊髓型颈椎病的临床疗效

Clinical efficacy of Zero-p interbody fusion cage and plate cage benezech in treatment of cervical spondylotic myelopathy

目的探讨Zero-p椎间融合器和一体化颈椎钢板融合器(PCB)治疗脊髓型颈椎病的临床疗效。方法将行颈椎前路减压椎间融合术治疗的40例脊髓型颈椎病患者随机分为Zero-p椎间融合器组(A组,20例)和PCB组(B组,20例),比较两组术后临床疗效。结果 A组手术时间和术中出血量均少于B组[(97.7±16.2)min vs.(107.6±12.5)min和(86.5±11.5)ml vs.(93.7±9.1)ml](P<0.05)。与术前相比,两组术后JOA评分、椎间隙高度和Cobb角均增加(P<0.05)。末次随访时,两组患者手术节段均获得骨性融合。A组并发症发生率低于B组(5%vs.35%)(P<0.05)。结论 Zero-p椎间融合器和PCB治疗脊髓型颈椎病均可取得较好的临床疗效,但Zero-p椎间融合器具有操作简便、手术时间少、出血量少和并发症少等优点。

Objective To investigate the clinical efficacy of Zero-p interbody fusion cage and plate cage benezech（PCB） in the treatment of cervical spondylotic myelopathy. Methods A total of 40 patients with cervical spondylotic myelopathy underwent anterior cervical discectomy and fusion was randomly divided into two groups of A（implanted with Zero-p interbody fusion cage, 20 cases） and B （implanted with PCB, 20 cases）. The clinical efficacy after surgery was compared between two groups. Results The operation time and intraoperative blood loss in group A were less than those in group t3[（97.7±16.2） rain vs. （107.6±12.5） min and （86.5±11.5） ml vs. （93.7±9.1） ml] （P〈0.05）. Compared with before, Japanese orthopaedic association （JOA） score, height of intervertebral space and Cobb＇s angle were all increased after surgery （P〈0.05）. The bone graft fusion was achieved at the last time of follow-up in both groups. The incidence of complications in group A was lower than that in group B（5% vs. 35%） （P〈0.05）. Conclusion Both Zero-p interhody fusion cage and PCB achieve good clinical efficacy in the treatment of cervical spondylotic myelopathy, but the former implant has the advantages of easier operation, shorter operation time, tess blood loss and fewer complications.
