SOLIS在颈椎前路融合术中的应用

目的 探讨新型颈椎前路融合器(SOLIS)在颈椎前路融合术中的应用效果.方法 对18例脊髓型颈椎病、12例颈椎间盘突出症采用颈椎前路减压融合术,小切口入路(3～4 cm),椎间盘及部分椎体后缘切除后保留椎体终板,植人带自体松质骨的SOLIS.以手术前后X线片及JOA评分评价疗效.结果 30例随访6～18个月,平均12.5个月.置人的SOLIS位置良好,无移动及脱出迹象;病变椎间隙高度恢复正常,未见椎间高度丢失;所有节段均于术后3～8个月骨性融合.术前JOA评分平均10.4分,术后平均14.9分,两者有统计学意义(P＜0.01).结论 颈椎前路融合器SOLIS具有良好的生物相容性,手术创伤小,能有效地恢复颈椎高度,融合率高,融合后稳定性好,神经功能改善优良率高.

Application of SOLIS in Anterior Cervical Intervertebral Fusion

Objective To investigate the application of SOLIS in the anterior intervertebral fusion.Methods The operations and results of the surgery of anterior intervertebral fusion in 18 patients with cervical spondylotic myelopathy and 12 patients with cervical intervertebral disc herniation were reviewed.SOLIS filled with autogenous cancellous bone was implanted between the cervical vertebrae and the endplate were preserved after the cervical intervertebral disc and some parts of the posterior border of the vertebral body were removed.Every patient had a short neck incision.Recovery of nerve function was evaluated by JOA score and the fusion state,stability and changes of intervertebra height of fusion segment were evaluated by X-ray.Results The migration of the implanted SOLIS cage was not found in follow-up ranging from 6 to 18 months,with an average of 12.5 months.The height of the involved cervical intervertebral spaces was restored and loss of height of intervertebral did not occur.Bony fusion could be found 3 to 8 months after operation.The average JOA was 10.4 preoperatively and 14.9 postoperatively with significant difference(P<0.01).Conclusion SOLIS with excellent biocompatibility and fewer invasions can restore and maintain the intervertebral disc height effectively with satisfactory fusion rate.The patients can recover quickly after SOLIS is used in anterior intervertebral fusion and have excellent results in short term.
