摘要:

背景:目前常用的椎间融合方法较多,有自体骨块、同种异体骨及钛合金为主的腰椎后路椎间融合器等方法,但各有其优缺点。

目的:观察纳米羟基磷灰石/聚酰胺66复合生物活性椎间融合器用于腰椎后路椎间融合治疗腰椎疾患的临床疗效。

方法:回顾性分析2010年7月至2011年12月赣南医学院第一附属医院骨科收治的行腰椎后路椎间融合患者16例,均置入纳米羟基磷灰石/聚酰胺66复合生物活性椎间融合器。

结果与结论:所有患者随访10-24个月,腰痛均明显减轻,末次随访时腰痛疼痛目测类比评分、腰椎JOA评分及Oswestry功能障碍指数均较治疗前明显改善(P < 0.05)。随访过程中均未发现内固定出现松动、断钉等情况;所有患者末次随访时均获得骨性融合,未见纳米羟基磷灰石/聚酰胺66复合生物活性椎间融合器移位及下沉。表明纳米羟基磷灰石/聚酰胺66复合生物活性椎间融合器用于腰椎后路椎间融合治疗能够重建腰椎稳定性,提供置入后的即刻稳定性,具有良好的生物学性能。

Abstract:

BACKGROUND: There are various commonly used interbody fusion methods, such as autologous bone, allograft bone and titanium-based posterior lumbar interbody fusion, and each method has its own advantages and disadvantages.

OBJECTIVE: To observe the clinical efficacy of a bioactive nano-hydroxyapatite/polyamide 66 fusion cage in posterior lumbar interbody fusion for the treatment of lumbar disease.

METHODS: A retrospective case analysis was conducted on 16 cases treated with posterior lumbar interbody fusion at the Department of Orthopedic, the First Affiliated Hospital of Gannan Medical University from July 2010 to December 2011, and all the patients were implanted with nano-hydroxyapatite/polyamide 66 biological activity fusion cage.

RESULTS AND CONCLUSION: All the patients were followed-up for 10-24 months, and the lumbar pain was significant improved, the lumbar visual analogue score, lumbar Japanese Orthopaedic Association score and Oswestry disability index score were significantly improved during the final follow-up period (P < 0.05). No internal fixation loosing or broken observed in all the patients during final follow-up, and all the patients obtained bone fusion without nano-hydroxyapatite/polyamide 66 fusion cage displacement or subsidence. The results indicate that nano-hydroxyapatite/polyamide 66 fusion cage for the treatment of posterior lumbar interbody fusion can reconstruct the lumbar stability and provide immediate stability after  implantation, and has good biological activity.
