文题释义:
骨小梁钽金属:不仅具备多孔涂层表面,还具有较高的孔隙率,并且材料具有优良的物理、机械特性,更加利于诱导骨的形成,植入机体后能使软组织、液体渗入并牢固附着。钽金属具有稳定的化学性能、良好的耐腐蚀性及熔点高等特点,被广泛应用于航空、军事,并且近十年开始用于临床骨科,作为假体植入、接骨板取得了理想效果。
颈椎病前路减压融合:是一种骨科手术,常见适应证包括:屈曲型颈椎骨折或骨折脱位所致的颈椎创伤性不稳定;颈椎爆裂性骨折,椎体粉碎,压迫脊髓或脊髓前动脉,产生脊髓前综合征,需做前路减压,解除脊髓受压;后路广泛性椎板切除,颈椎不稳,经后外侧融合仍不牢固。
 
摘要
背景:将骨小梁钽金属颈椎间融合器用于前路融合中治疗颈椎病具有重要作用,但目前对其解剖形态颇有争议。
目的:探讨骨小梁钽金属颈椎间融合器在颈椎病患者前路融合手术中的应用效果及解剖形态特征。
方法:纳入颈椎病患者93例,分3组进行颈椎前路减压融合治疗:自体骨组(n=31)进行单纯自体骨植骨融合;聚醚酮组(n=31)进行聚醚酮椎间融合器联合自体骨植骨融合;骨小梁钽金属组(n=31)进行骨小梁钽金属椎间融合器联合自体骨植骨融合。记录3组围手术期并发症;治疗前及治疗后6个月,进行目测类比评分、日本骨科学会评分JOA、颈椎功能障碍指数NDI评估,采用CT观察椎间融合情况、椎间隙高度、融合节段前凸角。
结果与结论:①3组并发症发生率比较无差异;②3组治疗后6个月的目测类比评分、JOA评分、NDI评分均较治疗前明显改善(P < 0.05);治疗后6个月,自体骨组、骨小梁钽金属组JOA评分、NDI评分均较聚醚酮组明显改善(P < 0.05),自体骨组与骨小梁钽金属组JOA评分、NDI评分比较无差异,3组间目测类比评分比较无差异;③3组治疗后6个月的椎间隙高度、融合节段前凸角、融合面积均较治疗前明显改善(P < 0.05);治疗后6个月,自体骨组、骨小梁钽金属组椎间隙高度、融合节段前凸角、融合面积均较聚醚酮组明显改善(P < 0.05),自体骨组与骨小梁钽金属组3项指标比较无差异;④治疗后6个月,骨小梁钽金属组椎间融合率高于自体骨组、聚醚酮组(P < 0.05);⑤结果表明,将骨小梁钽金属颈椎间融合器用于颈椎病前路融合中效果理想,能实现颈椎结构重建,获得较好的稳定性,符合解剖形态学要求。

Abstract:

BACKGROUND: Trabecular tantalum cage plays an important role in anterior cervical discectomy and fusion (ACDF) for cervical spondylosis, but its anatomical morphology remains controversial.

OBJECTIVE: To investigate the effect and anatomical characteristics of trabecular tantalum cage in ACDF for patients with cervical spondylosis.
METHODS: Ninety-three patients with cervical spondylosis were enrolled, and underwent ACDF using bone autograft (n=31, autograft group), polyether ketone cage combined with bone autograft (n=31, polyether ketone group) or trabecular tantalum cage combined with bone autograft (n=31, trial group). The perioperative complications were recorded. Before and 6 months after treatment, the Visual Analogue Scale, Japanese Orthopedic Association, Neck Disability Index, intervertebral fusion, intervertebral space height, and anterior lordosis of fused segment on CT were detected.
RESULTS AND CONCLUSION: (1) There was no difference in the incidence of complication among groups. (2) The Visual Analogue Scale, Japanese Orthopedic Association, and Neck Disability Index scores at 6 months after treatment in each group were significantly improved compared with baseline (P < 0.05). The Japanese Orthopedic Association, and Neck Disability Index scores at 6 months after treatment in the autograft and trial groups were significantly improved compared with the polyether ketone group (P < 0.05), and the scores showed no significant difference between autograft and trial groups. The Visual Analogue Scale scores at 6 months after treatment did not differ significantly among groups. (3) The intervertebral space height, anterior lordosis of fused segment, and fusion area at 6 months after treatment in each group were significantly improved compared with baseline (P < 0.05). The imaging indexes in the autograft and trial groups were significantly improved compared with the polyether ketone group (P < 0.05), but showed insignificant difference between autograft and trial groups. (4) At 6 months after treatment, the fusion rate in the trial group was significantly higher than that in the autograft and polyether ketone groups (P < 0.05). (5) These results imply that trabecular tantalum cage applied in ACDF obtains satisfactory outcomes, and can achieve cervical reconstruction and good stability, which is accordance with the anatomical requirements.
