文题释义:
植骨术:是用手术方法将骨组织移植到患者体内骨缺损、需要加强或融合的部位。由于骨来源不同,分为自体骨移植及同种骨移植,随着冷藏设备和无菌防腐技术的进步,现在用骨库储存同种骨。常用范围有骨质缺损、骨折不愈合、填充囊性病灶或良性肿瘤刮除后所遗留的空腔、脊椎及关节融合等。自体骨移植可取自胫骨前内侧面中部,腓骨上段、髂翼、肋骨以及离断肢体远端之健康骨。
零切迹颈椎前路椎间融合器:具有融合器本体,融合器本体包括位于前部的融合部分与位于后部的锁定部分,融合器本体由PEEK材料一体制成,融合部分的表面设置凸起,锁定部分开设有4个纵向方向贯穿并倾斜的螺纹孔,其中位于中间的螺纹孔的倾斜方向与其两侧的螺纹孔的倾斜方向相反。融合器本体与锁定螺钉配合使用,由锁定螺钉直接将融合器本体与骨固定。
 
摘要
背景:颈椎前路减压植骨融合内固定治疗多节段脊髓型颈椎病在临床上已得到广泛应用,然而术后并发症较多。
目的:比较零切迹融合器与颈椎前路减压植骨融合应用于多节段脊髓型颈椎病治疗效果。
方法:71例多节段脊髓型颈椎病患者随机分成2组,分别为前路减压零切迹融合器植入组、及前路减压钛板联合cage固定组,采用脊髓功能JOA评分,融合率,吞咽困难、食管漏发生率等指标对比2组疗效。
结果与结论:①内固定后随访3-34个月,平均17.5个月。末次随访两组患者脊髓功能恢复优良率差异无显著性意义;②2组最终融合率无差别,但6个月及9个月时零切迹融合器植入组融合率高于钛板联合CAGE固定组(P < 0.05);③零切迹融合器植入组术后吞咽困难发生率3%(轻度1例),钛板联合CAGE固定组29%(轻度3例,中度5例,重度2例),差异有显著性意义(P < 0.05);零切迹融合器植入组无内固定松动、移位发生,而钛板联合CAGE固定组可见1例螺钉松动,2例融合器向后移位的情况发生;零切迹融合器植入组出血量、手术时间及术中透视次数均低于钛板联合CAGE固定组(P < 0.05);④结果提示,颈椎前路减压零切迹融合器植入与传统减压植骨融合治疗多节段脊髓型颈椎病相比,在促进脊髓功能恢复方面及最终融合率无显著差异,但术后内固定稳定性好,中期融合率高,术后吞咽困难发生率低。

Abstract:

BACKGROUND: Anterior cervical decompression and fusion has been widely used in the treatment of multi-level

cervical spondylotic myelopathy, but accompanied with lots of complications.
OBJECTIVE: To investigate the efficacy of zero-profile interboby fixation system for multi-level cervical spondylotic myelopathy.
METHODS: Seventy-one patients with multi-level cervical spondylotic myelopathy were randomly divided into two groups, and the patients in group A accepted zero-profile interboby fixation system, and group B accepted cage interboby fixation system. The Japanese Orthopaedic Association score, fusion rate, as well as the incidence of dysphagia and esophageal fistula were detected to compare the efficacy between two groups.
RESULTS AND CONCLUSION: (1) All cases were followed-up for 3-34 months, average of 17.5 months. The excellent and good rate at the last follow-up showed no significant difference between two groups. (2) The final fusion rate did not differ significantly between two groups, but the fusion rate in the group A was significantly higher than that in the group B at 6 and 9 months postoperatively (P < 0.05). (3) There was one patient with mild dysphagia in the group A (3%), three mild, five medium, and two severe dysphagia in the group B (29%), which showed significant difference between two groups (P < 0.05). No internal fixation loosening occurred in the group A, but three cases in the group B. The blood loss, operation time and radiology times in the group A were significantly lower than those in the group B (P < 0.05). (4) These results suggest that the effect of these two surgical methods in promoting functional recovery of spinal cord and final fusion rate show no significant differences; however, the zero-profile interboby fixation system exhibits better postoperative stability and interim fusion rate, with lower incidence of dysphagia.
