【摘要】：目的：分析经颈前路椎体次全切除术(ACCF)治疗的脊髓型颈椎病术后钛笼下沉的相关影响因素。方法：回顾我科于2011年1月至2013年4月收治的,86例行颈椎前路椎体次全切除减压+钛笼植骨融合+钛板内固定术患者的资料,取术后随访6个月时的影像学资料,根据颈椎侧位片显示钛笼下沉与否,分下沉组和非下沉组进行观察,分析术后钛笼下沉与年龄、性别、BMI值、手术节段、临床疗效、病变节段撑开角度和安置位置的关系。结果：①单因素分析结果：年龄、性别、BMI值、手术节段(C5-C7)这几个方面的比较,差异有统计学意义(P0.05),其余差异无统计学意义(P0.05)。两组术后JOA评分均较术前明显改善,差异有统计学意义(P0.05),两组间比较存在显著统计学差异(P0.01)。两组融合率比较无明显统计学差异(P0.05)。撑开角度30°者共63例,下沉组12例(19.0%),撑开角度≥30°者共23例,下沉组10例(43.5%)。撑开角度30°与撑开角度≥30°对于下沉发生率的影响比较有统计学差异(P0.05)。椎体前缘与钛笼前缘间距lmm者共66例,下沉组13例(19.7%),椎体前缘与钛笼前缘间距≥1mm者共20例,下沉9例(45.0%),间距≥1mm与间距1mm对术后钛笼下沉发生率的影响,其差异有统计学意义(P0.05)。②多因素分析结果显示：撑开角度(OR=6.236,P=0.005)和安置位置(OR=4.583,P=0.024)可能是ACCF术后钛笼下沉的危险因素。结论：撑开角度和安置位置可能是影响术后引起钛笼下沉的重要因素,此外年龄、性别、手术节段(C5-C7)、BMI对钛笼下沉均有不同程度的影响。
[Abstract]:Objective: to analyze the related factors of titanium cage sinking in cervical Spondylotic myelopathy treated by subtotal cervical vertebra resection (ACCF) via anterior cervical approach. Methods: from January 2011 to April 2013, 86 patients with anterior subtotal cervical vertebra resection, decompression, titanium cage, bone fusion and titanium plate fixation were retrospectively reviewed. The imaging data of the patients who were followed up for 6 months after operation were analyzed. According to the lateral radiographs of cervical vertebrae, titanium cage sinking was observed, and the relationship between titanium cage subsidence and age, sex, BMI value, operative segment, clinical effect, the angle of extension of lesion segment and placement position was analyzed. Results: 1 the results of univariate analysis: age, sex, BMI value, operative segment (C5-C7), the differences were statistically significant (P0.05), the other differences were not statistically significant (P0.05). The postoperative JOA scores of the two groups were significantly improved compared with the preoperative, the difference was statistically significant (P0.05), there was a significant difference between the two groups (P0.01). There was no significant difference in fusion rate between the two groups (P0.05). There were 63 cases of distraction angle 30 掳, 12 cases (19.0%) of sinking group, 23 cases of distraction angle 鈮，
