【摘要】：目的 :分析单节段应用钛笼植骨的颈椎椎体次全切除融合术(anterior cervical corpectomy and fusion,ACCF)术后钛笼下沉的相关危险因素。方法:统计并回顾性分析我院2014年7月~2016年6月间应用钛笼植骨的单节段ACCF的44例患者临床资料,测量术前、术后3d内和术后3个月复查时所拍摄的颈椎X线平片,根据术后3个月随访时融合节段高度与术后3d内融合节段相比高度变化,将患者分为下沉组(高度丢失2mm)与未下沉组(高度丢失≤2mm),测量并分析两组间撑开角、钛笼倾斜角、钛笼深度、钉板夹角之间是否存在统计学差异,并通过Logistic回归分析分析钛笼下沉的危险因素。结果:术后3个月随访时,17例(38.64%)患者纳入未下沉组(高度丢失≤2mm),27例(61.36%)患者纳入下沉组(高度丢失2mm)。下沉组与未下沉组之间钛笼倾斜角、钛笼深度、钉板夹角差异有统计学意义(P0.05),撑开角差异无统计学意义(P0.05)。多因素Logistic回归分析结果提示,钛笼倾斜角增加是钛笼下沉的危险因素[95%置信区间(1.065,1.374),P0.05]。结论:钛笼下沉为ACCF术后常见的现象。钛笼倾斜角为钛笼下沉的独立危险因素,若该角度8.6°将增加钛笼下沉的风险。
[Abstract]:Objective: to analyze the risk factors of titanium cage subsidence after subtotal cervical vertebra resection and fusion with titanium cage graft. Methods: the clinical data of 44 patients with single segmental ACCF treated with titanium cage from July 2014 to June 2016 in our hospital were analyzed retrospectively. The X-ray films taken before operation, within 3 days after operation and 3 months after operation were measured. According to the height change of fusion segment after 3 months follow-up, the patients were divided into two groups: subsidence group (height loss 2 mm) and non-sinking group (height loss 鈮，
