摘要
目的探讨颈前路椎体切除植骨融合术后钛网沉陷的风险因素以及钛网沉陷对临床疗效的影响。方法 2003年5月~2007年8月采用颈前路椎体切除植骨融合术治疗颈椎疾病患者300例。分析患者的年龄、性别、切除节段、固定钢板的类型以及是否使用垫片这5个因素是否为钛网沉陷的风险因素,研究钛网沉陷对颈椎曲度及其他临床疗效的影响。结果随访1年,239例(79.7%)患者发生钛网沉陷,其中182例(60.7%)发生轻度沉陷(1~3mm),57例(19.0%)发生严重沉陷(>3mm)。双节段切除较单节段切除更易发生严重钛网沉陷。发生严重钛网沉陷的患者术后神经功能恢复率明显低于未发生钛网沉陷的患者。同时,钛网严重沉陷增加了患者颈肩部疼痛、神经症状复发以及内固定失败的发生率。结论钛网沉陷在颈前路椎体切除钛网植骨融合术后发生较为普遍。多节段切除是发生严重钛网沉陷的危险因素,严重钛网沉陷可导致手术疗效下降及相关并发症的发生。
