摘要 目的利用X线平片确定颈椎融合术后相邻节段骨化发展和成熟的时间,研究颈椎前路钛板<椎体高度1/2和≥椎体高度1/2的患者骨化发展的不同。方法对42例患者的77个椎间盘,用术后颈椎侧位X线片测量钛板和椎体高度,将相邻椎间盘分为钛板<椎体高度1/2组和钛板≥椎体高度1/2组。在术后的第3,6,12,24个月,每年1次评价骨化的表现和严重性,记录分成4级,分析0级或1级骨化的椎间盘是否在24个月或者剩下的随访时间(平均45个月)进展为晚期(2级或3级)骨化。结果与钛板<椎体高度1/2的节段相比(50%,11/22),钛板≥椎体高度1/2的节段骨化发生率(86%,47/55)明显提高。15个进展为晚期骨化病例中,13例(86.7%)的钛板≥椎体高度1/2。结论利用颈椎侧位X线片可以评价颈椎术后相邻节段骨化情况。钛板≥椎体高度1/2患者比钛板和钛板小于椎体高度1/2患者的相邻节段更容易发生骨化。
