摘要
目的观察腰椎退行性疾病手术病人术前邻近节段椎间盘的退变情况及分布规律。方法回顾性分析济南军区总医院2012年1月至2016年2月收治的503例行手术治疗腰椎退行性疾病病人的术前临床资料,其中男240例(47.71%),女263例(52.29%);年龄为20~84岁,平均48.8岁。腰椎间盘突出症352例,退变性腰椎滑脱症91例,退变性腰椎管狭窄症60例。通过术前X线片评估腰椎稳定性;基于术前MRI,采用Pfirrmann分级标准评价腰椎间盘退变程度,记录Modic改变、高信号区域及许莫氏结节的发生情况。结果 503例中仅5例为单节段退变,12例为跳跃节段退变,余486例均为多节段退变。共1 863个(1 863/2 515,74.08%)腰椎间盘发生退变,5个节段椎间盘(L1~2、L2~3、L3~4、L4~5、L5~S1)均退变的病人比例为39.56%(199例)。不稳定节段数为127个,Modic改变为188个,高信号区域为241个,许莫氏结节节段数为161个。30岁以下男性病人腰椎间盘退变率较女性高;随着年龄增长,女性病人椎间盘退变率增加,退变程度加重。腰椎不稳、Modic改变、高信号区和许莫氏结节均与椎间盘退变存在明显相关性(P均<0.05)。某一腰椎节段(L3~4、L4~5、L5~S1)椎间盘发生PfirrmannⅣ、Ⅴ级退变时,邻近节段椎间盘退变(PfirrmannⅢ+Ⅳ+Ⅴ级)比例均超过了80%,且严重退变(PfirrmannⅣ+Ⅴ级)比例也较高,超过60%。结论术前邻近节段椎间盘退变广泛存在,在临床工作中要予以重视。
