【摘要】：目的回顾性分析腰椎退行性疾病行融合术后相应节段椎体硬化和前缘骨赘的变化。方法将30例患者共60个椎体纳入研究,其中男性9例,女性21例;年龄45~86岁,平均(66.8±11.2)岁。根据术式将患者分为后外侧融合术(posterolateral fusion,PLF)组和后路椎间融合术(posterior lumbar interbody fusion,PLIF)组,其中PLF组14例,共28个椎体;PLIF组16例,共32个椎体。分别在术前及术后第3、6、12、24个月和末次随访时拍摄腰椎侧位片,测量各时间点受累节段上下椎体的硬化区面积和骨赘长度。结果腰椎融合术后对应的硬化区面积和骨赘长度随着时间逐渐减小,这种改变在术后3个月时即可观察到,而在0~3个月和3~6个月随访区间内减少幅度最显著;在PLF组和PLIF组内骨硬化和骨赘的变化情况相似。结论腰椎融合术后可观察到椎体硬化区和前缘骨赘的吸收,而且最显著的吸收发生在术后3个月和6个月内。
[Abstract]:Objective to retrospectively analyze the changes of anterior osteophyte and segmental sclerosis after lumbar fusion for lumbar degenerative diseases. Methods A total of 60 vertebrae were included in the study, including 9 males and 21 females, aged 45 to 86 years, with an average age of 66.8 卤11.2 years. According to the operation method, the patients were divided into two groups: posterior lumbar interbody fusion group (PLF group, n = 14) and posterior intervertebral fusion group (PLF group, n = 16). Lumbar lateral radiographs were taken before operation and at the 3rd postoperatively at 12,24 months and at the last follow-up. The sclerosing area and osteophyte length of the upper and lower vertebrae were measured at each time point. Results the area of sclerosing area and the length of osteophyte decreased gradually with time after lumbar fusion. The changes were observed at 3 months after operation, and the decrease was most significant in the follow-up interval of 0 ~ 3 months and 3 ~ 6 months. The changes of bone sclerosis and osteophyte in PLF group and PLIF group were similar. Conclusion the absorption of osteophytes in the sclerosing area and anterior edge of the vertebral body can be observed after lumbar fusion, and the most significant absorption occurs within 3 and 6 months after operation.
