文题释义:
腰椎间盘突出并椎管狭窄症:是腰椎间盘突出症和腰椎椎管狭窄症两种疾病合并发生产生一系列腰腿痛和间歇性跛行等症状为临床表现的疾患。
退变性腰椎滑脱症:是指因腰椎退变使节段性不稳加重,椎间隙狭窄、小关节退变增生及半脱位,上下小关节间角改变,而导致椎体滑脱。
 
摘要
背景:有研究表明骶骨倾斜角的丢失可能是下腰痛的重要解剖基础之一,腰椎融合术后骶骨倾斜角发生相应变化,其在缓解腰痛方面的临床意义尚需明确。
目的:分析L4-5后路椎体间融合后早期骶骨倾斜角变化及其临床意义。
方法:纳入L4-5腰椎间盘突出并椎管狭窄症和L4滑脱症经后路椎间盘摘除、椎间植骨、椎弓根钉内固定后的患者共60例,L4-5椎间盘突出并椎管狭窄症38例设为腰椎管狭窄症组,L4滑脱症22例设为腰椎滑脱症组。随访时间12-24个月,对比术前与术后随访时的骶骨倾斜角变化。根据手术后疗效按MacNab分类分为疗效佳(优)与欠佳(良、中、差),比较分析术后疗效与年龄、性别、骶骨倾斜角变化的相关性。
结果与结论:术后12-24个月,腰椎管狭窄症组与腰椎滑脱症组患者骶骨倾斜角均较术前增大(P < 0.05),而两组之间骶骨倾斜角变化的差异无显著性意义(P > 0.05)。年龄、性别及骶骨倾斜角变化对术后早期疗效的差异无显著性意义,且无相关性(P > 0.05)。提示:后路椎间盘摘除、椎间植骨、椎弓根钉内固定术后早期可显著改善腰椎管狭窄症与腰椎滑脱症患者骶骨倾斜角;年龄、性别及骶骨倾斜角变化不是影响术后早期疗效的相关因素。

Abstract:

BACKGROUND: Loss of sacral slope has been shown to be an important anatomic basis for low back pain. The effect of sacral slope changes after lumbar fusion on pain relief remains unclear.

OBJECTIVE: To analyze the variations of sacral slope and clinical significance at the early stage after posterior lumbar interbody fusion at L4-5.
METHODS: Sixty patients with herniation at disc levels L4-5 and spinal stenosis (n=38) or lumbar spondylolisthesis at L4 (n=22) undergoing posterior lumbar interbody fusion were enrolled. All patients were followed up for 12-24 months to compare the sacral slop at baseline and postoperatively. The clinical outcomes were evaluated by MacNab criteria, and its correlation with age, sex and sacral slop variations was analyzed.
RESULTS AND CONCLUSION: At 12-24 months postoperatively, the sacral slope in the two groups was significantly improved than that at baseline (P < 0.05), but there was no significant difference in sacral slop between two groups (P > 0.05). The age, sex and sacral slop variations showed no significant effects on the early clinical outcomes (P > 0.05). These results suggest that posterior lumbar interbody fusion can markedly improve the sacral slope in patients with spinal stenosis and lumbar spondylolisthesis at early period. Furthermore, age, sex, and sacral slope variations all show no obvious effect on postoperative early functional recovery.
