摘要:

背景:近几年来国内各大医院广泛采用Coflex治疗腰椎间盘突出症及腰椎管狭窄症,并取得了良好的治疗效果。
目的:探讨Coflex棘突间动态稳定装置治疗腰椎退变性疾病的疗效,并通过随访治疗后椎间孔高度的变化及内固定后腰椎功能恢复情况来探讨椎间孔撑开高度与临床疗效之间的关系。
方法:行Coflex植入内固定治疗腰椎间盘突出及腰椎管狭窄症的病例,随访患者的椎间孔的高度、椎体前缘及后缘高度。记录患者内固定治疗前、治疗后1年及末次随访时的ODI及目测类比评分值。
结果与结论:内固定治疗后患者的椎间隙前缘高度、椎间隙后缘高度及椎间孔高度较内固定前均有明显的增高,治疗后1周内复查的X射线平片显示椎间孔及椎间隙高度达到最大值,此后随着随访时间的延长,各高度均随着时间的延长而不同程度的下降。在平均内固定后26.4个月随访时的椎间隙高度及椎间孔高度较内固定前的高度仍具有显著差异。根据ODI功能评分及目测类比评分疼痛评分结果,治疗后3个月即可见患者功能明显改善,在内固定后1年左右进一步改善,腰椎功能恢复效果达到最佳,末次随访时ODI评分值与内固定后1年随访值的差异无显著性意义。说明Coflex治疗腰椎间盘突出症及轻中度腰椎管狭窄症可取的较为理想的治疗效果,其治疗的效果主要来自于术中对硬膜及神经根的减压,而Coflex对椎间孔高度的恢复随着随访时间的延长会逐渐丢失。

Abstract:

BACKGROUND: Recently, Coflex was widely used in hospital in China for the treatment of lumbar disc herniation and lumbar spinal stenosis, and obtained perfect therapeutic effects.
OBJECTIVE: To discuss the curative effect of treating lumbar degenerative diseases by Coflex interspinal device, and to explore the relationship between foraminal height and the curative effect by comparing the change of foraminal height and the change of lumbar function.
METHODS: Coflex implantation for lumbar disc herniation and lumbar spinal stenosis was performed. The foraminal height and the heights of anterior and posterior borders were investigated. ODI and visual analogue scale before internal fixation, at 1 year after treatment and during follow-up were recorded.
RESULTS AND CONCLUSION: The foraminal height and the heights of anterior and posterior borders were obviously increased after internal fixation. At 1 week after treatment, radiographs exhibited that the foraminal height and intervetebral height were maximal. The foraminal height and the heights of anterior and posterior borders decreased with prolonged follow-up time. At 26.4 months after mean internal fixation, significant 
differences in the foraminal height and intervetebral height were detected as compared with pre-fixation. Results of ODI and visual analogue scale demonstrated that patients’ functions were significantly improved at 3 months after treatment, and further improved at about 1 year after fixation. The recovery of lumbar vertebra function was optimal. No significant difference in ODI score was detectable between final follow-up and 1-year fixation. These results suggested that Coflex for lumbar disc herniation and mild and moderate lumbar spinal stenosis obtained ideal therapeutic effects. Its therapeutic effects mainly originate from the intraoperative decompression on dura mater and nerve root. However, Coflex effects on the recovery of foraminal height gradually lost with prolonged follow-up time.
