文题释义:
腰椎后路椎体间融合:通过直接去除病变椎间盘及周围增生组织对神经根及硬膜囊的压迫而缓解症状,通过置入椎弓根螺钉重建腰椎手术节段的初始稳定性,通过椎间隙植入融合器或植骨块与上下椎体形成骨性连接而重建腰椎的前中柱,保证手术的中远期疗效。
腰椎退变:其实质是关节软骨发生退变,继发以关节边缘和软骨下骨质以增殖性新形成的一种关节病变。
 
摘要
背景:腰椎后路椎体间融合是腰骶椎退变性疾病常规有效的治疗方法之一。目前,大部分学者对置入椎间隙的融合器进行加压固定,预防其移位。而另一部分学者认为不加压有利于增加椎间隙及椎间孔高度,提高临床疗效,且不会增加融合器移位的风险。
目的:比较加压与不加压固定融合器对腰椎后路椎体间融合疗效的影响。
方法:回顾性分析2009年8月至2014年6月采用腰椎后路椎体间融合治疗的64例单节段腰椎退变患者,根据是否通过椎间隙加压固定融合器,分为加压组30例与不加压组34例。
结果与结论:①疗效:每组术后腰、腿痛目测类比评分,Oswestry功能障碍指数、SF-36评分、椎间隙高度、椎间孔高度及腰椎前凸角均较术前明显改善(P < 0.05),不加压组椎间隙、椎间孔高度及腰椎前凸角明显优于加压组(P < 0.05);②腰椎融合率:术后6,12个月及末次随访时的融合率比较差异均无显著性意义(P > 0.05);③相关性分析:两组椎间隙及椎间孔高度的增加与临床疗效的改善均无显著相关性(P > 0.05);④试验结果显示,加压与不加压固定融合器治疗腰骶椎退变性疾病的临床疗效相当,不加压有利于增加椎间隙及椎间孔高度,而两者均有利于恢复腰椎生理前凸,但与临床疗效的提高并无相关性。

Abstract:

BACKGROUND: The posterior lumbar interbody fusion is one of the effective methods for the treatment of lumbar and sacral spine diseases. Most surgeons fix the cage by compressing the disc space in order to keep stability and prevent dislodgement. However, some surgeons think that the non-compression technique does favor for increasing of the disc and foraminal height and thus improving the clinical outcomes, and does not increase the risk of fusion shift.

OBJECTIVE: To compare the effects in fixing the cage by the compression and non-compression techniques on posterior lumbar interbody fusion. 
METHODS: Data of 64 patients with single-segment lumbar degeneration undergoing posterior lumbar interbody fusion between August 2009 and June 2014 were retrospectively analyzed. Fusion device was fixed according to compression of intervertebral space. These patients were divided into compression group (n=30) and non-compression group (n=34).
RESULTS AND CONCLUSION: (1) Curative effects: Lumbar and leg pain visual analogue score, Oswestry disability index, SF-36 score and the height of intervertebral space, intervertebral foramen height and lumbar lordosis were significantly improved postoperatively in each group compared with preoperatively (P < 0.05). The intervertebral space, intervertebral foramen height and lumbar lordosis were significantly better in the non-compression group than in the compression group (P < 0.05). (2) Lumbar fusion rate: No significant difference in lumbar fusion rate was detected 6 and 12 months after surgery and during final follow-up (P > 0.05). (3) Correlation analysis: The increase of the intervertebral space and the height of the intervertebral foramen were not significantly correlated with the improvement of the clinical curative effect (P > 0.05). (4) Test results demonstrated that outcomes of the compression technique to fix the cage are equivalent to the non-compression in posterior lumbar interbody fusion. Non-compression is advantageous to increase the intervertebral space and the height of the intervertebral foramen. Both of them are conducive to the recovery of lumbar lordosis, but are not correlated with the increase in clinical curative effect.
