文题释义:
Wallis系统:是由Sénégas等经过长达20余年的设计改进而制成一种腰椎棘突间内固定器。其第1代系统于1986年研制成功,是由2条粗绦纶编织成的束带固定于1个由钛合金制成的间隔器上构成的装置,可置于单个棘突节段或多个节段。第2代系统被正式命名为Wallis系统,2007年8月首次进入国内。其与第l代系统主要区别在于其间隔物的材料换成了聚醚醚酮,其弹性模量与腰椎后方结构更加匹配,可限制腰椎后伸.并承载椎间盘及小关节突的压力。
Coflex系统:是由Paradigm公司开发的一种腰椎棘突间内固定器,为钛合金材料,其中部为一U型结构,具有弹性功能,植入棘突间。使固定节段脊柱在矢状位上有50°-100°的屈伸活动范围,维持脊柱的生理活动。上、下各有两个尾翼,用于固定在棘突上,每个尾翼各有一个孔,可供缝合加强固定。在其生物力学作用上,Coflex系统除具有上述棘突间内固定器的作用外,它在增强脊柱稳定性方面的作用更加完善,并且由于其植入节段旋转中心靠近椎管的特点,增加了旋转的稳定性。

Abstract:

BACKGROUND: It is still controversial that interspinous dynamic stabilization system Wallis and Coflex which one can provide better clinical effects for lumbar degenerative disease.

OBJECTIVE: To systematically assess the clinical effectiveness and safety of Wallis and Coflex for lumbar degenerative disease.
METHODS: According to the computer-based online search of PubMed, Embase, Medline, Cochrane Library, CBM, CNKI, Wanfang Database, and VIP, articles published before August 1st, 2016 were searched. Articles about Wallis comparing with Coflex for lumbar degenerative disease were included; the quality score of methodology was assessed by MINORS. Research data abstracted and synthesized by Review Manager 5.3 were used for meta-analysis.
RESULTS AND CONCLUSION: (1) Six studies were included, and all studies were designed for non-randomized controlled trial. (2) There were no significant statistical differences in Japanese Orthopedic Association, Oswestry disability index, visual analogue scale score, Prolo functional score, segmental lordosis angle, and segment movement degree. Incidence of adverse events was significantlue scale less in the Wallis group than in the Conflex group (P < 0.05). (3) There was no significant difference in clinical efficacy between Wallis and Coflex in the early and mid-term follow-up. We can conclude that Wallis may provide better clinical safety than Coflex.
