ABSTRACT
Interspinous dynamic stabilization is popular in the non-fusion spine surgery.It is characterized in the motion preservation of segmental lumbar,avoiding the stress change after fusion surgery and adjacent disc degeneration.Interspinous dynamic stabilization systems have got fast development and are widely used in the treatment of lumbar spine disease.As an innovation of traditional fusion surgery,the clinical evaluation is the focus of spine surgeon.In this paper,the recent studies of the clinical evaluation of interspinous dynamic stabilization are reviewed.
ABSTRACT
[Objective] To evaluate the early effect of posterior dynamic lumbar stabilization in lumbar degenerative disease.[Methods]The clinical outcomes of 31 patients with lumbar degenerative disease treated by posterior decompression with Wallis posterior dynamic lumbar stabilization implant or combined with posterior lumbar fusion were retrospectively studied,and assessed with visual analogue scale(VAS)and spinal operative standard of Chinese Medical Association.The early effect and complications associated with Wallis posterior dynamic lumbar stabilization were recorded.[Results]The operative procedure of Wallis posterior dynamic lumbar stabilization implant was easy and less invasive.The VAS scores were 7.9?2.0,2.6?1.2 and 1.7?0.8 at one day preoperatively,two week postoperatively and final follow-up,respectively.The good to excellent result was 94.4% at the lastest follow-up.No compliction related with Wallis posterior dynamic lumbar stabilization was found.[Conclusion]It is easy and safe to use Wallis posterior dynamic lumbar stabilization in treatment of degenerative lumbar disease,and the early effect is good.The Wallis system provides an alternative for treatment of lumbar degenerative disease.
