The Initial Efficacy Of The Wallis Interspinous Process In The Treatment Of Discogenic Low Back Pain

Discogenic low back pain, which is one of the most common disease clinical spine and an early manifestation of lumbar degenerative disease, belongs to Chinese medicine of low back pain, arthralgia and is harmful to patient's daily life. For more than half a century, discogenic low back pain has been the research focus of the majority of orthopedic surgeons. Along with the further research of it, etiology, mechanisms and treatment of discogenic low back pain already get deeper understanding and development. On cure, although conservative treatment, intervention and minimally invasive techniques have certain advantages, the long treatment cycle and repeated condition exist. Interbody fusion, which is considered as the "gold standard" treatment of discogenic low back pain, often make a change of spine biomechanics and the stress concentration of adjacent vertebral bodies, which accelerate the degeneration of vertebral body. So the complications of interbody fusion are getting more and more attention. Based on the limitations of the fusion surgery, spine non-fusion technology occurs,specifically manifested in dynamic fixation system, such as the Wallis system, DYNESYS system.The article reviews the concept, traditional Chinese medicine and modern medicine cognition, etiology, pathogenesis, disc degeneration process and biomechanical characteristics diagnosis and treatment of discogenic low back pain. The paper also introduces a series of treatment progress in details,including conservative, minimally invasive treatment, integration and non-integration. Clinical research mainly focuses on the treatment effect of16patients in300cases of lumbar degenerative disease in Dongzhimen Hospital of Beijing University of Chinese Medicine Orthopedic Center.Objective:To observe the early clinical results and to explore the mechanisms and advantages of the Wallis interspinous stabilization system in the treatment of discogenic low back pain.Research Methods:Between August2007-December2010,selecting16patients with discogenic low back pain in300cases of lumbar degenerative disease to study in Dongzhimen Hospital of Beijing University of Chinese Medicine Orthopedic Center.The clinical following-up was be done for12-24month. To use the method of retrospective study,16patients were observed before surgery, after two weeks, three months, six months.1year, the last following-up by VAS score, JOA score, and ODI score, and imaging studies. We applicate the SPSS17.0Software to statistics analysis for relevant information.The results:The patients were followed up for various periods of pain visual VAS score, JOA score, ODI score and preoperative compared to a significant improvement, with significant differences (P<0.01).2weeks after surgery, and postoperative3months,6months,1year and last there are significant differences (p<0.001), after March and after6months,1year and the end of second between there are significant differences (p<0.05), after6months,1year, the difference between the last significant (p>0.05), patients with postoperative pain has been gradually eased.Conclusion:The Wallis interspinous stabilization system is a new attempt in the treatment of discogenic low back pain. It has the advantages of simple, minimally invasive, safe, and easy renovation. It can also retain the integrity of the anatomical structure of the activity of the lumbar segments, while maintaining the stability of the segment, and to promote the restoration of disc degeneration, and the system has the ability to maintain a certain spinebiological function.It plays a role in the prevention of adjacent segment degeneration. Therefore, the Wallis interspinous stabilization system in the treatment of discogenic low back pain has great advantages, but it needs for further clinical observation in long-term efficacy.
