Abstract
BACKGROUND: In recent years, the technique of the spinal nonfusion is the focus for researching and debating in the filed of spinal su rgery. Coflex interspinous process dynamic reconstruction system is a posterior nonfusion equipment, despite of used for a long time abroad, but in China is still in a trail stage.OBJECTIVE: To explore the indications of Coflex interspinous process dynamic reconstruction system in the treatment of lumbar degenerative diseases and its early clinical efficacy.METHODS: From October 2008 to September 2010, 31 patients with lumbar degenerative diseases were treated by Coflex interspinous process dynamic reconstruction system, of which 18 cases were followed up more than 1 year, and we analyzed and summarized their clinical data . Surgical procedures were posterior resection of nucleus pulposus, decompression of spinal canal and implantation Coflex interspinous dynamic reconstruction system, only 1 patient was implanted 2 Coflexes in surgery. The patients' JOA, VAS, and ODI scores, the intervertebral height of the implanted segment and the range of motion (ROM) of adjacent segments, and the angle of the upper and lower plates of the Coflex in each position were evaluated before and after the operation, and at every follow-up.RESULTS AND CONCLUSION: All cases were followed up for 15.4 (12-20) months. The patients' JOA, VAS, ODI scores have been significantly improved at the last follow-up. The intervertebral height of the implanted segment and the ROM of adjacent segments had no significant change (P ＞ 0.05), the angle of the upper and lower plates of the Coflex in the hyperextension position is significantly increased than in the neutral position at the last follow-up (P ＜ 0.05). Coflex interspinous process dynamic reconstruction system is a safe and effective technique for treatment lumbar degenerative diseases ,such as lumbar disc herniation, spinal stenosis and lumbar instability, and it not only have little impact on physical fu nction of lumbar but also effectively share the load when the lumbar spine extend backward , so its early clinical efficacy is positive.关键词
