Waveflex弹性固定与髓核摘除纤维环修复重建腰椎间盘突出患者脊柱稳定性
Waveflex elastic fixation and discectomy annulus in repair and reconstruction of spinal stability in patients with lumbar disc herniation
摘要
Abstract
BACKGROUND:For reason of pathological particularity, treatments for young adult patients with lumbar disc herniation require more demanding procedures. Traditional discectomy and rigid fixation and fusion receive a lower clinical satisfaction rate because of their concomitant complications. Waveflex is a semi-rigid fixation system with non-fusion pedicle screws. Once combined with the technology of annulus repair, it can maintain the normal movement of the segments, and can thus raise clinical satisfaction rate. OBJECTIVE:To evaluate the short-term efficacy of the treatment of young adult lumbar disc herniation through the technology of the posterior Waveflex non-fusion pedicle screw elastic fixed smal window nucleus pulposus extirpation associated with annulus repair. METHODS: Thirty-eight patients with lumbar disc herniation were involved in this study, among which, 18 cases in the elastic fixation group were subjected to a posterior lumbar smal window nucleuspulposus extraction along with annulus repair together bound with Waveflex elastic fixation; the rest 20 cases in the nucleus pulposus removal group underwent simple nucleus pulposus extirpation. After these operations, a series of folow-up study was conducted, including: folow-up analysis of clinical efficacy and complications, colection of low-back pain visual analogue scores, colection of Japanese Orthopaedic Association scores (JOA), regular assessment of Oswestry dysfunction index, and reevaluation of the lumbar lateral radiographs related indicators. RESULTS AND CONCLUSION:Folow-up visits to the patients were conducted 12-20 months later since the operations. Both groups showed a better performance than before treatment in the pain visual analogue scale, low back pain JOA score, and Oswestry dysfunction index of low-back pain (P < 0.05) during the last visit. The pain visual analogue scale, low back pain JOA score, and Oswestry dysfunction index of low-back pain in the dynamic fixation group were superior to those in the nucleus pulposus removal group (P <0.05). Stil in the last folow-up, operative segment disc height in the dynamic fixation group was greater than that before treatment, and the operative segment range of motion was smaler than that before treatment (P <0.05). These results suggest that compared to nucleus pulposus removal, Waveflex system associated with nucleus pulposus excision annulus repair has a more satisfactory effect in the early recovery of lumbar spine function and exerts a positive effect on the stability of the operated segments in the treatment of lumbar protrusion of the intervertebral disc in young adults.关键词
