Clinical And Radiologic Study Of WavefleX For Lumbar Degenerative Disease

Objective:To study the technology using WavefleX dynamic stability system, respectively WavefleX dynamic stability system combined with the traditional screw rods technology, simple to use traditional screw rod fixation system fusion technology to treat lumbar degenerative disease, this study based on the fusion, the fusion and fusion with the non fusion surgery clinical observation data of comparative analysis, dynamic stability analysis application WavefleX system technology and traditional nail stick fixed fusion technology in the treatment of lumbar degenerative disease of the reliability and security, at the same time evaluating WavefleX dynamic stability system treatment clinical curative effect of lumbar degenerative disease.Methods:Clinical case study USES the contrast before and after operation and parallel comparison test method. Statistical analysis in July 2013 to January 2015 in shandong university hospital of traditional Chinese medicine spine orthopaedic surgery treatment of 56 patients with degenerative disease of the lumbar spine, depending on the selected operation patients can be divided into: group A(13 cases of treatment with pure WavefleX dynamic stability system); Group B(8 cases by Wavefle X dynamic stability system combining traditional nail treatment technology); Group C(A + B group, A total of 21 cases using WavefleX dynamic stability system treatment); Group D(35 cases of simple to use traditional fixed nail rod system fusion technology treatment). Follow-up of 6 to 20 m o n t h s, a n a v e r a g e o f 1 1 m o n t h s, 5 6 p a t i e n t s w e r e follow-up. In the last one as the final evaluation on the basis of follow-up data. Through the observation of two groups of cases respectively operation time, intraoperative blood loss, VAS pain score and Oswestry disability index, evaluation degree of symptoms improvement, neurologic status and calculate its at the same time period. At the same time, based on the preoperative imaging data of postoperative evaluation, evaluation WavefleX dynamic stability system, traditional screw rod fixation surgery effect on lumbar spine.Results:through SPSS16.0 statistical analysis, using t- test, inspection or analysis of variance, operation time, A group D no difference(P > 0.05), intraoperative blood loss significantly less than group A group D(P > 0.05)., VAS pain score, Oswestry disability index is group D C group were no significant differences. Postoperative patients of group C compared with group D indexes compared with preoperative two grades improved significantly, with significant difference(P < 0.05). Lumbar integral of motion(ROM) ° preoperative A and group B compared with group D(P > 0.05), postoperative A and group B compared with group D(P < 0.05), A, B, D group at the end of the postoperative follow-up time is to some extent reduce the preoperative(P < 0.05). WavefleX activity degree of dynamic stability system fixed section at the end of the postoperative follow-up time compared with preoperative(P < 0.05). Compared with preoperative, group C WavefleX dynamic stability system fixed segment(ROM2) compared with preoperative adjacent segmental mobility increased to some extent, there was no statistically significant difference, P > 0.05), postoperative point measurements at the same time compared with group D fixed segment adjacent segmental compare L2/3, L3/4, L4/5 and L5 / S1 were lower than control segment activity(P < 0.05). Preoperative measurements compared with group D fixed segment adjacent segmental L2/3, L3/4, L4/5 and L5 / S1 comparison(P > 0.05) in group A and group D lumbar lordosis Angle(LL) whole postoperative follow-up results preoperative increased obviously(P < 0.05) in preoperative compared the two groups have no significant difference(P > 0.05), postoperative follow-up the results of measurements in group A big in the D group(P < 0.05). Group C WavefleX dynamic fixed segment of the segmental lordosis Angle(alpha), the rate of intervertebral disc(IVS) there was no statistically significant difference compared with preoperative(P > 0.05).Conclusion:compared with the traditional screw rod WavefleX dynamic stability system, bone graft fusion and internal fixation with less bleeding, for patients with traumatic surgery is relatively small, the advantages of the sports load from adjacent segments. Dynamic stabilization system using WavefleX treatment to prevent and control the progress of the adjacent segment degeneration. In the strict control of surgical indications, sufficient preoperative preparation, intraoperative standardized operation and correct perioperative management and postoperative function exercise under the premise of simple treatment, using WavefleX WavefleX dynamic stability system dynamic stability system combined with the traditional screw rods technology treatment, simple to use traditional screw rod fixation fusion technology treatment can obtain satisfactory curative effect.
