The Clinical Curative Effectcon Trastanalysis Between Dynamic Neutralization System(Dynesys) And Posterior Spinal Fusion In Treatment Of Lumbar Degenerative Disease

Objective: Through the methods of clinical comparative analysis, research of dynamic Neutralization system(Dynesys) and the therapeutic effect of posterior spinal fusion in the treatment of lumbar degenerative disorders, and to guide the clinical application.Method: 30 patients with lumbar degenerative diseases in 2012 March to 2012 October selectedoperation income of hospital treatment of patients, which adopt Dynesys surgery(observation group) and 15 cases of patients, with posterior spinal fusion(control group) 15 cases, follow-up time was more than 20 months, through the records of patients before and after surgery and at the final follow up currently more popular at home and abroadobservation index, were analyzed retrospectively contrast effect.Results: 2 groups of participants in the study were age, gender, number, type of disease, duration of follow-up and other baseline data analysis showed no statistical significance(P > 0.05), with homogeneity;There was statistical significance in operative time, bleeding amount is the difference in the two groups(P < 0.05), the observation group was better than that of the control group; The last fol low-up pain visual analogue score after operation in the two groups(Visualanalo gue, scale, VAS), Oswestrydisability index score(Oswestry disability index, ODI)compared with that before operation were greatly improved, the difference was statistically significant(P < 0.05), but no significant difference between the two groups(P > 0.05); The two group after the last follow-up operation intervertebra l height were lower than before operation, but the difference between the two groups had no statistical significance(P > 0.05);the two group of postoperative int ervertebral space near the height increase, compared with the preoperative were statistically significant(P < 0.05), but the observation group was better than that of the control group; The last follow-up after operation, the control group had healed, operation Intervertebralactivity(Range of motion, ROM) of 0 DEG, and the observation group to retain part of lumbar spine motion, the difference was statistically significant(P < 0.05). The observation groupadjacent segment ROM compared with the preoperative decreased, no significant difference(P > 0.05), the control group of adjacent segment ROM increased significantly than that before operation. The difference was statistically significant(P < 0.05).Conclusion: In the near future curative effect contrast, dynamic neutralization system(Dynesys) andposterior spinal fusion is not very different, clinical on have achieved good effect, patients withpostoperative symptoms were were improved obviously, but the Dynesys internal fixation can be part of the reservation operationsection ROM, can reduce the adjacent segment compensatory activity caused by operation segmental fixation increases, thereby slowing the adjacent segment degeneration of intervertebral disc, and can shorten operation time, reduce bleeding. A good grasp of the indications of the premise, it is worth populariz ing in clinic.
