ABSTRACT

BACKGROUND:

Posterior lumbar interbody fusion is a typical therapeutic method of lumbar degenerative disease. Present studies suggested that adjacent segment degeneration occurs after fusion. Recently, more and more scholars paid attention to the development of non-fusion of the spine. <br>

OBJECTIVE:

To compare clinical effects of Dynesys dynamic stabilization system fixation and posterior lumbar interbody fusion in treatment of lumbar degenerative disease. <br>

METHODS:

From July 2009 to July 2011, clinical data of 56 patients with lumbar degenerative disease were retrospectively analyzed. There were 28 cases of Dynesys dynamic stabilization system fixation, and 28 cases of posterior lumbar interbody fusion. Operation time, bleeding volume, and postoperative hospitalization time were compared in both groups. Visual analog scale was used to assess pain. Oswestry disability index was utilized to evaluate clinical effects. <br> RESULTS AND

CONCLUSION:

A total of 56 patients were fol owed up for 18-24 months. Visual analog scale and Oswestry disability index scores were significantly improved at 12 months after treatment in both groups (P<0.01). Significant differences in operation time, bleeding volume, and postoperative hospitalization time were detected between both groups (P<0.01). Dynesys dynamic stabilization system group was better than posterior lumbar interbody fusion group. Range of motion was better in the Dynesys dynamic stabilization system group than in the posterior lumbar interbody fusion group (P<0.01). During fol ow-up, nail rope system and polyester sleeve loose were not detectable in the Dynesys dynamic stabilization system group. These results verified that compared with posterior lumbar interbody fusion, Dynesys dynamic stabilization system for lumbar degenerative diseases has a high safety and smal trauma, and can keep advantages of a fixed segment, and exert a certain effect on degeneration of intervertebral disc in the adjacent segment.
