OBJECTIVE: To explore the safety and short-term efficacy of the posterior approach of the Dynesys dynamic neutralization system for @entity179 . METHODS:     From March 2008 to March 2010, 32 cases of @entity179 , 19 @entity1 and 13 @entity1 , (mean age 58    5.2, range, 43-78 years), were treated with posterior laminectomy and Dynesys internal fixation. All @entity1 had a history of over 3 months waist or @entity158 that had not been relieved by conservative treatment. There were 10 cases of single lumbar intervertebral disc protrusion, 14 of @entity2649 , 5 of degenerative lumbar isthmic spondylolisthesis, and 3 of recurrent lumbar disc protrusion after surgery. A visual analogue score (VAS) was used for @entity158 assessment, and the @entity717 index (ODI) for functional evaluation of clinical outcomes. RESULTS: All @entity1 were followed up for 6-23 months (mean, 16.4    5.5 months). Forty-one segments in 32 @entity1 were stabilized; 23 cases (71.9%) underwent single-segmental stabilization, and 9 (28.1%) two-segmental stabilization. VAS of @entity158 , root and @entity1643 was significantly improved postoperatively. The ODI improved from preoperative 69%    12.6% to postoperative 28%    15.7% (P < 0.001). On the stabilized segment and adjacent segments above and below, the range of movement showed no statistical difference; no loosening of screws, cord and polyester spacer occurred. CONCLUSION:     The Dynesys dynamic neutralization system combined with decompression can achieve satisfactory short-term clinical results in @entity179 . This procedure system not only reduces back and @entity158 , but also preserves the mobility of fixed segments, minimizes tissue injury and avoids taking bone for spinal fusion.
