OBJECTIVE: To explore the clinical effects of unilateral pedicle screw fixation and transforaminal lumbar interbody fusion (TLIF) through paraspinal muscle approach for recurrent @entity890 combined with lumbar instability. METHODS: A total of 35 @entity1 with recurrent @entity890 combined with lumbar instability were treated between March 2008 and May 2010, including 15 @entity1 managed by the paraspinal muscle approach with unilateral pedicle screw fixation and transforaminal lumbar interbody fusion (TLIF) (unilateral fixation group) and 20 @entity1 by the posterior midline approach with bilateral pedicle screw fixation and posterior lumbar interbody fusion (bilateral fixation group). Operation time and intraoperative @entity190 were observed, preoperative and postoperative JOA score and VAS score in low back @entity158 and @entity158 , the interbody fusion condition were compared between two groups. RESULTS: All @entity1 were followed up from 6 to 30 months with an average 16.8 months. All clinical symptoms had obviously improved postoperatively. X-rays showed good interbody fusion (only 1 case did not obtain fusion in bilateral fixation group) without cage displacement or settlement and implant loosening or breakage. There was significant difference in operation time and the intraoperative @entity190 between two groups (P < 0.05). Postoperative JOA score had obviously decreased than preoperative one (P < 0.05). At 1 week after surgery, there was significant difference in VAS score of low back @entity158 between two groups and there was no significant difference in VAS score of @entity158 between two groups (P > 0.05); at final follow-up, there was no significant difference in VAS score of low back @entity158 and @entity158 between two groups (P > 0.05). CONCLUSION: Two methods both can obtain satisfactory effect in treating recurrent @entity890 combined with lumbar instability. Through the paraspinal muscle approach with unilateral pedicle screw fixation and TLIF has advantages of smaller surgical incision, shorter operation time, less intraoperative @entity190 , @entity1643 after operation, etc.
