Treatment for unstable lumbar vertebrae by posterior lumbar interbody fusion with cage

Objective To evaluate the treatment of posterior lumbar interbody fusion with cage. Methods Posterior lumbar interbody fusion with cage were performed in 26 patients with chronic low back pain. Results After follow-up for 6~12 months, preoperative symptoms of all the 26 patients were significantly improved. Clinical effective rate and satisfactory rate was 100% and 92.3%(80.8% excellent, 11.5% good), respectively. 25 of the 26 patients achieved successful fusion and the bone union rate was 96%. One patient was complicated with a transient dysfunction of peripheral nerves. Conclusion The treatment of posterior cage implantation has been found to be an effective, reliable, rapid, safe procedure for lumbar interbody fusion. The results of our practice demonstrated it produced a high fusion rate and clinical success with rare, serious, or permanent complication.
