Clinical Application of Single-side Pedicle Screw Fixation for Lumbar Posterior Fusion under Quad-rant System
Abstract：Objective To assess the clinical value of minimally invasive single-side pedicle screw fixation for lumbar pos-terior fusion. Methods A consecutive series of 45 patients who had undergone lumbar spinal fusion of 1 segment to treat de-generative lumbar disease was analyzed,which underwent TLIF with unilateral pedicle screw fixation under Quadrant system. More than 1 year all the patients were followed up with VAS scores and Oswestry disability questionnaire. All the patients ac-cepted X-line/ CT evaluation to compare the intervertebral height/ fusion rates at the operative level pre-operation with post-op-eration. Results The ODI score,VAS score and intervertebral height were significantly improved when compared with preop-erative one. The fusion rate were 100% . Conclusion Single-side pedicle screw fixation assisted by under Quadrant system caused less iatrogenic injury and had positive efforts post-operation. It can provide a simple and reliable choice in degenerative lumbar disease.
