Abstract:
ObjectiveTo investigate the changes of the opposite structures with the minimally invasive transforaminal lumbar interbody fusion and unilateral fixation.MethodsFrom January 2009 to January 2010,a total of 34 patients with low back pain underwent the minimally invasive transforaminal lumbar interbody fusion and unilateral internal fixation were retrospectively analyzed.Visual analogue scale (VAS) and Japanese Orthopaedic Association(JOA) low back pain scores were used to assess the outcome of the surgery.All patients were followed up for at least 6 months after surgery.The opposite structures of the segments with fusion and unilateral fixation were investigated with CT scans.CT imaging of the patients with opposite low back pain after surgery were analyzed for exploring possible causes of the pain.ResultsThere were significant differences between the pre- and post-operation in VAS and JOA scores(P＜0.01).Four patients met pain in the opposite lumbosacral area after surgery.The CT scans showed that the rebuilding of the lordosis and disc height of the opposite side were more difficult.Rotation could happen in the progress of surgery.For the 4 patients with opposite low back pain after surgery,the insufficiency of the rebuilding of lordosis and disc height of the opposite side,and the rotation between the vertebras were more obvious,and changes were observed in the opposite facet joint on the post-operational CT scan of one patient.Conclusion The minimally invasive transforaminal lumbar interbody fusion and unilateral fixation are effective for patients with low back pain.It's important to pay more attention to the rebuilding of the lordosis and disc height of the opposite side,and the rotation of the vertebras in the surgery.
