Clinical Application On Transforaminal Lumbar Interbody Fusion Via Luxor System In The Surgery Of Lumbar Spondylolisthesis

Backgroud:Lumbar olisthe disease is one of the most common type of spondylolisthesis, refers to the lumbar spine a segment relative to its adjacent segment appear in displacement, vertebral body can glide forward, back and side slip.and its clinical symptoms of the mechanism is more complicated,To:(1) spondylolysis caused anomalous vertebral arch activities;(2) slip between segment sequence errors;(3) unstable periodic;(4) spondylolysis fibrocartilage tissue oppressed nerve root;(5) with disc herniation and spinal canal stenosis;(6)Small joint degeneration,etc.The aim of the Surgery is restoring the spinal sagittal plane curve, the continuity of rebuilding the three column structure, restoring intervertebral height and ensure smooth disconnect segment fusion to avoid slip again.Surgery is often used in situ fusion in the past, such as intervertebral bone graft fusion or bone graft fusion between transverse process, postoperative often tend to slip again;In recent years, the development of spine biomechanics and the application of new type of spinal internal fixation system, it has a new understanding to Lumbar fusion and reset. posterior lumbai interbody fusion,(PLIF) joint posterior pedicle screw fixation, lamina resection and nerve root release expand cage decompression surgery is widely used and promotion, and obtained a certain clinical curative effect.But surgery of vertebral muscles by extensive dissection, intraoperative excision of spine,lamina composite longitudinal ligament, ligament damage to the spinal posterior column is larger, resulting in decreased spinal stability and postoperative legacy in patients with low back pain for a long time, in the end,it affect the patients quality of life.With the development of minimally invasive techniques,Luxor expand minimally invasive channel system aided by the vertebral side crack more muscular clearance into the longest road, minimally invasive treatment of lumbar degeneration operation method is widely used, it has small trauma, intraoperative without extensive stripping vertebral muscles, after removal of longitudinal ligament complex;The characteristics of quick postoperative recovery, fewer complications.Objective:To observe the clinical curative effect of transforaminal lumbar interbody fusion via luxor system in the surgery 0f lumbar spondylolisthesis.Methods:Retrospective analysis the 36 cases that during October 2012-February 2014, whom were adopted luxor channel under TLIF surgery with lumbar olisthe, to observe patient’s ODI score and VAS score with postoperative 3 months and one year, understanding of intervertebral fusion and internal fixation with or without loose, fracture and so on.Results and Conclusion:All of the surgery were completed, no patients had cerebrospinal fluid leakage and nerve injury,1 case of postoperative caused incision infection, infection have been controled, after antibiotic treatment for 10 days,the other patients were class a healing of incision.All patients were followed up, at the time of postoperative 3 months and 1 year follow-up after,the ODI score and VAS score compared with preoperative were significant recovery, the differences were statistically significant(P<0.05), the ODI score and VAS score between 3 months and 1 year follow-up were similar(P>0.05).Both the ODI score and VAS score were significant improvements:ODI,(65.3±14.8)%;VAS,(58.2±12.0)%.luxor TLIF technique to treat lumbar olisthe under the channel of minimally invasive treatment of lumbar olisthe was a feasible operation method, it not only can effectively correct the lumbar spine deformity, maintain spinal biomechanics stability, improve symptoms, also can reduce the incidence of postoperative patients with low back pain, a higher quality of life.
