Effectiveness Of Posterior Pedicle Screw Fixation System Combined With Decompression, Reduction Of Sliding Vertebral And Intertervertebral Body Fusion In Treating Lumbar Spondylolisthesis.

Objective: To evaluate the clinical efficacy of posterior pedicle screw fixation system combined with decompression, reduction of sliding vertebra and intervertebral body fusion for the treatment of lumbar spondylolisthesis.Methods: Statistics in 2013 June to 2014 June in Affiliated Hospital of Shandong University of Traditional Chinese Medicine, Department of orthopedics, wards and accept the spinal posterior open reduction and decompression and intervertebral bone grafting in 40 patients fusion and internal fixation for lumbar spondylolisthesis. Male 9 cases, female 31 cases; the age ranged from 37 to 73 years old, the average age of 55.6 years; L3 slippage in 1 case, L4 26 cases, 13 cases of L5;of which 25 cases of grade II, 15 cases of spondylolisthesis; isthmic spondylolisthesis in 18 cases, degenerative spondylolisthesis in 22 cases; all patients had low back pain symptoms. Preoperative patients were asked to take X-ray, CT and MR films. All cases were followed up for 1 months, 3 months and 12 months; lumbar X-ray and CT examination were performed at postoperative lumbar fusion rate of bone graft, lumbar spondylolisthesis rate; and for each patient subjective and objective surgery effect, by the operation on 40 cases of patients with JOA score, Macnab scoring. Retrospective analysis of follow-up data, to observe the effects of posterior open reduction, decompression and intervertebral bone graft fusion and internal fixation for lumbar spondylolisthesis treatment effect, and carries on the statistical analysis.Results: For patients with timely follow-up, all cases were followed up for 1 months, 3 months and 12 months, results in 40 cases of patients with postoperative JOA score, VAS score, low back pain of detachment indexing have different degrees of improvement and mitigation, statistical analysis was performed using SPSS software, postoperative andfollow-up when compared with preoperative have statistical significance(P<0.01); score according to Macnab criteria, excellent in 31 cases, good in 7 cases, 2 cases, poor in 0 cases, the excellent rate was 95%; all patients after 12 months of imaging examination, confirmed that the bone graft were completely fusion, lumbar spondylolisthesis were completely reset; V. pain and numbness the clinical symptoms were improved, improved the quality of life.Conclusion: Posterior lumbar spinal canal decompression,orif intervertebral bone graft fusion and internal fixation can provide good repositioning and strong fixation, spinal canal decompression and nerve root release effect is obvious, the reset rate and bone graft fusion rate is high, curative effect affirmation, and is an ideal method for the treatment of lumbar spondylolisthesis.
