Limited Spinal Canal Decompression For The Treatment Of Lumbar Degenerative Scoliosis Clinical Curative Effect Observation

Objective Limited analysis of spinal canal decompression and internal fixation and interbody fusion treating lumbar degenerative scoliosis (Degenerative lumbar scoliosis, DLS) clinical curative effect, for clinical treatment of lumbar Degenerative scoliosis provide evidence for the selection of operative methodsMethods Statistical analysis from December 2013 to December 2015 in our hospital during the ningxia autonomous region people’s hospital orthopedic spine and diagnosis of lumbar degenerative scoliosis patients,40 patients with choice conforms to the inclusion criteria, all patients were limited spinal canal decompression and internal fixation and interbody fusion treatment, according to the patients before and after surgery Cobb Angle, Oswestry disability index assessment (Oswestry dysfunction index ODI) symptoms, Visual simulation assessment (Visual analogue scale VAS), the results were statistically analyzed.Results 40 patients postoperative safely back ward, perioperative period no cases of infection, all patients with low back pain symptoms have been varying degrees of ease, back function improved significantly, the quality of life and social function improved significantly. Comparison before and after surgery in patients with Cobb Angle, preoperative Cobb Angle is (12.3°～18.6°), an average of 13.9°; Postoperative Cobb Angle is (10.7°～16.5°), an average of 11.7°, the improvement rate was 15.8%, the difference was statistically significant (t=4.33, P< 0.05).Comparing VAS scores before and after surgery, patients with preoperative VAS score is 5-8 points, the average of (6.02+0.82); Postoperative VAS score is 1-4 points, the average of (2.12-0.78), the difference was statistically significant (t= 12.66, P<0.05). Comparison before and after surgery in patients with ODI index, index of preoperative ODI score is (42.00-85.00)%, the average of (66.17+9.96)%. Postoperative ODI index score is (11.00-41.00)%, the average of (22.39+8.92)%, the difference was statistically significant (t= 10.34, P<0.05),40 patients postoperative ODI improvement rate was 66.16%.Conclusion Through this study, according to the results of limited spinal canal decompression and internal fixation and interbody fusion can effectively alleviate symptoms of low back pain, intraoperative sufficient decompression and bone graft fusion and internal fixation, which can effectively prevent postoperative due to lumbar instability influence long-term clinical curative effect. The operation advantage:limited vertebral canal decompression can be on the premise of fully release nerve root to minimize the damage to the vertebral plate, internal fixation with bone graft fusion to correct scoliosis and to strengthen the stability of the spine, to shorten the postoperative patients wear support and rehabilitation exercise time.
