EVALUATING THE TREATMENT OUTCOMES IN LUMBAR SPINE INSTABILITY - MULTILEVEL DEGENERATIVE DISC DISEASE BY DECOMPRESSION SURGERY METHOD, PEDICLE SCREW FIXATION AND INTERBODY FUSION
Main Article Content
Abstract
Objectives: evaluating the treatment outcomes in lumbar spine instability – multilevel degenerative disc disease by decompression surgery method, pedicle screw fixation and interbody fusion. Research methods: A retrospective descriptive research was conducted on patients diagnosed with lumbar spine instability – multilevel degenerative disc disease and opereated by decompression surgery method, pedicle screw fixation and interbody fusion at the department of neurosurgery, Cho Ray hospital from January 1, 2019, to December 1, 2020. Result: describe 45 patients operated by decompression surgery method, pedicle screw fixation and interbody fusion. The mean age was 57.7 ± 7.9 years, Proportion of males to females was 1,17. L5 radiculopathy acounted for 42,3%. The mean operative time with two – level lumbar instability was 160 ± 3,24 minutes, the mean operative time with three – level lumbar instability was 200 ± 3,81 minutes. Visual Analog Scale (VAS) after surgery when patient was hospital discharge was 3 ± 0,15. The average time of hospitalization was 3 ± 0,08 days, The overall complication rate was 6.6%, including 2 cases (4.4%) of dural tears and 1 case (2.2%) of pedicle fracture. Conclusion: The decompression surgery method, pedicle screw fixation and interbody fusion is an effective and safe surgical method for treating lumbar spine instability – multilevel degenerative disc disease.
