Objective:
To study the risk factors of unsatisfactory clinical results after percutaneous laser decompression of the lumbar intervertebral disc (PLDD).
Material And Methods:
A retrospective observational single-center study included medical records of patients who underwent lumbar PLDD for degenerative spine disease. We analyzed clinical and instrumental parameters potentially affecting the results of lumbar PLDD.
Results:
Clinical study included 82 patients who underwent PLDD for lumbar intervertebral disc degenerative disease. Mean postoperative follow-up period was 30.8±13.3 months. In 22 (26%) patients, unsatisfactory clinical outcomes were observed. According to binary logistic regression model, comorbidities (p=0.03), duration of disease over 12 months (p=0.03), low preoperative quality of life according to ODI score (more than 50%) (p=0.04), high body mass index (over 25 kg/m2) (p=0.02), severe intervertebral disc (p=0.04) and facet joint degeneration (p=0.01) and intervertebral disc height decrease more than 50% (p=0.01) were significantly associated with unsatisfactory clinical outcomes after lumbar PLDD for degenerative spine disease.
Conclusion:
Identification of these risk factors of unsatisfactory clinical outcomes is important stage of preoperative preparation in patients scheduled for lumbar PLDD.
