Abstract: Background: The degenerative spondylolisthesis is a common problem treated by an orthopaedician in day to day practice. The available data on the outcomes of posterior lumbar interbody fusion with posterolateral fusion in terms of functional and radiological parameters is scant. Hence we had evaluated the functional and radiological outcomes in degenerative spondylolisthesis patients treated with posterior lumbar interbody fusion with posterolateral fusion.
Material and Methods: A prospective interventional study was undertaken among adult patients with degenerative spondylolisthesis admitted to the tertiary care hospital were included. Seventy-five adult patients who had degenerative spondylolisthesis treated with a posterior lumbar interbody fusion with posterolateral fusion. The patients were followed up at 3rd, 6th and 12th postoperative months.
Results: The mean age was 62.9 years and more female patients are present in our study. The improvement in pain determined by visual analog scale (VAS) was statistically significant at 3rd, 6th and 12th months follow up visits when compared to baseline.In our study with respect to the patient to return to work, 63 (84%) patients show an excellent result, taking the result as satisfactory. Our study show posterolumbar interbody fusion level 5: seen in 75 levels, level 4: seen in 07 levels and posterolateral fusion grade A score is seen in 67 levels in with minimal complication rate.
Conclusion: This study was able to show that posterior lumbar interbody fusion with posterolateral fusion had a good clinical outcome.
