Abstract :

While fusion is recommended for degenerative spondylolisthesis in select indications, microscopic decompression in low grade spondylolisthesis is being increasingly considered for pain relief as well as early mobilization. This study aims to find out the results of microscopic decompression in grade 1 spondylolisthesis and compare the results of microscopic decompression between patients with spondylolisthesis and lumbar canal stenosis without spondylolisthesis groups. Between 2007 and 2013, 108 patients with lumbar canal stenosis without spondylolisthesis and 16 patients with grade 1 degenerative spondylolisthesis underwent microscopic decompression at our center. Patients in spondylolisthesis group had good pain relief in short term, although the VAS scores were slightly higher at 6 months compared to patients with Lumbar canal stenosis(Mean VAS score 4.75 and 2.75 respectively). At 2 years, both VAS and ODI scores were comparable between the two groups (Mean ODI scores 16 and 13.6 respectively; mean VAS scores 2.43 and 1.97 respectively). We conclude that, decompression alone in grade 1 spondylolisthesis is safe, gives good results although pain relief may take a longer time compared to patients without spondylolisthesis
