Degenerative lomber spondylolisthesis is defined as slip of the vertebrae without any vertebral arc defect. The displacement commonly occurs at L4-L5 level, rarely in adjacent segments. In degenerative lomber spondylolisthesis, pathology starts with intervertebral disc and facet joint degeneration. Clinically it can be variable as asymptomatic or mechanical back pain, neurological claudication and incontinence. In addition to standard radiography, computerized tomography, myelography and magnetic resonance imaging can be used for diagnosis. Since it is minimally invasive and shows the soft tissue components better, the first choice should be magnetic resonance imaging. About %10–15 of degenerative lomber spondylolisthesis patients are treated surgically. The situation gets worse in %83 of the patients who have neurological claudication and vesicorectal problems, and have not been treated. In surgical treatment options, there are decompression and decompression with fusion; the fusion options are posterolateral and interbody fusion (TLIF, PLIF and ALIF).
