Abstract:
STUDY DESIGN: This is a retrospective study. OBJECTIVES: We wanted to analyze the radiological features of degenerative lumbar spondylolisthesis and retrolisthesis, and we wanted to verify what radiological factors are related to the development of the retrolisthesis. We also wanted to determine these radiological factors' clinical significance. SUMMARY OF THE LITERATURE REVIEW: There is little information about the pathological mechanism and the clinical and radiological aspects of degenerative lumbar retrolisthsis. MATERIALS & METHODS: Sixty patients were reviewed and divided into three groups. The degenerative lumbar retrolisthesis patients were in group A. The degenerative lumbar spondylolisthesis patients were in group B. Group C patients had no vertebral shift in any direction. The factors we measured were the facet joint angle, the disc height of L3-4, L4-5 and L5-S1, and the lordosis of the lumbar spine. The evaluation of the clinical results was then quantified. RESULTS: The facet joint angle showed no statistical significance between the two groups. The disc height of group A at L4-5 and L5-S1 was more decreased in group A than in group B (p<0.05). Lumbar lordosis was decreased significantly in group A (p<0.05). The preoperative pain was improved at the final follow up, but preoperative pain was significantly higher in group A than in group B (p<0.05). The clinical results were improved in each group, but there was no statistically significant difference between the two groups. CONCLUSIONS: The disc height and lumbar lordosis were considerably reduced in the patients with retrolisthesis, especially compared to those patients with spondylolisthesis. Preoperative pain was higher for the retrolisthesis patients than for the spondylolithesis patients, but there was no significant difference.
