Abstract

STUDY DESIGN: Prospective nonrandomized study.

PURPOSE: To find a possible correlation between clinical outcome and extent of lumbar spondylolisthesis reduction.

OVERVIEW OF LITERATURE: There is no consensus in the literature concerning whether a beneficial effect of reduction on outcome can be expected following reduction and surgical fusion for low grade lumbar spondylolisthesis.

METHODS: Forty six patients with a mean age of 37.5 years (age, 17-48 years) with isthmic spondylolisthesis underwent interbody fusion with cages with posterior instrumentation (TLIF). Clinical outcome was measured using visual analogue score (VAS) and Oswestry disability index (ODI). Foraminal dimensions and disc heights were measured in standard digital radiographs. These were analyzed at baseline and 1 year after surgery and changes were compared. Radiographic fusion was judged with computed tomography scans at 1 year.

RESULTS: Ninety percent of the patients had good or very good clinical results with fusion and instrumentation. Baseline and one-year postoperative mean VAS score was 6.33 (range, 5-8) and 0.76 (range, 0-3), respectively (p=0.004). Baseline and one-year postoperative, mean ODI score was 48 (range, 32-62) and 10 (range, 6-16), respectively (p

CONCLUSIONS: Neural decompression and interbody fusion can significantly improve pain and disability but the clinical outcome does not correlate with radiological improvement in the neural foraminal dimension.
