PRELIMINARY RESULTS OF VERTEBRAL CANAL DECOMPRESSION BY SPINOUS PROCESS SPLITTING

ABSTRACT Objective Considering that the technique of spinous process splitting has been advocated as a less invasive treatment of lumbar stenosis, the objective of this study was to evaluate the preliminary results of this technique in the surgical treatment of lumbar canal stenosis. Methods Twenty patients with lumbar spinal canal stenosis who underwent surgical treatment for lumbar canal decompression with the spinous process splitting technique were assessed in the preoperative period and on postoperative days 1, 7 and 30 for VAS for lower back and lower limbs pain and radiographic evaluation of the operated segment. Results The mean visual analogue scale score for lumbar pain in the preoperative assessment was 4.2 ± 3.37 and 0.85 ± 0.88, 1.05 ± 1.19 and 1.15 ± 1.04 after 1, 7 and 30 postoperative days, respectively. The mean VAS score for lower limb pain was 8 ± 1.72 preoperatively, and 0.7 ± 1.13, 0.85 ± 1.04, and 1.05 ± 1 after 1, 7, and 30 postoperative days, respectively. There were no radiographic signs of instability of the vertebral segment operated in the radiographic evaluation. Conclusions Decompression of the lumbar canal through the spinous process splitting technique in patients with lumbar canal stenosis had good immediate and short-term results in relation to low back and lower limbs pain. Level of evidence IV; Therapeutic Study.
