Objective. Main purpose of the present paper is improvement surgical results following lumbar spine stenosis treatment.Materials and Methods. We have analysed outcomes of 124 operated on patients: 56 patients were operated on with wide decompression application and spondylosis formation (Group 1), 68 (Group 2) had mini-invasive decompression (facetectomy, flavectomy, arch marginal resection) and placement of dynamic interspinal DIAM implants. We excluded patients with spondylolytic spondylolisthesis.Results. We have found no actual difference for the following up period (from 22 months to 10.5 years) between both techniques for leg pain control. In 16.7% patients (had operation on 2 and more segments) we noticed postoperative pains lower and superior fixation area, in patients with DIAM implants after mini-invasive decompression there was no pain syndrome. In one case we found fixation system break down and it required repeated placement. Patients of both group with one-segment operation demonstrated no significant difference in spinal pain syndromes. And the patients of Group 2 had lower intraoperative blood loss and overall operative time.Conclusion. Mini-invasive decompression with dynamic implants placement is a safe and reliable alternative for spinal cord stenosis treatment comparing to wide decompression and spondylesis formation.
