The importance of ligamentotaxis and remodeling concerning to restore the spinal canal after spine fractures is controversial discussing. Ligamentotaxis meaning the indirect reposition of retropulsed intraspinal bony fragments by the application of lordosis and distraction forces. Remodeling meaning the resorption of intraspinal bony fragments through the pulsations of the intraspinal venosus plexus and oscillations of the liquor cerebrospinalis. To verify the efficiency of ligamentotaxis and remodeling we have been made a prospective study over 6 years at the trauma surgery unit at the Martin- Luther- University Halle. For Statistical analysis paired t- test was used. The spinal canal area was measured by computer aided planimetry. In the first group, 130 patients with preoperative and final CT scans at the time of implant removal, we found a restoration of the spinal canal area from initial 71,3% to 90,7% (p=0,000) of normal. In the second group, 82 patients with preoperative, postoperative and final CT scans at the time of implant removal, we found a restoration of the spinal canal area from initial 67,4% to postoperative 78,3% (p=0,000) and to 89,8% (p=0,000) of normal. So this study demonstrated the efficiency of ligamentotaxis and remodeling. |
