Postoperative Scar in the Control Excess of Mobility Induced by Annulus Removal on Inserting a Lumbar Disc Prosthesis

No results posted yet for this study

Summary

To implant a complete lumbar disc prosthesis removal of the anterior portion of the annulus fibrosus is required. As the anterior portion of the annulus limits the movement in extension and axial rotation, we would like to know how much increase these two disc movements and also the effect on the postoperative prevertebral scar on the reduction of these abnormal movement ranges. We also aim to see if repairing intraoperatively the anterior portion of the annulus has any advantage in the final result achieved.
