Abstract

|
Purpose: This study was evaluated the effects of nucleoplasty and chemonucleolysis, as interventional treatments for herniated intervertebral disc disease, on spinal tissues.
Methods: Nucleoplasty using plasma beam and chemonucleolysis with collagenase were conducted on the spinal motion segments that were dissected from of human cadaver spine under fluoroscopic guidance. After the procedure, the intervertebral discs were transected, and the changes in gross findings were examined. Subsequently, the influence of the procedure on the nucleus pulposus, annuls fibrosus, and endplate was analyzed through a pathologic examination.
Results: Nucleoplasty was confirmed to eliminate the local range of tissues in nucleus pulposus according to the procedure tract and to not affect other tissues. In chemonucleolysis, we found that collagenase diffused from the surgical site within the nucleus pulposus and was not present in the annulus fibrosus and endplate.
Conclusions: The clinically-used interventional treatments that were investigated here were not found to do not cause additional damage to areas other than those targeted.
