Principle Of Radiofrequency Nucleoplasty

The aim of percutaneous RFN like PLDD is to reduce the volume of the pathological disc with ablation and coagulation of a small portion of the nucleus (18). The ablation of a relatively small volume of the nucleus results in an important reduction of intradiscal pressure, thus inducing the reduction of disc herniation. Percutaneous disc decompression or Nucleoplasty using the Perc-DLE™ SpineWand™ relies on Coblation® technology for ablating and coagulating soft tissue, combining both approaches for partial disc removal. Coblation technology removes tissue by using a low-energy bipolar radiofrequency (RF) wave to create an ionic plasma field from sodium atoms within the nucleus (Fig. 2). This low-temperature plasma field removes tissue from the treatment area via a molecular dissociation process that converts the tissue into

FIGURE 2 Diagram representing the radiofrequency nucleoplasty procedure. (A) After the first channel is created, the SpineWand™ is rotated clockwise. (B) As the SpineWand device is curved, each rotation changes its direction and creates a new channel inside the nucleus. Approximately 6 to 12 channels are created in total, depending on the desired amount of tissue reduction.

gases that exit the treatment site. Unlike other RF systems that are temperature driven, it does not rely on heat energy to remove tissue; so thermal damage and tissue necrosis is avoided. On withdrawal of the SpineWand, the channels are thermally treated, producing a zone of thermal coagulation.

Dealing With Back Pain

Deal With Your Pain, Lead A Wonderful Life An Live Like A 'Normal' Person. Before I really start telling you anything about me or finding out anything about you, I want you to know that I sympathize with you. Not only is it one of the most painful experiences to have backpain. Not only is it the number one excuse for employees not coming into work. But perhaps just as significantly, it is something that I suffered from for years.
