In vitro and in vivo fall of intradiscal pressure with laser disc decompression.
In vitro and in vivo measurements of intradiscal pressure under load and without load, respectively, before and after laser ablation of small volumes of nucleus pulposus revealed significant falls of intradiscal pressure.  This is the basic principle underlying percutaneous laser disc decompression (PLDD).
