Percutaneous Laser Disc Decompression (PLDD)
Laser Use in Orthopedics & Spine
Microsurgical Solution for percutaneous pain management
EVOLVE® in PLDD
During treatment with EVOLVE®, a small volume in a closed hydraulic space (nucleus pulposus) is being vaporized to achieve a reduction of intra-discal pressure (thermic ”shrinking effect“). The reduction in volume and pressure of the pathological disc induces the reduction of disc herniation and thus a reduction in nerve root compression. Furthermore, it leads to the denervation of the pain receptors (nociceptive nerves) of ingrowing nerves from dorsal ligament into annulus fibrosus. In addition to the above, pain causing facette joints can be treated in the same session to give an even better relief in a combination therapy.
The therapeutic effect of intra-discal laser therapy is based on the combination of the specific treatment characteristics. Thanks to the standardized treatment protocol and heating effect, the surgeon creates a defined shrinkage of the disc. Due to vaporization of disc liquid, intra-discal pressure decreases. The laser energy used in minimally invasive treatment strengthens the disc through laser-stimulated scarring as the collagen structure changes. Neo-vascularisation of inflamed discs can be switched off with denervation of pain receptors inside the annulus fibrosus.
Tissue interaction with LEONARDO® DUAL
The LEONARDO® DUAL platform is based on the absorption characteristics of both 980 nm and 1470 nm wavelengths, which, thanks to its outstanding interaction in water and haemoglobin and moderate penetration depth into disc tissue, enables procedures to be carried out safely and accurately, especially in proximity of delicate anatomical structures.
Microsurgical precision is guaranteed by the technical characteristics of the special PLDD laser fibers, which allow for surgical effectiveness, ease of handling, and maximum safety.
The use of flexible tactile laser fibers with core diameters of 360 micron in combination with the microsurgical PLDD enables a very precise and accurate access and intervention to sensitive areas like the cervical and lumbar disc zones on the basis of clinical therapeutic needs.
PLDD laser treatments are mostly used after non-successful conventional therapeutic options under strict MRT / CT control.
