The aim of percutaneous laser disk decompression(PLDD) is to vaporize a small portion of the nucleus pulpous of an intervertebral disk, thereby reducing the volume and pressure of a diseased disk. Pressure reduction creates a pressure gradient leading to migration of the herniated portion away from the involved nerve root. This is based on a physical principal of Pascal Law. In an enclosed hydraulic space, small change in volume will result in a large change in pressure.
The Advantages of the Laser Discectomy over conventional surgery include;
Performed as an out patient procedure
Do not preclude alternative surgical options
Reduced risk of complications
Usually provide immediate relief of symptoms
Reduced soft tissue injury
No bone is sacrificed
No epidural fibrosis
