Minimally Invasive Back Pain Treatment PLDD Laser Machine
PLDD is a minimally invasive procedure that does not require general anesthesia. The laser is delivered through a needle inserted into the disc and guided by computed tomography (CT) and fluoroscopy.
CT fluoroscopy involves creating images with X-rays that are further enhanced by contrast dye. This allows physicians to see precisely where to place the needle used in PLDD.
Unlike conventional discectomy, the protruding piece of disc compressing nerve roots is not surgically removed. Instead, once the needle is in place, laser energy is delivered through the needle and into the disc.
This energy–in the form of heat–reduces the pressure inside the disc. The protruding piece of disc is therefore sucked back through the outer layer of the disc, relieving pressure on the nerve roots.
Laser disc decompression is an outpatient procedure, meaning the patient may leave the hospital or surgery center within 24 hours of surgery. General anesthesia is not used so the patient is never unconscious during the surgery. The area around the disc to be decompressed is numbed with local anesthesia.
When should consider minimally-invasive PLDD procedure
The PLDD procedure is specifically designed and developed for the cervical and lumbar indications, including:
Cervical problems
One or more cervical disc herniations
Neck pain, shoulder pain, bilateral numbnesss,
dizziness and other symptoms.Lumbar problems
Restrictive disc on CT or MRI
No intervertebral calcification, free, prolapse
Straight leg elevation test positive
Six weeks of conservative treatent is invalid
The principle of PLDD
In this procedure, laser energy is transmitted through a thin optical fiber into the disc. The aim of PLDD is to vaporize a small portion of the inner core. The ablation of a relatively small volume of the inner core results in an important reduction of intra-discal pressure, thus inducing reduction of disc herniation.
PLDD is the minimally-invasive medical procedure developed by Dr. Daniel S.J. Choy in 1986 that uses a laser beam to treat back and neck pain caused by a herniated disc.
Percutaneous laser disc decompression (PLDD) is the utmost minimally invasive percutaneous laser technique in the treatment of the disc hernias, cervical hernias, dorsal hernias (except for the segment T1-T5), and lumbar hernias. The procedure uses the laser energy to absorb the water within the herniated nucleus pulposus creating a decompression.
The PLDD treatment is performed on an outpatient basis using only local anesthesia. During the procedure, a thin needle is inserted into the herniated disc under x-ray or CT guidance. An optical fiber is inserted through the needle and laser energy is sent through the fiber, vaporizing a tiny portion of the disc nucleus. This creates a partial vacuum which draws the herniation away from the nerve root, thereby relieving the pain. The effect usually is immediate.
