What is the PLDD ?
Percutaneous laser disc decompression (PLDD) is the utmost minimally invasive percutaneous laser techniquein the treatment of the disc hernias, cervical hernias, dorsal hernias(except for the segment T1-T5), and lumbar hernias. The procedureuses the laser energy to absorb the water within the herniated nucleuspulposus 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.
The Principle of PLDD?
In the procedure of percutaneous laser disc decompression, 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.
WHO SHOULD CONSIDER PLDD?
The PLDD procedure is specifically designed and developed for the cervical and lumbar indications, including:
*Severe leg, arm, neck or lower back pain.
*Pain that has not responded to six weeks of conservative treatments- rest, meds or physical therapy.
*Herniated lumbar discs confirmed by x-ray studies that may include one or more of the following:
Magnetic Resonance Imaging (MRI), CAT Scanning, Myelography, Discography.
Treatment Handlepiece for PLDD :
Applications
- Intra-discal application on cervical spine, thoracic spine, lumbar spine
- Medial branch neurotomy for facet joints
- Lateral branch neurotomy for sacroiliac joints
Benefits of the minimally invasive PLDD procedure
- Local anaesthesia allows the treatment of patients at risk.
- Very short operating time compared with open procedures
- Low rate of complications and postoperative inflammation(No soft tissue injury,No risk of epidural fibrosis or scarring)
- Fine-needle with very small puncture site and therefore no need for sutures
- Immediate significant pain relief and mobilization
- Shortened hospital stay and rehabilitation
- Lower costs
PLDD: Both fine-needle and fiber are introduced into the diseased disc under fluoroscopy.
Procedure:
PLDD procedure is performed using local anesthesia. Optical fiber is inserted in special cannula under fluoroscopic guidance.After applying contrast to the facet it is possible to check cannula's position and the condition of the disc bulge. Starting laser initiates decompression and lowers intradiscal pressure.
The procedure is done from the posterior-lateral approach with no interference to vertebral canal,therefore,there is no possibility of damaging a reparative treatment,but there is no possibility to reinforce annulus fibrosus. During PLDD disc volume is minimally decreased,however,disc pressure can be significantly lowered. In case of using laser to disc decomperssion,small amount of nucleus pulposus evaporates.

FAQ
1: WHAT IS PLDD?
The pldd (percutaneous laser disc decompression) is a not-surgical technique but truly minimal invasive interventional procedure for the treatment of a 70% of the disc hernia and 90% of the disc protrusions (these are small disc hernia that sometimes are very painful and do not respond to the most conservative therapies as pain killers, cortisonic and physical therapies and so on).
2: HOW DOES THE PLDD WORK?
It uses local anesthesia, a tiny needle and a laser optical fiber. It is practicated into the operating room with the patient in the lateral position or prone (for lumbar disk) or supin (for cervical). Firstly the local anesthesia in an exact point of the back (if lumbar) or of the neck (if cervical) is done, then a tiny needle is inserted through the skin and muscles and this, under radiological control, reaches the center of the disc (called nucleus pulposus). At this point the laser optical fiber is inserted inside the tiny needle and i start to delivery the laser energy (heat) that vaporizes a very small amount of the nucleus pulposus.
This determines a decrease of 50-60% of the intra discal pressure and therefore also the pressure that disc hernia or protrusion exercises on the nerve root (cause of pain).
