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.

PLDD is the minimally-invasive medical procedure 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 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 procedure appear to be now days a safe and valid alternative to the microsurgery, with a rate of success of 80%, particularly under CT-Scan guidance, in order to visualize the nerve root and also apply energy on several points of disc herniation. This permits to have a shrinking concentrated in a bigger area, realizing a minimal invasiveness on the spine to be treated, and avoiding the potential complications related to the microdiscectomy (recurrence rate of more than 8-15%, peridural scar in more than 6-10%, dural sac tear, bleeding, iatrogenic microinstability), and does not preclude traditional surgery, if needed.

 

Advantages Of PLDD with HEAGER Adolf Laser Treatment

  • It's minimally invasive, hospitalization is unnecessary, patients get off the table with just a small adhesive bandage and return home for 24 hours of bed rest. Then patients begin progressive ambulation, walking up to a mile. Most return to work in four to five days.
  • Highly effective if correctly prescribed
  • Processed under local, not general anesthesia
  • Safe and fast surgical technique, No cutting, No scarring, Since only a tiny amount of disc is vaporized, there is no subsequent spinal instability. Different from open lumbar disc surgery, there is no damage to the back muscle, no bone removal or large skin incision.
  • It's applicable to patients who are at higher risk to open discectomy such as those with diabetes, heart disease, decreased liver and kidney functions etc.

Open Discectomy PLDD

This surgery will be performed under general or spinal anesthesia depending on the surgeon's or the patient's preferences. The patients will be positioned prone and the affected disc level is verified with fluoroscopy. A small midline incision (2–3 cm) will be made and the paravertebral muscles will be dissected unilaterally. Laminotomy will be performed when deemed necessary. In order to decompress the nerve root, the herniated disc will be removed as much as possible through a unilateral transflaval approach. The wound will be closed in layers with a suction drain when necessary. Patients will be operated with loupe magnification or microscope depending on the surgeon's preference. The participating surgeons have large experience in the technique. A standardized case record form (CRF) will register the surgeon's findings and will be sent to the data center. Patients will be admitted to hospital for 2–7 days depending on the usual care.

The patient will be instructed to take a prone position on the table of the CT-scan. After placing sterile drapes the level of treatment is identified by a scan. The needle entry point is anesthetized by local lidocaine injection no deeper than the facet joint. Subsequently the 18G needle is placed centrally in the nucleus pulposus, and parallel to the endplates by means of a posterolateral approach. Through the needle, a glass fiber is placed in the disc, enabling the application of laser energy (980 nm, 7 W, 0,6 s pulses, interval 1 second). After a total energy of 1500 J is delivered (2000 J for level L4-5), the PLDD procedure is finished. A control CT scan is performed to assess gas formation in the disc space. After the treatment the patient is allowed to drink tea or coffee and is observed for 15 minutes before he/she can return home.
