PLDD means that under the guidance of C-arm X-ray or CT, 16G or 18G puncture needle is inserted into the diseased cervical/lumbar intervertebral disc, 200-800μm optical fiber is introduced through the puncture needle, and then laser treatment system is started to emit laser to vaporize part of the nucleus pulposus of the intervertebral disc, thus reducing the pressure in the intervertebral disc.
The treatment process uses a thin optical fiber to emit pulsed lasers. Percutaneous laser disc decompression uses laser energy to hollow the diseased nucleus pulposus, reduce the pressure in the intervertebral disc, and relieve and eliminate the compression on the sciatic nerve or vertebral artery nerve.
Lumbar disc herniation is a frequently-occurring and common disease in clinical practice, and it is the most common cause of low back and leg pain. The disease mostly occurs in young adults, and part of it occurs in the elderly. The patient suffers a lot. In severe cases, it can cause paraplegia, which can have a great impact on the life, work and labor of the patient.
Percutaneous laser disc decompression (PLDD) is a procedure in which a surgical fiber probe is inserted into the disc space and the laser energy emitted by the fiber is applied to vaporize and ablate the nucleus pulposus to achieve decompression and neuromodulation and thus pain relief. It is a minimally invasive surgery with significant clinical advantages and falls under the category of percutaneous intervertebral surgery.
