Laser treatment for PLDD
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.
