Minimizing Invasiveness by Percutaneous Stenoscopic Lumbar Decompression (PSLD) for Lumbar Spinal Canal Stenosis.
This is the title of a Japanese study which is published recently. “It was possible to use instruments similar to open surgery, and the drilling of spinal laminar bone, resection of ligamentum flavum, removal of intervertebral disc, etc., could be performed smoothly. It is important that spinal surgery for the patient is minimally complicated and invasive; moreover, it is desirable to return to home early.”
