Minimally-Invasive Lumbar Microdecompression
What is Minimally Invasive Lumbar Microdecompression?
This minimally invasive lumbar microdecompression procedure is used to remove overgrown vertebral bone and soft tissue to relieve the compression of nerve roots in the lumbar spine.
After anesthesia has been administered, the surgeon uses a portable x-ray machine to identify the diseased vertebral levels. Then, the surgeon makes the smallest possible incision in the skin directly above the target level.
A series of dilators of increasing size are carefully guided down through muscles and soft tissue. The surgeon slides a tubular retractor over the dilators and removes the dilators, creating a working channel that leaves muscle tissue intact. This working channel allows the surgeon to access the target vertebra and painful nerve root in a way that minimizes incisional pain and scarring of the muscles.
The surgeon may use a microscope or endoscope to direct surgical instruments through the working channel. Excess bone or ligament tissue is carefully removed from the space around the nerve root, relieving pressure and pain.
