Spinal canal stenosis is caused when the component at the central part of a compressed intervertebral disc (part of a layer called the annulus fibrosus) cracks, causing the disc to protrude and the protruding part (herniated disc) to narrow the spinal canal.
Lumbar spinal canal stenosis does not cause severe back pain, and there are few symptoms when the patient is at rest, but when standing or walking with a straight back, numbness, and pain in the thighs and below the knees may occur, making it difficult to walk. However, if you bend over or sit down a little, the numbness and pain will be reduced.
Conventional surgical methods relieve symptoms by removing the herniated disc and immobilizing the destabilized vertebrae, but since the cracks in the disc have not been repaired, there is some possibility that the disc will herniate again.
The Cellgel method used at our clinic injects an implant that fills the cracks in the intervertebral disc, which then forms a gel that replaces the cracks, thus providing a fundamental treatment.
