Lumbar spinal stenosis occurs when the spinal canal becomes narrow and compressed, putting pressure on the spinal cord and nerves, which in turn may yield low back and leg pain. An interspinous spacers, is a small implantable device used to treat lumbar spinal stenosis. It is inserted via a minimally-invasive outpatient procedure, with little to no recovery time, and can be done under local anesthesia or sedation. The interspinous spacer device provides ongoing support to maintain the separation between the vertebrae spinous processes, thereby helping to decompress the spinal canal and relieve pressure on the spinal cord and nerves. Interspinous spacers have been shown to be effective in reducing pain, improving function, and increasing mobility in patients suffering from lumbar spinal stenosis.
