In Space is an interspinous spacer, intended to stop segmental extension and to distract the interspinous space e.g. for dynamic lumbar stenosis. It is implanted through a percutaneous, tissue preserving approach.
Benefits:
- Percutaneous lateral approach;No stripping of the paraspinal muscle
- Tissue sparing procedure:Stabilizing anatomical structures are preserved:
-Supraspinous ligament is left intact-Interspinous ligament is only pierced to the size of the implant
-No bone needs to be trimmed to facilitate the insertion of the implant
- In-Situ deployment of the anchorage:When turning the screw (1), the implant closes and the wings (2) are deployed along the spinous processes
- Intrinsic stability:
-The wings prevent ventral and lateral migration of the implant
-The intact supraspinous ligament prevents dorsal displacementAbout Interspinous Devices
Interspinous spacers sometimes also called as Interspinous process decompression systems, are the devices implanted between vertebral spinous processes. These spacers are made up of a very strong but lightweight metal (titanium) which is biocompatible in the human body. These devices are imbedded in body to confine painful motion else enabling normal motion and to treat lumbar spinal stenosis, discogenic low-back pain, facet syndrome, disc herniations, and non-traumatic instability. Lumbar spinal stenosis is a thinning of the spinal canal in the lower back which causes compression on nerves and it is developed gradually with age. Radiology tests are used to confirm a diagnosis of moderate degenerative lumbar spinal stenosis. People with lumbar spinal stenosis experience pain but may also have weakness in their leg, lower back and buttocks, numbness, tingling.
The Interspinous spacer are implanted between those vertebrae in such a way that it prevents the patient from bending too far backward which causes pain by surgical procedure. The procedure is very small and sometimes patient can go home within a day.The increasing prevalence of spinal stenosis due to aging, arthritis, heredity and increased demand of surgical procedures that improved lifestyle and comfort will drive the Interspinous spacer market. The adoption of spacers are increasing due to low complication rate as compared to decompression and spinal fusion. The Interspinous spacers are widely used in geriatric population as per Medicare data due to old age patient are not comfortable with surgery due to their health conditions.
