In the Harley Street Spine Clinic we are developing and auditing our use of Gelstix as a means of augmenting the degenerating disc and correcting the internal acidity and metabolism within the disc. Uniquely we are combining this with Transforaminal Endoscopic Lumbar Decompression and Foraminoplasty. This allows us to treat the painful nerves and preserve the integrity of the disc wall and so insert the Gelstix to inhibit the on-going degeneration within the disc. We also use the Gelstix to treat ailing discs above or below the key painful disc level where appropriate.

Our current outcomes have been very encouraging.

We are working with the company to combine the use of Gelstix with Laser Disc Decompression and our Stem Cell Technology in the future.

If you are interested in pursuing this modern treatment then please read the associated literature for your further information. You will see from this information that we have been able to expand the patient selection envelope to extend this treatment to patients with more advanced Degenerate Disc Disease.

General Description:

  • The GelStix™ Nucleus Augmentation Device system is intended as a treatment for degenerative disc disease. The device may be implanted through a posterolateral discography approach.
  • The GelStix™ device is made of a biocompatible, biostable hydrogel, and is offered in various gauge diameters and 25, 30 and 35 mm lengths.
  • Package Contains: GelStix™ in Delivery Cartridge (3), 18 Gauge Spinal Needle (1), and a Desiccant Pack to maintain low moisture. The supplied needles are designed to fit with GelStix™. Use to assure proper function.

This is a new treatment for painful degenerate discs that avoids conventional surgery. The treatment involves inserting 1-3 hydrogel stick implants into the centre of the damaged disc. The implant absorbs water very quickly swelling to three times its original size, thereby ‘bulking up’ the worn disc. It retains shape under pressure and is very resilient to deformation. This allows the material to absorb impact loading and acts more like a normal intervertebral disc. The polymer reduces the acidity of the disc tissue allowing existing, metabolically suppressed disc cells to recover.
