The following studies provide scientific evidence supporting the value of HydroDiscectomy:

Clinical Outcomes of Patients Treated with Hydrodiscectomy for Radiculopathy Secondary to Lumbar Herniated Nucleus Pulposus

This multi-center, peer reviwed study appeared in the January, 2013 edition of The Internet Spine Journal. The study consisted of a retrospective analysis of 50 patients who received the Hydrodiscectomy procedure after failing conservative treatment such as pain medications, physical therapy, and epidural steriod enjections. The study demonstrated a 94% improvement in back and leg pain.

A Clinical Evaluation of Percutaneous Hydrodiscectomy

This report, developed by an independent research consultant, objectively evaluated 10 published and unpublished studies conducted to date on the Hydrodiscectomy procedure. Conclusion: The safety and effectiveness data for the percutaneous hydrodiscectomy studies are consistent across all data sources. There are no device related complications and success rates ranged from 73% to 98.6%. The high success rates combined with the positive safety profile associated with the use of the device are acceptable when weighed against the benefits to the patient. The reported clinical data support the use of the SpineJet Hydrodiscectomy System in the treatment of lumbar herniated nucleous pulposus in this select group of patients.

The Treatment of Lumbar Disc Herniation Through Percutaneous Hydrodiscectomy

In this article the authors evaluated percutaneous SpineJet HydroDiscectomy for the treatment of lumbar disc herniation in 69 patients. After 270 days, ninety-eight percent of the patients reported excellent or good results. The authors concluded that SpineJet percutaneous HydroDiscectomy does not affect the biomechanical stability of the spine and does not result in serious complications.

Minimally Invasive Percutaneous HydroDiscectomy: Preliminary Report

Read further to learn about the postoperative results of 13 patients who had a percutaneous HydroDiscectomy procedure. At approximately 5½ months follow-up the authors found that 6 patients had stopped pain medication entirely and 6 patients had reduced their pain medication to 1/3 of their preoperative dose. One patient reported a poor outcome, although this was a result of returning to work too early after the procedure to perform manual labor. The 12 patients who had good or excellent results reported that they would have the procedure done again, if needed, and would recommend this procedure to other patients.

Preliminary Results of Patients Treated with Percutaneous Hydrodiscectomy for Radiculopathy Secondary to Herniated Nucleus Pulposus

This abstract has been published in the American Society for Interventional Pain Physician's 4th Annual Abstract and Poster Session. It details the successful results of 15 patients who received Hydrodiscectomy after failed conservative treatment and concludes that 93% of them had improvement in back and leg pain.

Hydrodiscectomy - A Percutaneous Technique to Treat Radicular Pain from Contained Lateral Lumbar Disc Herniations

This case report was presented by Dr. Fred Gerges from St. Elizabeth’s Pain Center in Boston at the Annual Regional Anesthesia Acute Pain Medicine Meeting on May 2, 2013. The report details the successful outcome of the Hydrodiscectomy procedure on a 43 year old male patient, diagnosed with a contained herniated disc, that had not responded well to conservative therapy.

Minimally Invasive Percutaneous Hydrodiscectomy - Preliminary Report

The results of Hydrodiscectomy were assessed in 97 patients using various pain assessment methods. The average post-operative pain assessment period was 6 months. The results demonstrated 88% effectiveness in the study patients. Ninety Percent of the patient were able to return to work within two weeks of having the procedure with no reported complications.

Case Study: Hydrosurgical Decompression of a Large Lumbar Disc Herniation

This case report illustrates a successful short-term outcome and objective result following hydrosurgical decompression of a large lumbar disc herniation for chronic back and leg pain. HydroDiscectomy may be useful on larger herniations that cannot be effectively treated with other methods. The case report includes pre and post-operative MRI image findings.
