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

A Clinical Evaluation of Percutaneous Hydrodiscectomy

An independent clinical consultant reviewed all of the clinical data obtained from published literature, pending publications, and data not published on file with Hydrocision, for percutaneous hydrodiscectomy. Quality analysis was conducted using 5 levels of evidence, ranging from Level I to III with 3 subcategories in Level II, developed by the US Preventive Services Task Force 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 73–98.6%. 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.

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

This was a multi-center retrospective review published in the January, 2013 edition of the Internet Journal of Spine Surgery. Improvement in back pain and radiculopathy occurred in 94% of patients. The authors concluded that Percutaneous Hydrodiscetomy is a viable treatment option with minimal risk of complications for patients with radiculopathy secondary to subligamentous lumbar herniated nucleus pulposus and can be added to the non-surgical treatment algorithm in select 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 post-operatively, 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

A total of 15 patients underwent percutaneous Hydrodiscectomy without complications. Fourteen (93%) had an improvement in back pain and radiculophaty as evidenced by VAS and ODI scores.

Tissue Consumption Analysis Using the SpineJet MicroResector in a Cadaveric Study

Read further to learn about how the SpineJet MicroResector demonstrates predictable tissue consumption rates for nucleus removal of a broad range of tissue conditions and ages. In this cadaveric study, two disc specimens were chosen that represented the extremes likely to be encountered clinically for this procedure. One specimen was from a 39-year-old woman; her discs were healthy and well hydrated. The other disc specimens were from a 69-year-old man and were desiccated and somewhat degenerated. It was found that the MicroResector safely accessed a targeted area of the disc. The diminishing rate of consumption is attributed to the evacuation of nucleus in the targeted area.


Percutaneous Lumbar HydroDiscectoomy

Drs. Borshchenko, Baskov, and Migachev discuss their experience with Hydrodiscectomy to treat disc herniations and present the technique and clinical examples. When they followed up with patients, they found that MacNab criteria showed excellent and good results in 88% of patients treated with significant improvement in SF36 scores. These patients also communicated a decrease in radicular and back pain. Improvements were documented within the first hours after the procedure. They conclude that Hydrodiscectomy is a novel percutaneous technique for treating disc herniations and is effective for treating radicular pain.


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

This accepted abstract 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 Invasiave Percutaneous Hydrodiscectomy - Preliminary Report

The results of percutaneous lumbar Hydrodiscectomy were assessed in 97 patients using Visual Analog Scale (VAS), Oswestry Disability Index (ODI) and Macnab Criteria. Average follow-up time was 5.93. Authors Conclusions: Hydrodiscectomy is an effective minimally invasive percutaneous technique for disc herniation treatment. It is effective not only for radiculopathy but also for low back pain treatment. The surgical outcomes can be better predicted by herniation size and type than by patient age, gender or workers compensation status.
