HydroCision has announced that a multicentre study, published in the Internet Spine Journal, showed that its hydrodiscectomy system (SpineJet) was associated with a 94% improvement in back and leg pain

According to a company press release, HydroCision’s hydrodiscectomy procedure uses a high velocity water jet to quickly and effectively decompress herniated discs without the collateral thermal or mechanical trauma associated with other surgical modalities. This minimally invasive procedure can be performed through a needle-sized cannula thereby minimising patient postoperative pain and recovery time. Patients undergo local instead of general anaesthesia in an outpatient setting and are able to return home the same day with no more than a plaster on their back.


The study consisted of a retrospective analysis of 50 patients with a herniated disc who received the Hydrodiscectomy procedure after failing conservative treatment such as pain medications, physical therapy and epidural steroid injections.


“We are excited and encouraged about these study findings,” said Howard Donnelly, CEO adding that “one of our core strategic initiatives will be to continue to invest in US based research projects designed to further validate the clinical and economic value of HydroCision products for clinicians and their patients as well as government sponsored and private insurance companies.”
