The approval has been granted to market the system using either a two-incision or a single-incision technique.

SImmetry system has been developed to carry out a minimally invasive procedure for conditions, including sacroiliac joint disruptions and degenerative sacroiliitis.

St. Augustine Flagler Brain and Spine Institute Dr David Greenwald said: "In the operating room, surgeons need as many options as possible to effectively treat each individual.

"This new SImmetry technique allows me to offer patients a single, one-inch incision and to adapt the surgery to their individual anatomy and condition."

The firm is also currently carrying out the US multicenter clinical study of the Glyder Facet Restoration Device, a non-fusion, minimally invasive technology intended to provide relief from lumbar facet pain.
