Nexus Spine Launches PressON Posterior Lumbar Fixation System

Nexus Spine has announced full launch of its PressON posterior lumbar fixation system.
 
PressON contains rods that press onto pedicle screws instead of attaching to set screws. The design is about one-fourth the size of traditional systems, eliminates possible set screw loosening, and allows intra-operative patient-specific rod construction.
 
It also uses flexible bores stretched over pedicle screw heads during implantation. The resulting elastic interference fit between screw and rod doesn’t use traditional set screws, which can loosen during implantation and post-op.
 
Thomas Sweeney, II, MD, Ph.D., the surgeon designer of the system, commented to the press, “There hasn’t been meaningful innovation in non-deformity posterior fixation technologies in a very long time. PressON is unlike anything else on the market in the way that the components are connected. Not only does it result in a construct that is smaller, stronger, and faster to implant, but it is also unique in its ability to create patient-specific multilevel rods intraoperatively. As a result, it eliminates the need for rod bending and the pain associated with improperly bent rods and rod creep. PressON is uniquely poised to disrupt the posterior lumbar fixation market that has long been mired by a lack of differentiation.”
 
“Our expertise in compliant mechanism engineering allows us to do some really unique things,” added David Hawkes, President of Nexus Spine. “The ability to secure PressON™ rods through elastic interference rather than using set screws is certainly a paradigm shift. We are in the process of shining a light on the incidence and harmful effects of set screw loosening through clinical and benchtop research. We look forward to sharing the results of these studies soon.”
