PressON (spinal fixation implant)

2022: Spinal fixation device release

In August 2022, Nexus Spine announced the start of a full commercial launch of its PressON rear lumbar locking system, which is about a quarter smaller than traditional systems, with rods that are pressed against pedicular screws rather than fastened using mounting screws.

The company said in a press release that PressON implants faster, is biomechanically stronger, eliminates the possibility of loosening the mounting screws and allows intraoperative design of rods for a particular patient. It includes flexible holes stretched over the heads of pedicular screws during implantation, resulting in an elastic interference fit between the screw and the rod, without the use of traditional mounting screws, which are shown by practice to weaken during implantation and after surgery.

Dr. Thomas Sweeney, the surgeon who developed the system, said in a release that PressON is "unlike anything else on the market" regarding the way the components are connected. He added that due to the absence of the need to bend the rods and the pain associated with the improper bending of the rods and their sliding, the fixation system has "unique capabilities" to change the state of affairs in the market.

{{quote 'Our experience in developing interoperability mechanisms allows us to do really unique things,' said David Hawkes, president of Nexus Spine. The ability to fix PressON rods through elastic interference rather than by mounting screws is certainly a new step in the development of the paradigm. We are currently conducting clinical and laboratory studies to shed light on the prevalence and harmful effects of loosening the mounting screws. We look forward to sharing the findings of these studies^[1] }}
