Distinctive elastic interference know-how solves set screw loosening and eliminates rod bending
August 23, 2022
SALT LAKE CITY–(BUSINESS WIRE)–Nexus Backbone, a developer of biomechanically-advanced options for spinal pathologies, at present introduced the total industrial launch of its PressON™ posterior lumbar fixation system. PressON™ options rods that press onto pedicle screws slightly than connect utilizing set screws. This novel design is roughly one quarter the scale of conventional techniques, is quicker to implant,1 is biomechanically stronger,2 eliminates the potential for set screw loosening, and permits for intraoperative building of patient-specific rods. This full market launch provides to the corporate’s rising compliant mechanism-based portfolio, together with its line of versatile Tranquil™ titanium interbody fusion units, and follows a prolonged validation section of refinements and system enhancements.
Nexus’s use of compliant mechanism know-how permits for the creation of novel designs that behave in essentially new methods to resolve unmet medical wants. Compliant mechanisms operate by bending slightly than sliding. For instance, PressON™ incorporates versatile bores which are stretched over pedicle screw heads throughout implantation. The ensuing elastic interference match between screw and rod doesn’t use conventional set screws, which have been proven to loosen throughout implantation and postoperatively.3,4
Thomas Sweeney, II, MD, PhD, the surgeon designer of the system, commented, “There hasn’t been significant innovation in non-deformity posterior fixation applied sciences in a really very long time. PressON™ is in contrast to anything available on the market in the way in which that the parts are related. Not solely does it end in a assemble that’s smaller, stronger, and sooner to implant, however it is usually distinctive in its capability to create patient-specific multilevel rods intraoperatively. Consequently, it eliminates the necessity for rod bending and the ache related to improperly bent rods and rod creep. PressON™ is uniquely poised to disrupt the posterior lumbar fixation market that has lengthy been mired by a scarcity of differentiation.”
“Our experience in compliant mechanism engineering permits us to do some actually distinctive issues,” commented David Hawkes, President of Nexus Backbone. “The flexibility to safe PressON™ rods by elastic interference slightly than utilizing set screws is actually a paradigm shift. We’re within the technique of shining a light-weight on the incidence and dangerous results4 of set screw loosening by medical and benchtop analysis. We stay up for sharing the outcomes of those research quickly.”
About Compliant Mechanisms
Compliant mechanisms mimic nature by offering movement and power transmission by bending slightly than from conventional sliding joints. This breakthrough permits bio-friendly supplies similar to titanium to operate extra like human tissues, on the macro and microscopic ranges. This method makes use of trendy mathematical modeling, 3D finite elemental evaluation, and 3D printing to drastically enhance the way in which that spinal implants carry out. Nexus compliant mechanism-based units have been implanted in sufferers since 2015 with the purpose of attaining sooner therapeutic with much less ache and at a decrease price.
About PressON™ Spinal Fixation System
PressON™ is a singular pedicle screw-based spinal fixation system that options rods which are elastically pressed on to screw heads as an alternative of tightened utilizing conventional set screws, that are susceptible to loosening and subsequent assemble instability.4 PressON™ employs compliant mechanism know-how to match the affected person’s particular anatomical wants, eliminating spinal rod-bending and different painful persuasion strategies presently utilized in spinal surgical procedures. Moreover, PressON™ is considerably sooner1 and simpler to implant and is roughly one quarter the quantity of aggressive units, thus reducing incision size and comfortable tissue irritation.
About Tranquil™ Interbody Fusion Know-how
Tranquil™ is a versatile interbody fusion machine product of titanium that’s formed and engineered utilizing compliant mechanism principals to behave like spinal trabecular bone by mimicking its stiffness, leading to a tool that’s 1/10th the stiffness of conventional aggressive interbody fusion implants. Tranquil™ is on the market in cervical, ALIF, PLIF, TLIF, steerable TLIF, and DLIF configurations.
About Nexus Backbone
Nexus Backbone develops industry-leading spinal implants by leveraging our novel compliant mechanism engineering experience. Our modern and evidence-based method continues to advance the usual of surgical applied sciences by a rigorous concentrate on enhancing medical outcomes whereas being simpler to implant.
