Introducing the Bezier Parametric Curve Transition Rods. Our innovative transition rods are an integral part of a groundbreaking four-rod system housed in a single-screw tulip with a one-step locking cap.
These FDA-cleared, patented transition rods are expertly designed to provide enhanced flexibility without compromising on durability. They reduce material stresses and long-term risks associated with deformity and degenerative spinal surgeries, ultimately providing a more dynamic, patient-specific solution.
Experience a reduction in overall costs, and an increase in surgical outcomes with our Bezier Transition Rods. They are not just a component – they are the essence of the Swedge™ System’s commitment to revolutionizing spinal surgery.
This aims to provide a distinct perspective, emphasizing the transition rods’ pivotal role within the Swedge™ system and highlighting the overall value it brings to spinal surgeries.
Our Bezier Parametric Curved Transition Rods have a parametric curve between and within sections, eliminating the transition junctions typically found in stepped rods. This novel design contributes to lower material stresses and a reduction in contact pressure, stress shielding and micromotion.
Harnessing the power of AI, we can provide patient-matched, patient-specific rods to accommodate for bi-lateral inconsistencies as well as matching to dexa and houndtooth units leading to improved postoperative outcomes.
SRI prides itself on seamless integration. Our rods form part of SRI’s innovative system, enhancing surgical flexibility and compatibility.
We aim to lower long-term costs by the system’s ability to potentially minimize the risk of Proximal Junctional Kyphosis (PJK) and Adjacent Segment Disease (ASD), reducing the need for revision surgeries — further underscoring its economic advantage.
Anterior flexion of 1.5 degrees per screw was applied to create a constant curvature of each fixation rod. Flexion-produced material stresses were particularly high at the transition region (Middle) of the stepped rod. The transition regions in the tapered rod were 27.1% lower (Top)
Peak flexion stresses in the tapered rod transitions were reduced by 34% as compared to those at the stepped transition (Middle).
Contact pressures were drastically reduced with the 5.25-5.0-4.75mm gradually tapered rod (Top) as compared to that of the 6.35mm (1/4”) constant diameter rod (Bottom). At the midpoint, contact pressures were reduced by as much as 90%.
Proximal segment are solicited to a lesser extent with Bezier rods compared to their constant rod counterparts.
A sharp transition between T 10-T11 and T9-T10 is present with the conventional rod vs a smoother transition with the other rods.
Highest implant offload obtained with Bezier 5.5-5-4.75 scenario.
Implants loads are offloaded to a greater extent with Bezier Rods compared to their constant rod counterparts.
Comparable coronal deformity correction.
