Study Shows Positive Results of Spinal Resources’ Bezier Parametric Curve Transition Rods 

Spinal Resources released new study results that demonstrate its Bezier Parametric Curve Transition Rods, which were shown to offer a smoother load transition, reduced stress on proximal segments, and reduced disc stress on the UIV. This ability to address the overall stiffness leads to a global construct benefit while still providing necessary correction.

The Bezier Parametric Curve Transition Rods are a customizable patient-matched platform that uses a precision manufacturing process to provide spinal 3D correction capabilities while minimizing proximal construct stresses, along with an overall reduction in construct stiffness. 

These Rods achieve stiffness adjustment by varying the rod’s section diameter along specific lengths and segment orders. This is accomplished through the strategic placement of Bezier Zones throughout the rod, enabling precise control over stiffness distribution.

The Rods were designed for excessive stiffness and Proximal Junctional Kyphosis (PJK). 

Surgeon and researcher Dr. Zack Temple (Mayfield Clinic), said, “The Bezier rod portfolio offers a unique solution for deformity surgeons who appreciate a tailored approach for complex patients. Despite the rapid evolution of our field, with respect to biomechanics and the importance of geometric parameters, the current industry players provide surprisingly limited options, exposing an Achilles heel for deformity operations. With a wide range of stiffness combinations in the preservation of strength across transitional zones, the Bezier rod portfolio represents a major step in the evolution of rod customization to address overall construct stiffness and not just a proximal failure point.”

Bezier rods offer surgeons control and may offer superior performance in terms of reducing the risk of PJK compared to conventional rod designs.

Bernie Bedor, President and Chief Executive Officer of Spinal Resources Inc., stated, “The Bezier technology is also applicable to degenerative applications, providing a potential benefit by reducing the risk of high stress or disease progression in adjacent segments above the lumbar spine. Our goal is to treat these matters globally by addressing the overall construct to yield a better outcome locally.”

Adult and Pediatric Spine Surgeon Dr. Amit Jain (John’s Hopkins) commented, “As someone who takes care of pediatric and adult patients with spinal problems, I am always thinking about ways to reduce stresses at adjacent levels. This is particularly important in the pediatric population, as kids have a lifetime ahead. Thus, it’s important to be conscientious in their care. The Bezier rod caught my attention as it allows mitigation of these stresses throughout the overall construct leading to desired results at ends of the construct.”
