Anterior Lumbar Fixation System Simplifies Spinal Fusion

An innovative surgical device uses a one-step locking mechanism that simplifies stand-alone intervertebral fusion surgery.

The Logic system is indicated for stand-alone intervertebral body fusion in patients with degenerative disc disease, at one or two contiguous levels of the lumbosacral spine (L2-S1). Each implant is designed with a large central window for optimum autograft bone placement, with size offerings range 10–20 mm in height, and all devices having an anatomically-shaped lordotic angle that matches the convex curvature of the vertebral endplates. The devices are implanted into the intervertebral space and are then stabilized with three screws placed through the device into the vertebrae to facilitate fusion.

The Logic system is made of PEEK-OPTIMA polymer, a versatile polymeric biomaterial with strength and durability characteristics that provides a combination of high strength, stiffness and toughness, and proven biocompatibility. Another feature is inherent radiolucency, which does not generate image artifacts that interfere with the assessment of the healing site via X-ray, computerized tomography (CT), or magnetic resonance imaging (MRI) imaging modalities. The Logic system is a product of Binder Biomedical (Miami, FL, USA); PEEK-OPTIMA is manufactured by Invibio Biomaterial Solutions (West Conshohocken, PA, USA).

“We are excited to bring such a streamlined device to market,” said Lawrence Binder, President of Binder Biomedical. “Our design team has done a great job putting together such a comprehensive system, ensuring that it can be tailored to any surgeon's preferred surgical technique."

“Rather than being content with the industry standard, we have created a truly innovative system that reflects our lengthy collective experience as surgeons and engineers,” added design team member Peter Whang, MD, an associate professor in the department of orthopedics at Yale University School of Medicine (New Haven, CT, USA). “Together, we have created a world-class system that meets all of our needs while maintaining ease of use.”

Interbody devices are designed to replace the intervertebral disc of the spine, enhancing stability in the region while the spine fuses. Over time, the packed bone graft material is gradually replaced by natural bone. The fusion procedure typically uses a posterior fixation device to the associated level, since the surgeons will implant interbody devices from an anterior approach and flip the patient over to implant a posterior pedicle screw device. This combination increases fusion success.
