First U.S. Cases Using One-Step-Insertion of Pedicle 'Smart Screws'

Pedicle screw-based fusion has become the gold standard for treating spine instabilities and deformities.

SpineGuard, a company that develops and markets disposable medical devices to make spine surgery safer, announced the first cases in the USA using the one-step-insertion of pedicle “smart screws” guided by DSG (Dynamic Surgical Guidance) technology. The surgeries were performed successfully by eminent surgeons throughout the USA.
Thomas Freeman, Professor of Neurosurgery, Tampa, Fla., said: “I knew immediately where the trajectory of the screw was going, even without fluoroscopy. Rather than use five steps to put a screw into the spine, only one step was needed. I could redirect it easily if needed.”
“The DSG technology will change the way spine surgery is performed. It will allow us to place spinal instrumentation faster, safer and with greater accuracy minimizing the risks to our patients,” said Victor Hayes, MD, Orthopedic Surgeon, Trinity Spine Center, Tampa, Fla.
“Integrating the Dynamic Surgical Guidance technology with pedicle screws will greatly optimize the workflow and accuracy, and reduce radiation exposure for surgeons in both the traditional and MIS surgical settings. Not only will the ‘smart screw’ allow for active real-time guidance and breach-avoidance through the pedicle, but it will also provide unprecedented feedback and confidence in the ultimate fixation of the screw itself,” said Larry Khoo, MD, neurosurgeon at The Spine Clinic, Los Angeles, Calif.
“The procedures that we have performed with the self-guiding ‘Smart Screw’ technology have advanced the safety of spinal surgery exponentially by reducing the probability of nerve and spinal cord injury and reducing radiation exposure to patients and hospital staff,” added Farhan Siddiqi, MD, Assistant Professor, University of South Florida, Trinity Spine Center, Florida Advanced Spine, Sports, and Trauma Centers.
John I. Williams, MD, SpineONE, a division of Ortho NorthEast, Ft. Wayne, Ind., concluded: “One-step technology is something that is being explored by multiple implant manufacturers right now.... this ‘smart screw’ with DSG technology is simply going to remove several steps in the process of applying spinal instrumentation.”
For SpineGuard and Zavation, who announced their co-development partnership in early 2015, these successful first surgeries performed after obtaining 510(k) clearance from the U.S. Food and Drug Administration (FDA) are an essential milestone in preparation for the commercial launch of the Zavation pedicle screw instrumentation that integrates the DSG technology.
Pierre Jérôme, CEO and co-founder of SpineGuard, said: “These surgeries further validate the clinical utility of embedding our DSG technology into the vertebral implant itself, thus enabling its insertion without any preliminary step. We are steadfast in the concept that DSG technology will further secure and simplify the most commonly performed instrumented spine procedure, fusion, while optimizing its cost to the hospital with an ‘integrated guidance’ approach.”
Jeffrey Johnson, CEO and founder of Zavation, added: "Early surgery results with our Z-Direct Screw combined with the DSG technology have been very successful. The single-step technology allows surgeons to use less fluoroscopy and reduce surgery times with excellent screw placement.”
Pedicle screw-based fusion has become the gold standard for treating spine instabilities and deformities. The U.S. spine industry is estimated to have grown 5% between 2015 and 2016 to $7.8 billion in sales to US hospitals1. This is the highest year-to-year growth in this market since 2010, and reflects the growth in specific sub-segments of the spine market. The U.S. market for spinal implants and devices used in spinal surgery now exceed both the size and growth of the US hip and knee market which was estimated to be $7.5 billion in 2015, up 2.5% from 2014.
