Part of the Johnson & Johnson Family of Companies, DePuy Synthes Spine has chosen this week’s North American Spine Society meeting at which to launch the SYNFIX® Evolution System, a new implant for stand-alone Anterior Lumbar Interbody Fusion (ALIF).
The use of stand-alone ALIF, in which the spine is accessed through the abdomen, is growing at a rate of three percent each year globally, a trend that is thought to be driven by reduced complication rates compared to fusion surgery performed through the patient’s back.
DePuy Synthes Spine’s SYNFIX Evolution System delivers biomechanical stability to promote fusion and restore function, coupled with instrumentation designed to optimize surgical workflow.
SYNFIX comprises a PEEK spacer, coupled with a titanium zero-profile plate and four divergent locking screws, which create a wedge of bone that helps anchor the implant during the healing process. The range of implant options allows the surgeon to accommodate varying patient anatomies and restores spine balance. The SYNFIX Evolution System increases surgical efficiency by reducing the number of instruments and increasing screw insertion speed. The SYNFIX Evolution System design team engineered an innovative thread lock sleeve to capture the screw to the screwdriver, preventing the screw from becoming disengaged during surgery.
Multiple studies of SYNFIX® Implant technology show that it provides superior biomechanical stability compared to other stand-alone ALIF implants and equivalent biomechanical stability relative to lumbar fusion performed through the back.
“Biomechanical stability in an implant is paramount,” said Alexandre Rasouli, MD, Cedars-Sinai Medical Center. “It is the difference between a single stage surgery and a more involved multi-stage surgery that can increase complications and drive up costs.”
“DePuy Synthes has been a leader in providing solutions for stand-alone ALIF procedures for more than a decade, and we are committed to investing in this market to ensure we continue to meet the needs of our customers and patients,” said Dan Wildman, Platform Leader, DePuy Synthes Spine. “The launch of the SYNFIX Evolution System shows that we continue to respond to our customers by developing a product that is easy to use while helping improve operating room efficiency.”
Low profile plate for Spinal Fusion in the Neck
Also at NASS, DePuy Synthes Spine is launching its ZERO-P NATURAL™ Plate to help maintain stability and support bone growth in spinal fusion procedures in the neck. The ZERO-P NATURAL Plate is designed for use with the CC Natural spacer, an allograft spacer that offers structural support and fusion potential.
Allograft interbody spacers are considered a primary choice for ACDF, representing 50 percent of all implanted cervical fusions. These spacers, including the CC Natural allograft spacer, work as a bridge to allow the natural bone to grow through the surface to support fusion.
The ZERO-P NATURAL Plate is the newest addition to the DePuy Synthes zero-profile family of products, which do not protrude past the anterior wall of the vertebral body, limiting the risk of damage to vessels and adjacent soft tissue. These plates are designed to prevent contact with adjacent levels. Cervical plates placed near adjacent level discs may contribute to bone formation near or around the adjacent level.
The anterior plate and CC Natural allograft spacer are assembled together outside of the operating field, allowing for simultaneous insertion into the disc space during anterior cervical discectomy fusion (ACDF) procedures. The ZERO-P NATURAL Plate is anchored by four locking screws, which form a rigid bone wedge for stability.
“Compared to ACDF with a traditional plate and allograft, there is no need to expose the vertebral bodies beyond their endplates, resect anterior osteophytes, or remodel the anterior surface of the vertebral bodies,” said Peyman Pakzaban, MD, FAANS, Houston MicroNeurosurgery.** “The insertion of a pre-fabricated allograft and the zero-profile plate is performed in one combined step.”
Dan Wildman, Platform Leader, DePuy Synthes Spine added, “DePuy Synthes has a strong track record in providing solutions that help improve patient outcomes in cervical spine fusion, and the ZERO-P NATURAL Plate is the latest example of our focus on innovation that serves customers and patients while promoting surgical efficiency.”
