Reno, Nevada, June 14, 2021 -- Dr. Edward Perry of Spine Nevada Minimally Invasive Spine Institute became the first surgeon in Nevada to use the INVICTUS OsseoScrew expandable pedicle screw system. The first screws were placed on 04/11/2021 at Renown Regional Medical Center. The screws were placed seamlessly and resulted in exceptional initial fixation. Dr. Perry is a board-certified neurological surgeon with fellowship-training in complex spine. He’s participating in ongoing research associated with the INVICTUS OsseoScrew expandable pedicle screw system to improve spine surgery outcomes.

After implantation, OsseoScrew is expanded to achieve increased screw fixation and reduced post-operative pullout in bone with poor density. OsseoScrew is clinically proven to increase pullout and holding strength, improving fixation in the bone-implant interface by 29% compared to conventional pedicle screws. It performs comparably to cemented screws without the risk associated with cement leakage. The OsseoScrew system is a positive step forward in the way surgeons address spinal instability in patients with weak bones.

“The OsseoScrew technology has been around for almost 15 years but with limited indications. The ability to significantly improve the pedicle screw pullout strength and reduce construct failures in all clinical indications, including osteoporotic patients and degenerative spine conditions with large constructs, could prove game-changing,” Dr. Perry emphasizes.

Because people are living longer, innovative solutions to address problems associated with aging are needed. ATEC Spine has sought to develop an improved way to stabilize the vertebral bone in the spine. Before creating the OsseoScrew system, the most common spine surgery technique was to anchor screws placed in the spine with acrylic polymers or glue such as polymethyl methacrylate (PMMA). The use of PMMA can result in longer surgery times, technical difficulties, and cement leakage. The neurosurgery team at Spine Nevada is an innovator in spine surgery and is involved in ongoing training in new technologies and minimally invasive surgical techniques for patient benefit.

About Spine Nevada 

Spine Nevada is a multi-disciplinary spine center of excellence located in northern Nevada with Reno, Sparks, and Carson City locations. The center takes a team approach to spine and musculoskeletal care. Spine Nevada’s Reno and Sparks locations are integrated spine care centers that combine non-surgical physical medicine physicians, fellowship-trained specialists in radiology, fellowship-trained spine neurosurgeons, and internal physical therapy gyms. The center provides all the necessary diagnostic testing and treatment in one place, eliminating the need for multiple referrals, delayed care, and confusion. 

The Spine Nevada neurosurgery team are innovators in spine surgery. The team has been performing minimally invasive spine surgery since 2002. They are the only surgeons in Reno to perform outpatient spine surgery. Spine Nevada neurosurgeons are the first in Reno to use the Globus ExcelsiusGPS. This revolutionary robotic navigation platform is the world’s first technology to combine a rigid robotic arm and full navigation capabilities into one adaptable platform for accurate trajectory alignment in spine surgery. The Spine Nevada neurosurgery team was also the first in the country to use the Augmedics xvision system at a community hospital. The xvision system allows the surgeon to visualize the patient’s 3D anatomy during surgery and to accurately navigate instruments and implants while looking directly at the patient versus a remote screen.
