Spinal Implant Restores Function to the Spine

A vertebral body replacement (VBR) system restores mechanical and neurologic function by readjusting vertebral position until bone fusion occurs.

The PEEK Box system is manufactured from polyetheretherketone (PEEK) with Tantalum markers, and comes in a variety of different shapes. The implants are intended to be used in pairs, and are connected via internal supplemental spinal fixation systems such pedicle screws. Proud angled tooth design has been implemented on superior and inferior surfaces to resist migration, and a bullet-shaped tip has been designed to assist in distraction. The system has both parallel and lordotic-shaped implants with large central windows for placement of bone graft.

The system is indicated for use in the thoracolumbar spine (T1-L5) area to replace a collapsed, damaged, or unstable vertebral body resected, or excised during partial and total vertebrectomy procedures due to tumor or trauma. The system is designed to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body. The PEEK Box system is a product of Innovasis (Salt Lake City, UT, USA), and has been approved as a VBR by the U.S. Food and Drug Administration (FDA), after previously being cleared as a cement restrictor.

"This is good news for our company as we strive to be a recognized leader in the global spinal business by building intense customer loyalty and improving our products,” said Martin Crous, Ph.D., vice president of sales and marketing of Innovasis.

Polyetheretherketone (PEEK) is a material with an elasticity module (GPA) that is the closest to cancellous bone, when compared to cortical bone, titanium, or stainless steel implants.
