The Cortical Screw is the latest addition to Zavation’s portfolio. The cortical screw is designed to achieve greater cortical bone purchase with a smaller midline incision when using Cortical Bone Trajectory (CBT). It comes in a variety of sizes to provide an optimized fit for each patient. It also includes a self-tapping feature on both sides of the tip and a 30 degree variable head angulation. This optimized fit allows for enhancement of structural stability while the thread design maximizes screw purchase. Standard and reduction screw options are offered and the reduction screw has a “break-off” tab available.
Dr. Graham Calvert, Orthopedic Spine Surgeon at Mississippi Sports Medicine, stated, “I am very excited about the new cortical screw technology from Zavation Medical Products. With 3 zones of variable thread pitch it is tailor-made for the cortical trajectory. The system is also extremely versatile with 4.5, 5.0, and 5.5mm diameter offerings. Overall it is the most compact, durable, and easy to implant cortical system on the market. I have been utilizing for over a year now with one hundred plus cases and have had no hardware failure.”
The Zavation Spinal System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of thoracic, lumbar, and sacral spine: degenerative disc disease (DDD) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenosis; tumor; pseudoarthrosis; and failed previous fusion.
