Spiral Radius 90D Spinal System
Uniquely engineered components in this spinal surgery system includes the following: a one-step, two-stage locking mechanism; a floating saddle for circumferential locking of the rod; and a defined locking position of the implant into its seat. Unlike similar spinal systems, Stryker’s provides a non-threaded wedgelock locking mechanism (eliminating a torque measuring device), and is designed to reduce the potential for false locking and cross-threading. This unique locking mechanism also increases the speed, ease, and reliability of connecting rods to screws.
Features & Benefits
Key advantages include:
- Floating saddle design: This unique design provides circumferential locking of the rod to the head of the screw.
- Defined locking position: The Spiral Radius 90D offers a well-defined locking position of the rod relative to the screw head to assure it’s fully seated.
- Non-threaded Wedgelock design: The 45-degree provisional and 90-degree final tightening of the non-threaded closure mechanism help fully seat the rod into the screw head and minimize an incidence of false locking.
- Low profile and small screw head diameter: The screw profile is one of the smallest of all major spinal systems. Small head diameter minimizes facet joint impingement and leaves more room for successful bone graft.
