Retentive head design immediately keeps the rod in position : faciltates alignment and prevents rod rejections by soft tissues.
Two different types of threads, each specifically adapted to a given environment : proximally, a cylindrical section ensures load bearing capabilities and optimum pedicle filling, distally a cylindrical pitch over a conical section provides good retention in cancellous bones.
Available with perforated screws in 6.5mm diameter for minimal invasive insertion and/or better precision in screw positioning, avoiding misdirection.
The 60° range of motion ensures comfortable adjustments in all reduction situations. In addition, the screw can be locked in a given configuration via its releasable polyaxial lock that facilitates reduction, distraction, compression and derotation by providing direct action on the vertebrae.
Quarter turn locking
Optimally lock the nut on the screw within a 90° angle. Lock the rod firmly with minimal effort.
The numerous features make this pedicular screw fixation device for thoracic and lumbo-sacral fixation unique:
Original thread shape: double thread for a faster insertion, dual shape, cortical on it's proximal part to fill the pedicule and cancellous progressively deeper thread for a better anchoring in the cancellous vertebral body, for a better resistance to pull out strengths.
Polyaxial-monoaxial on demand : simply locking the screw heads in ideal position, allowing to act directly on vertebrae during the reduction maneuvers.
The rod is caught inside the screw head by a simple pressure.
The fixation is made by a quarter turn quick locking nut.
The screw are available perforated to be inserted through guide wire in minimal invasive approaches.
Material : The biocompatibility and
mechanical properties of titanium
ensures high strength and excellent
durability even in the most demanding
Instruments : Compatible with minimally invasive procedures, all instruments are designed to be operated with guide wires.
