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.
