SCREWFIX is a useful instrument in the bone augmentation stabilization using cannulated and/or fenestrated pedicle screw. Thanks to SCREWFIX, the PMMA is injected through the screw for better screw fixation in osteoporotic conditions.
SURGICAL TECHNIQUE:
• Access to the bone
• Place the screw
• Set up the PMMA
• Insert PMMA through the SCREWFIX up the distal part
• Insert SCREWFIX through the screw
• Inject PMMA through the cannula with the pusher
BENEFITS:
• Controlled distribution of the PMMA
• Optimal fitting with the screw
• Enhanced bone-screw interface
• Compatible with low, medium and high viscosity cement
DIFFERENT TYPES OF TIP ARE AVAILABLE:
• Straight tip: same diameter for the entire length of the device
• Variable diameter tip for easier insertion through the screw
• Variable diameter tip with a joint that allows the cannula to be locked into the screw
• Lateral windowed tip for precise and directional cement injection
STRAIGHT TIP
VARIABLE TIP WITH JOINT
