PERLA® TL PS
POLYAXIAL PEDICLE SCREW
Double Rod Diameter Compatibility
The PERLA® TL screw head is compatible with both Ø5.5 and Ø6 rods, for versatility in treating a wide range of pathology.
Dual Core and Double Thread Screw
The Dual Core creates a constant external diameter with a variable thread depth. This allows a better adaptation to the vertebra anatomy and improved screw resistance and bone purchase: deeper threads for cancellous bone and shorter thread for cortical bone. The Double Thread allows for a faster insertion to a single thread screw, reducing fatigue.
Polyaxial and Friction Head
The 60° polyaxiality of the screw head allows to tolerate alignment discrepancies. Screw head friction is designed to keep the desired position.
All the instrumentation needed fits in only two boxes.
