S MIS Cannulated Pedicle Screw System

Patented Interlocking Thread Design

The S4® MIS Cannulated Pedicle Screw System is designed and engineered to maximize stability of construct and provide easy implantation. The extended tabs increase rod capture range of motion and the patented interlocking thread design minimizes splaying of the screw body. The S4 efficiently transfers energy throughout the construct, maximizing rod grip while maintaining an exceptionally small implant volume. 

S4 offers access to a unique set of specialty instruments to reduce spondylolisthesis and fractures.
