6.0 Pedicle Screw Spinal Internal Fixation System

Impact of Screw Trajectory Techniques: Under osteoporotic conditions, screws utilizing modified cortical bone trajectories (even with diameters less than 6.0mm) may exhibit superior pull-out resistance and stability compared to conventional 6.0mm pedicle screws. This demonstrates that the fixation trajectory and quality of bone contact are sometimes more critical than simply increasing screw diameter.

Advances in Materials Science: Novel low-modulus titanium alloys are now employed for screws and connecting rods. Such systems deliver adequate stability while exhibiting reduced internal stresses and enhanced load-sharing capabilities, thereby mitigating the risk of fatigue fractures in internal fixation.
