Pedicle Screw Systems: Strength and Stability in Reconstruction
Pedicle screws are fundamental devices in spinal stabilization. Their ability to anchor into strong vertebral bone allows surgeons to correct deformities, support fusion, and stabilize traumatic injuries.
Modern pedicle screws incorporate polyaxial heads, enabling angulation for rod placement. Self-tapping designs reduce the need for pre-drilling. Expandable screws offer added grip in osteoporotic bone.
The combination of pedicle screws with rods forms a rigid construct that supports alignment correction. Precision placement is enhanced by navigation and robotic tools, minimizing risk to neural structures.
Improved metallurgy and manufacturing have contributed to durability. Pedicle screw systems continue to evolve, supporting increasingly complex surgical goals.
