ABSTRACT

The development of pedicle screw instrumentation systems has revolutionized spine surgery. From a biomechanical perspective, pedicle screws provide the greatest degree of spinal stabilization among all spinal implants. Pedicle screws, attached to rods linked by crossmembers, provide rigid control of vertebral body motion in all three spatial dimensions. This characteristic provides substantial advantages to the spinal surgeon for treatment of numerous disorders. Pedicle screws offer distinct advantages in the treatment of tumors, trauma, and deformity of the lumbar spine. They can be applied in nearly any situation involving instability of the lumbar spine.
