If the doctor is fixing screws in the vertebrae, where will be the screw fixed?
Answer A) Pedicle
Pedicle screw fixation represents a landmark in the field of spinal surgery.
In view of the biomechanical advantages of pedicular fixation systems, which provide more tridimensional stability to the vertebral segment with a small area of instrumentation, even in the absence of posterior vertebral elements, and improves outcomes of spinal fusion, this modality of vertebral fixation has gained increasingly widespread acceptance.
Pedicle screw fixation is currently one of the most used modalities for internal thoracic and lumbar spine stabilization.
