Explanation
|
|
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.
