What are transpedicular screws?
Transpedicular screws are devices used in spinal surgeries to stabilize the vertebrae.
Why use a porcine model for this study?
Porcine models closely resemble human anatomy, making them suitable for surgical evaluations.
What complications are associated with pedicle screws?
Common complications include loosening of the screws and failure of the fixation.
How long were the pigs monitored in the study?
The pigs were maintained for at least one week prior to the surgical intervention.
What is the significance of this research?
This research aims to improve the understanding of screw stability and enhance surgical outcomes.
