Bone density optimized pedicle screw insertion
Frontiers in Bioengineering and Biotechnology, 2023 Background: Spinal fusion is the most common surgical treatment for the management of degenerative spinal disease. However, complications such as screw loosening lead to painful pseudoarthrosis, and are a common reason for revision. Optimization of screw trajectories to increase implant resistance to mechanical loading is essential.
