Biomechanical effects of screw loosening after lumbar PEEK rod and titanium rod fixation: a finite element analysis
The PEEK rod fixation system demonstrated superior stress distribution, reducing stress concentration risks and improving stability while minimizing screw loosening rates. In contrast, the titanium rod system offers advantages in scenarios requiring high rigidity, potentially making it more suitable for patients with greater stability needs.
