Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet
