A novel pedicle screw design to maximize screw-bone interface strength using finite element analysis and design of experiment techniques.

Study Design: Basic study.

Purpose: This study aimed to utilize finite element (FE) analysis and design of experiment (DoE) techniques to propose and optimize a novel pedicle screw design and compare its pull-out force with that of a control device.

Overview Of Literature: Pedicle screw-based fixation is the gold-standard treatment for spine diseases, particularly in fusion procedures.
