Effect of Surgical Tightening Torque on the Pull-Out Strength of Screws in Vertebral Body Tethering

2025-09-05

Abstract excerpt

<h4>Background: </h4> /Objectives: Screw loosening and vertebral fractures remain common after vertebral body tethering (VBT). Because tightening torque sets screw preload, its biomechanical effect warrants explicit modeling. In this paper, a Finite Element (FE) model, supported by ex-vivo porcine vertebrae tests, was developed and validated that incorporates torque-induced pre-tension to quantify vertebral stress...
