Development and Testing of X-Ray Imaging-Enhanced Poly-L-Lactide Bone Screws. [PDF]
PLoS ONE, 2015 Nanosized iron oxide particles exhibit osteogenic and radiopaque properties. Thus, iron oxide (Fe3O4) nanoparticles were incorporated into a biodegradable polymer (poly-L-lactic acid, PLLA) to fabricate a composite bone screw.

Fatigue failure of cortical bone screws [PDF]
Journal of Biomechanics, 1983 An experimental study of the fatigue life of cortical bone screws under conditions which stimulated in vivo usage was performed. The two most important factors influencing fatigue life were axial screw tension (the force normal of the plate to bone) and the cyclic shearing load.

Developments in Modelling Bone Screwing [PDF]
Current Directions in Biomedical Engineering, 2020 Abstract INTRODUCTION: A torque-rotation model of the bone-screwing process has been proposed. Identification of model parameters using recorded data could potentially be used to determine the material properties of bone. These properties can then be used to recommend tightening torques to avoid over or under-tightening of bone screws ...
