Comparison of the bone response to xenogenic bone screws and metallic screws in canine femur [PDF]
Veterinární Medicína, 2014 The study compared the bone response to xenogenic screws and metallic screws of a similar design in a canine femur. The xenogenic bone screws and metallic bone screws were inserted into the femur diaphyses of dogs. Radiological and histological responses

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.

The influence of “kickstand” screws on the mechanical performance of a lateral distal femoral plate: a finite element analysis [PDF]
Bone & Joint ResearchAims: Lateral locked plating of distal femoral fractures is widely reported, yet there remains a 9% to 19% incidence of mechanical failure. Obliquely directed “kickstand screws”, from the metaphyseal portion of a plate toward far-sided articular ...

A 3-dimensional finite element analysis to evaluate the impact of force direction, insertion angle, and cortical bone thickness on mini-screw and its surrounding bone [PDF]
Journal of Dental Research, Dental Clinics, Dental Prospects, 2021 Background. The present study aimed to assess the stress and strain distribution on mini-screws and the surrounding bone in cases of different cortical bone thicknesses (CBTs), mini-screw insertion angles, and force directions using finite element ...

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 ...

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.
