Fatigue failure of cortical bone screws [PDF]

open access: yesJournal 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.

Dynamic Torque Limitation vs Static Torque Limitation for Bone Screws in Pig Bone

open access: yesCurrent Directions in Biomedical Engineering
Correctly torquing bone screws is important to achieve good patient outcomes. An automated system has been previously proposed that may allow more objective torquing of bone screws. Here the system is tested vs. a static torque limit in pig bone.

Can barb thread design improve the pullout strength of bone screws? [PDF]

open access: yes, 2021
Aims: To draw a comparison of the pullout strengths of buttress thread, barb thread, and reverse buttress thread bone screws. Methods: Buttress thread, barb thread, and reverse buttress thread bone screws were inserted into synthetic cancellous bone

The Influence of Design Features in the Biomechanical Performance of a Fixator for the Lumbar Spine [PDF]

open access: yes, 1997
PhDSpinal fixation systems using pedicular screws have gained popularity in manging the damaged spine. However, the loading to which individual components of a fixator are exposed are largely unknown.

Biomechanical comparison of different fixation methods in tibiotalocalcaneal arthrodesis: a cadaver study

open access: yesJournal of Orthopaedic Surgery and Research, 2023
Background Various fixation methods are available for tibiotalocalcaneal arthrodesis: nail, plate, or screws. An intramedullary bone stabilization system within a balloon catheter has not previously been used in tibiotalocalcaneal arthrodesis. The aim of

Influence of thread design on anchorage of pedicle screws in cancellous bone: an experimental and analytical analysis

open access: yesScientific Reports, 2022
Threads of modern pedicle screws can vary greatly in design. It is difficult to assess which interplay of design features is particularly advantageous for screw anchorage.

Torsional stability of interference screws derived from bovine bone - a biomechanical study [PDF]

open access: yes, 2010
Introduction: It has been proposed that individual genetic variation contributes to the course of severe infections and sepsis. Recent studies of single nucleotide polymorphisms (SNPs) within the endotoxin receptor and its signaling system showed an ...
