A Pseudoelastic Approach to Sustain Compression in Bone Fractures and Fusions in Response to Bone Resorption

摘要

A prototype device demonstrated invitro that pseudoelastic materials could be utilizecin high force orthopedic applications to treatfusions and fractures. The pseudoelasticity of NiTiwas shown to be capable of sustaining compressiveloads across a joint for over 6 mm of boneresorption. The addition of NiTi allowed theprototype IM nail to more efficiently store andrecover large str ain deformations, which betterenabled sustained compression. Future studiesshould investigate the amount of resorptionexperienced in vivo as a function ofdynamic, and pseudoelastic fixation mechanisms.
