Biomechanical Comparison of Two Fixation Methods for First Metatarsophalangeal Joint Arthrodesis

Biomechanical Comparison of Two Fixation Methods for First Metatarsophalangeal Joint Arthrodesis

Purpose: The aim of this study was to compare the mechanical stability of two methods of fixation for arthrodesis of the hallux metatarsophalangeal joint: a technique using an intramedullary screw and a standard technique using crossed interfragmentary compression screws. Methodology: The metatarsop...

Zusammenfassung:Purpose: The aim of this study was to compare the mechanical stability of two methods of fixation for arthrodesis of the hallux metatarsophalangeal joint: a technique using an intramedullary screw and a standard technique using crossed interfragmentary compression screws. Methodology: The metatarsophalangeal joint was mechanically evaluated in cantilever bending using a servohydraulic testing machine. Differences in stiffness and strength parameters between the two techniques were checked for significance (P
