  • Title: Biomechanical comparison of five external wrist fixators.
    Author: Chang D, Kummer FJ, Egol K, Tejwani N, Wolinsky P, Koval KJ.
    Journal: Bull Hosp Jt Dis; ; 61(1-2):40-4. PubMed ID: 12828378.
    Abstract:
    The relative stiffness of five different external wrist fixators currently in use for distal radius fractures was determined using a uniform fracture model consisting of wood dowels to isolate the effects of the fixators themselves. Each construct was loaded in axial compression, eccentric and cantilever modes of bending, and torsion. The stiffest of the fixators varied by a factor of three in compression, five in bending, and three in torsion. Although the ideal stiffness of a wrist fixator is unknown, there is a large variation in the stiffness of existing devices.
