Adjustable Stiffness, External Fixator for the Rat Femur Osteotomy and Segmental Bone Defect Models

¹Institute of Health and Biomedical Innovation, Queensland University of Technology, ²RISystem AG

One constraint of preclinical research in the field of bone repair is the lack of experimental control over the local mechanical environment within a healing bone lesion. We report the design and use of an external fixator for bone repair with the ability to change fixator stiffness in vivo.
