Biomechanical Principles of Fracture Healing

Osteogenic tissues are remarkably mechanosensitive during both growth and repair. Thus, it is important for a surgeon aiming to optimize bone regeneration to create an ideal mechanical environment with the surgical protocol, implants, and postsurgical weight-bearing they select. Here, we discuss the basics of mechanical strength from both the material and structural perspectives for fracture callus tissues and implant materials. After reviewing this chapter, the reader should be able to find characteristic points on a stress-strain curve and to categorize material properties (i.e., stiff vs. compliant, strong vs. weak, ductile vs. brittle). The following topics are also covered: anisotropy, fatigue failure, viscoelasticity, and stress concentrations.
