biomechanical failure
Loss of structural integrity in a fracture repair construct due to inadequate mechanical properties.
Full Definition
Biomechanical failure occurs when the forces acting on a fracture repair construct exceed its mechanical capacity, leading to loss of reduction, hardware breakage, or construct collapse. This can result from inadequate implant selection, poor surgical technique, premature loading, or unexpected high-energy trauma. Biomechanical failure analysis considers factors such as material properties, construct geometry, loading conditions, and bone quality to identify failure modes and prevent recurrence.
Usage
Usage note: Encompasses all mechanical aspects of failure; distinguish from biological causes of treatment failure.
