load transfer
The mechanism by which mechanical forces are transmitted from bone to implant or between bone segments.
Full Definition
Load transfer describes the biomechanical process by which forces applied to a bone-implant construct are distributed between the native bone and the orthopedic hardware. Understanding load transfer is crucial for implant design and surgical technique, as improper load distribution can lead to stress shielding, implant failure, or delayed bone healing. The goal is typically to achieve appropriate load sharing that promotes bone healing while preventing overload of either the bone or the implant. Factors affecting load transfer include implant stiffness, bone quality, fracture pattern, and the degree of bone-implant contact. Modern implant designs increasingly focus on optimizing load transfer characteristics.
Usage
Usage note: Use when discussing the biomechanical interaction between bone and implant, not just general force application.
