buttress plate
An orthopedic implant that supports bone against axial loading forces and prevents collapse.
Full Definition
A buttress plate is a type of fixation device positioned to resist compressive and shear forces that could cause fracture collapse or angulation. Unlike compression plates that create interfragmentary compression, buttress plates act as internal scaffolding to maintain bone alignment under physiological loads. They are particularly important in metaphyseal fractures where bone quality is compromised. Editors should note that buttress plates function differently from compression plates and serve a load-sharing rather than load-bearing role.
Usage
Usage note: Specify the direction of buttressing (lateral, medial, anterior, posterior) in surgical descriptions.
