bone void filler
Synthetic or biological material used to fill defects in bone during fracture repair or reconstruction.
Full Definition
Bone void filler is a material used to occupy empty spaces within bone that result from trauma, surgical procedures, or pathological conditions. These materials can be synthetic (such as calcium phosphate ceramics), biological (such as demineralized bone matrix), or composite substances designed to promote bone healing. Void fillers serve multiple purposes including providing structural support, facilitating bone ingrowth, and delivering therapeutic agents. The choice of void filler depends on the defect size, location, mechanical requirements, and desired biological properties. These materials are particularly important in metaphyseal fractures where bone loss creates cavities after reduction.
Usage
Usage note: Distinguish from traditional bone grafts; emphasize the void-filling function.
