Artificial bone refers to bone-like material created in a laboratory that can be used in bone grafts, to replace human bone that was lost due to severe fractures, disease, etc. [1] Bone fracture, which is a complete or partial break in the bone, is a very common condition that has more than three million US cases per year. [ 2 ]
Osteoconduction is termed as "the property of a material to support tissue ingrowth, osteoprogenitor cell growth, and development for bone formation to occur". [2] In the context of bone grafting it occurs when the bone graft material serves as a scaffold for new bone growth that is perpetuated by the native bone.
Osseointegration is also defined as: "the formation of a direct interface between an implant and bone, without intervening soft tissue". [1]An osseointegrated implant is a type of implant defined as "an endosteal implant containing pores into which osteoblasts and supporting connective tissue can migrate". [2]
Hot isostatic pressing (HIP) is a manufacturing process, used to reduce the porosity of metals and increase the density of many ceramic materials. This improves the material's mechanical properties and workability. The process can be used to produce waste form classes.
Hip replacement is a surgical procedure performed in dogs and cats as a salvage procedure, to alleviate severe pain in the hip due to, for example, hip dysplasia or irreparable bone fracture. [1] [2] The procedure replaces the head of the femur and the acetabulum with prosthetic implants. [1]
Zones of a hip prosthesis, by the DeLee and Charnley system, [1] and the Gruen system. [2] After hip replacement, hip prosthesis zones are regions in the interface between prosthesis material and the surrounding bone. These are used as reference regions when describing for example complications including hip prosthesis loosening on medical imaging.
