Adhesives used to fix prosthetic devices to bones and to cement bone to bone in difficult fractures

Bone cements have been used very successfully to anchor artificial joints (hip joints, knee joints, shoulder and elbow joints) for more than half a century. Artificial joints (referred to as prostheses) are anchored with bone cement. The bone cement fills the free space between the prosthesis and the bone and plays the important role of an elastic zone. This is necessary because the human hip is acted on by approximately 10–12 times the body weight and therefore the bone cement must absorb the forces acting on the hips to ensure that the artificial implant remains in place over the long term.

Bone cement chemically is nothing more than Plexiglas (i.e. polymethyl methacrylate or PMMA).[1] PMMA was used clinically for the first time in the 1940s in plastic surgery to close gaps in the s...
