Bone cements are specialized materials used in orthopedic surgeries to anchor implants, such as artificial joints, to the surrounding bone. They are typically made from polymethyl methacrylate (PMMA), a type of acrylic resin that hardens quickly and provides strong adhesion. Bone cements help stabilize implants and improve the overall success of procedures like hip replacements and knee surgeries. These cements are applied in a liquid form and harden within minutes after being mixed with a catalyst. The use of bone cements can enhance the longevity of implants and reduce the risk of complications. Proper application and curing are essential for optimal performance in surgical settings.
