The term "Acrylic Bone Cement" refers to a surgically used material that helps to attach artificial joints and implantable medical devices to human bones. The spelling of this word is "uh-kree-lik bohn see-ment" in the International Phonetic Alphabet (IPA). The word "acrylic" derives from the chemical component "acrylate" and "cement" relates to the material's adhesive properties. The correct spelling of this term is essential in the medical field to ensure the proper application of the product and for accurate communication between healthcare providers.
Acrylic bone cement is a type of adhesive material commonly used in orthopedic surgeries to anchor artificial joints, such as hip or knee replacements, to the patient's existing bone structure. It is a biocompatible substance made from a powdery mixture of polymethylmethacrylate (PMMA) powder and a liquid monomer, usually methyl methacrylate (MMA). When these two components are mixed together, a chemical reaction called polymerization occurs, causing the liquid to harden and form a solid mass.
This bone cement is specifically designed to have suitable mechanical properties to provide stability and fixation between the implant and the surrounding bone. It bonds firmly with both the artificial joint and the natural bone, creating a secure and durable connection. The solidified acrylic cement acts as a grout or filler, filling any gaps or irregularities between the implant and the bone, ensuring a secure and stable fit.
Acrylic bone cement has excellent strength and wear resistance, allowing it to withstand the forces exerted during weight-bearing activities. It also provides insulation and acts as a barrier between the metal implant and the surrounding tissue, minimizing the risk of inflammation or immune reactions.
Overall, acrylic bone cement plays a crucial role in the success of joint replacement surgeries, ensuring the longevity and functionality of the artificial joint by providing stability, fixation, and load transmission between the implant and the patient's bone.
