Bone Cement

Description

This video introduces OrthoM8 and discusses the revolutionary material polymethyl methacrylate (PMMA) in orthopedics. The speaker begins by examining PMMA's history since the 1940s and its ongoing popularity despite newer materials. PMMA is made up of a polymer powder and a monomer liquid, with specific components that facilitate its unique properties. The curing process is highlighted, detailing the exothermic reactions and temperature ranges during hardening. The mechanical strengths of PMMA are compared to both cancellous and cortical bone, emphasizing its compressive strength. Factors influencing PMMA's properties are discussed, including variations in components and environmental conditions. The material is used in various orthopedic applications, such as hip arthroplasty and antibiotic delivery; however, potential cardiopulmonary complications necessitate further research. The video concludes by summarizing PMMA's importance and encourages viewers to subscribe.
