Bone Cemment- PMMA
Polymethylmethacrylate (PMMA) is a commonly used material in orthopedic surgery for bone cementing applications. It is a biocompatible material that has been used for decades to help anchor artificial joints in place, repair fractures, and treat bone defects.
PMMA bone cement is typically mixed with a monomer liquid to create a paste that can be injected into the bone. As the paste hardens, it creates a stable bond between the bone and the implant, providing immediate stability and support.
In orthopedic surgery, PMMA bone cement is primarily used in joint replacement procedures, such as total hip arthroplasty, total knee arthroplasty, and total shoulder arthroplasty. It is also used in vertebroplasty and kyphoplasty procedures to treat vertebral fractures caused by osteoporosis or cancer.
While PMMA bone cement is generally considered safe and effective, there are some risks associated with its use. These include the risk of infection, allergic reaction, and bone cement implantation syndrome (BCIS), which can cause hypotension, hypoxia, and cardiac arrest.
Overall, PMMA bone cement is a valuable tool in orthopedic surgery, providing stability and support to help patients regain mobility and improve their quality of life.
