Overview

Methyl methacrylate (MMA) is the basic component of bone cements. To use it, a dough is prepared from the liquid and powder by mixing right before application, which is normally done by the operating team. During its working phase the dough is then inserted into the tissue where polymerization is completed. Thus, the final implant polymethyl­ methacrylate (PMMA) is only created at the implantation site. Besides methyl methacrylate, bone cements sometimes contain other methacrylates, such as butyl methacrylate. To achieve X-ray opacity, radiopacifiers (zirconium dioxide or barium sulfate) are added to the powder. Both the liquid and powder components contain additives (initiator and activator) that launch polymerization and control the set­ ting when mixed together. Moreover, softener and emulsifiers are some­ times used. The addition of antibiotics to the powder component in order to prevent or treat infections has become especially important. Commercial bone cements differ in composition and the course of curing. Some are designed for high and others for low viscosity. The way the user handles and applies the cement always crucially influences the quality of the implant. This is why clear and comprehensive information about the cements should be available to show the user how all the relevant factors work It should also be possible together and how they depend on each other.

Doody's Review Service
Reviewer: Riad Barmada, MD (University of Illinois at Chicago College of Medicine)
Description: This publication is dedicated to PMMA bone cement, including the various types available and their individual chemical and mechanical properties.
Purpose: The purpose is to provide a reference on the various types of bone cement to help surgeons choose the most suitable type for their procedures.
Audience: Orthopedic surgeons, neurosurgeons, plastic surgeons, and maxillofacial surgeons are the intended audience.
Features: Detailed information on chemical and mechanical properties of various types of bone cement is provided in this book.
Assessment: PMMA bone cement is commonly used in surgery in particular by orthopedic surgeons for joint replacement procedures. The long-term results are affected by the mechanical properties of the type of cement used. With this publication the author provides surgeons with a reference to help them choose the type of cement most suitable to the particular procedure being planned. It is helpful to have this book in an orthopedic library. It is a good reference; it should be available to orthopedic surgeons interested in joint replacement.
