Polymethylmethacrylate: properties and contemporary uses in orthopaedics
1Department of Orthopaedics, St. Vincent Mercy Medical Center, Toledo, OH, USA.
Summary
Polymethylmethacrylate (PMMA) is a versatile biomaterial used in orthopaedics since the 1940s. Its properties vary due to modifications, enabling antibiotic delivery and dead space elimination in procedures like hip arthroplasty.
Area of Science:
- Orthopaedic surgery
- Biomaterials science
- Medical device engineering
Background:
- Polymethylmethacrylate (PMMA) has been a staple in orthopaedics since the 1940s.
- Despite advancements, PMMA remains widely used due to its adaptability.
- Variations in PMMA properties arise from subtle changes in composition and environmental factors.
Purpose of the Study:
- To review the enduring role and characteristics of Polymethylmethacrylate (PMMA) in orthopaedic applications.
- To highlight the factors influencing PMMA performance and its utility as a drug delivery vehicle.
- To discuss common orthopaedic uses and potential complications associated with PMMA.
Main Methods:
- Literature review of Polymethylmethacrylate (PMMA) applications in orthopaedics.
- Analysis of factors affecting PMMA properties and performance.
- Summary of clinical uses and reported adverse events.
Main Results:
- PMMA continues to be a popular orthopaedic biomaterial.
- Its properties can be modulated by proprietary and environmental factors.
- PMMA serves as a spacer, antibiotic delivery vehicle, and dead space filler.
- Key applications include hip arthroplasty and vertebral augmentation (vertebroplasty, kyphoplasty).
- Cardiopulmonary complications have been associated with PMMA use.
Conclusions:
- Polymethylmethacrylate (PMMA) remains a relevant and adaptable biomaterial in modern orthopaedics.
- Understanding variables affecting PMMA is crucial for optimizing patient outcomes.
- Awareness of potential complications, such as cardiopulmonary events, is essential for safe clinical practice.

01:28Classification and Mechanical Properties of Synthetic Polymers
Synthetic polymers are classified as elastomers, fibers, or plastics based on their crystallinity. Crystallinity, the degree of long-range order in the solid state, influences the mechanical properties (stretching or contracting) of elastomers. Elastomers are flexible polymers that can expand or contract easily upon the application of an external force. They have numerous crosslinks that pull them back into their original shape when stress is removed. Silicones, for instance, are highly elastic...
01:20Anionic Chain-Growth Polymerization: Overview
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...
