Summary
Orthopedic implant infections are a significant problem, leading to high costs and poor patient outcomes. Surface modifications offer promising prevention strategies, but long-term antimicrobial activity remains a challenge.
Area of Science:
- Biomaterials Science
- Orthopedic Surgery
- Infectious Disease
Background:
- Bacterial colonization and biofilm formation on orthopedic implants cause severe patient complications and increase healthcare expenses.
- Implant infections can manifest months post-surgery, often due to factors outside surgical control.
Purpose of the Study:
- To review the costs, consequences, prevention, and management of orthopedic implant infections.
- To focus on implant surface modifications with antimicrobial benefits.
Main Methods:
- Classification of antimicrobial coatings based on mode of action: adhesion prevention, bactericidal, antimicrobial-eluting, osseointegration promotion, and combinations.
- Review of current literature on implant surface modification strategies.
Main Results:
- Various surface modification techniques aim to prevent bacterial adhesion and combat infections.
- A key challenge is maintaining antimicrobial efficacy for extended periods (months to years) post-implantation.
Conclusions:
- Implant surface modifications are crucial for preventing orthopedic infections.
- Further research is needed to ensure long-lasting antimicrobial activity of implant coatings for clinical adoption.

2.3K
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...

10.6K
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

5.2K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:30Bacterial Signaling
29.5K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

3.0K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
