Abstract:
Fracture related infection remains a challenging complication that creates a heavy burden for orthopaedic trauma patients, their families, treating physicians and healthcare systems. Even current curative approaches (radical debridement, revision surgery and long-term antibiotics) often result in significant socioeconomic costs and the risk of life-long functional impairment to the patient. The prevalence of osteomyelitis due to trauma and surgical complications does not seem to be diminishing in our society and the emergence of antimicrobial resistance is a major health related concern with global relevance. Despite multi-drug resistant bacteria being on the rise universally, perioperative antibiotic prophylaxis in orthopaedic trauma care has only slightly changed in the last 25 years. Staphylococcus infections remain an increasing global concern, partially due to the resistance mechanisms developed by staphylococci to evade the host immune system and antibiotic treatment, and as such antibiotics are becoming increasingly ineffective. This paper will address fracture related infections in trauma patients, looking at the bacteriology of these infections, its clinical implications and evolving nature.
Insights
Fracture related infections pose a significant burden, with current treatments often failing due to rising antimicrobial resistance. This review examines the evolving nature of these infections, focusing on Staphylococcus strains and their impact on osteomyelitis treatment.
Area of Science:
- Orthopaedic Trauma Surgery
- Infectious Diseases
- Microbiology
Background:
- Fracture-related infections (FRI) present a substantial challenge in orthopaedic trauma care, leading to significant patient morbidity and healthcare costs.
- Existing treatments like debridement, revision surgery, and prolonged antibiotics have limitations and can result in long-term functional impairment.
- The increasing prevalence of osteomyelitis and the global rise of antimicrobial resistance, particularly from Staphylococcus species, necessitate a re-evaluation of current practices.
Purpose of the Study:
- To review the current landscape of fracture-related infections in trauma patients.
- To explore the bacteriology, clinical implications, and evolving nature of these infections.
- To highlight the growing challenge posed by antimicrobial resistance in Staphylococcus infections.
Main Methods:
- Literature review of fracture-related infections, osteomyelitis, and antimicrobial resistance in orthopaedic trauma.
- Analysis of bacteriological data and clinical outcomes associated with Staphylococcus infections.
- Discussion of the limitations of current treatment strategies and antibiotic prophylaxis.
Main Results:
- Fracture-related infections are a persistent complication with high socioeconomic and patient-related costs.
- Antimicrobial resistance is escalating, rendering standard antibiotic treatments increasingly ineffective, especially against Staphylococcus strains.
- Current perioperative antibiotic prophylaxis protocols have seen minimal changes despite the rise in resistant bacteria.
Conclusions:
- Fracture-related infections, particularly those caused by resistant Staphylococcus, represent a critical and evolving challenge in orthopaedic trauma.
- There is an urgent need to address the ineffectiveness of current treatments and adapt strategies to combat rising antimicrobial resistance.
- Further research into novel approaches for managing these complex infections is essential.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
