Introduction

Fracture-related infection (FRI) is a serious complication that can occur following a fracture or orthopedic surgery. It occurs when bacteria invade the bone, surrounding soft tissues, or implants, leading to infection. FRI can be challenging to diagnose and treat, often requiring a multidisciplinary approach involving orthopedic surgeons, infectious disease specialists, and microbiologists. Understanding the nature of FRI is crucial for effective management and prevention of this debilitating condition.

Causes and Risk Factors

FRI can be caused by a variety of bacteria, with Staphylococcus aureus being the most common pathogen. Risk factors for developing FRI include open fractures, contaminated wounds, previous infections, and the presence of foreign bodies such as implants. Patients with compromised immune systems or chronic medical conditions are also at a higher risk for developing FRI. Understanding these risk factors can help clinicians identify patients who are at a higher risk and implement preventive measures.

Clinical Presentation and Diagnosis

The clinical presentation of FRI can vary widely, with symptoms ranging from localized pain, swelling, and redness to systemic signs of infection such as fever and chills. Diagnosing FRI can be challenging, as conventional imaging studies such as X-rays and CT scans may not always detect the infection. In some cases, a bone biopsy or joint aspiration may be necessary to confirm the diagnosis. Blood tests such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) can also be helpful in supporting the diagnosis of FRI.

Treatment and Management

Treatment of FRI typically involves a combination of surgical intervention and antibiotic therapy. Surgical debridement of infected tissues and implant removal may be necessary to eliminate the source of infection. Antibiotics are usually prescribed for a prolonged duration to eradicate the bacteria. In some cases, antibiotic-impregnated bone cement or beads may be used to deliver high concentrations of antibiotics directly to the infection site. Close monitoring of the patient’s clinical response and serial imaging studies are essential to ensure successful treatment of FRI.

Fracture-related infection is a complex and challenging condition that requires a multidisciplinary approach for effective management. By understanding the causes, risk factors, clinical presentation, and treatment options for FRI, healthcare providers can better diagnose and treat this serious complication. Early recognition and prompt intervention are crucial in preventing long-term complications and improving patient outcomes.
