Abstract:
Due to systemic or local antibiotic treatment and other preventive procedures, the incidence of deep hip-prosthetic infections in Scandinavia is less than 1 percent, with the majority hematogenous. Coagulase-negative staphylococci and anaerobes are involved in more than half of the cases. The diagnosis is sometimes difficult; preoperative aspiration often gives misleading results; and granulocyte scanning usually adds valuable information. In deep infection the current strategy is to revise with a two-stage procedure. Revisions should be carried out at specialized centers with bacteriologic competence and sufficient experience with implants.
Insights
Deep hip-prosthetic infections are rare (<1%) in Scandinavia, often caused by staphylococci or anaerobes. Diagnosis can be challenging, but two-stage revision surgery is the current treatment strategy.
Area of Science:
- Orthopedic Surgery
- Infectious Diseases
- Biomedical Engineering
Background:
- Deep hip-prosthetic infections (DHPI) incidence is low (<1%) in Scandinavia due to preventive measures.
- Hematogenous spread is the primary route for DHPI, with coagulase-negative staphylococci and anaerobes being common pathogens.
Purpose of the Study:
- To review the diagnostic challenges and current management strategies for deep hip-prosthetic infections.
- To emphasize the importance of specialized centers for revision surgery.
Main Methods:
- Review of existing literature and clinical practices regarding deep hip-prosthetic infections.
- Discussion of diagnostic tools, including preoperative aspiration and granulocyte scanning.
- Analysis of the current treatment paradigm, focusing on two-stage revision procedures.
Main Results:
- Preoperative aspiration for diagnosis can be unreliable.
- Granulocyte scanning provides valuable diagnostic information.
- Two-stage revision surgery is the established strategy for managing deep hip-prosthetic infections.
Conclusions:
- Effective management of deep hip-prosthetic infections requires accurate diagnosis and specialized surgical intervention.
- Revision surgeries for deep hip-prosthetic infections should be performed at centers with expertise in implants and bacteriology.
