Overview
Infective discitis involves inflammation of the intervertebral disc space, often secondary to hematogenous spread or direct inoculation, frequently caused by bacteria such as MRSA 1.Diagnosis
Clinical Presentation: Severe back pain, often with systemic signs of infection 1.
Imaging: Plain radiographs showing endplate destruction and disc space narrowing; MRI confirms inflammation and can detect complications like pseudoaneurysms 1.
Culture and Sensitivity: CT-guided biopsy essential for definitive diagnosis and identifying pathogens like MRSA 1.Management
Antibiotics: Targeted therapy based on culture results; for MRSA, consider vancomycin or linezolid 1.
Surgical Intervention: May be required for abscess drainage or stabilization in cases of significant structural damage 1.
Adjunctive Treatments: Pain management and immobilization as needed 1.Special Populations
Elderly: Increased risk of complications such as pseudoaneurysms post-procedural interventions 1.Key Recommendations
Perform CT-guided biopsy for definitive diagnosis and culture in suspected infective discitis (Evidence: Moderate 1).
Initiate targeted antibiotic therapy based on culture and sensitivity results, especially for MRSA infections (Evidence: Moderate 1).
Consider percutaneous thrombin injection for managing complications like pseudoaneurysms following interventional procedures (Evidence: Weak 1).References
