Pelvic osteomyelitis is a challenging infection often caused by contiguous spread, direct inoculation, or hematogenous dissemination, with key risk factors including trauma, surgery, radiation, and intra-abdominal or genitourinary infections. Diagnosis relies on bone biopsy with culture and histopathology, and MRI is the most sensitive imaging study. Treatment requires surgical debridement with extended antimicrobial therapy. Local antibiotic therapy can provide targeted antimicrobial treatment at the site of infection, enhancing the effectiveness of systemic antibiotics. Early recognition, thorough diagnostic workup, and individualized treatment strategies are crucial for improving outcomes in this complex condition.
