Chronic humeral osteomyelitis in an adult with sickle-cell disease.

Introduction And Importance: The rising incidence of sickle-cell disease in European countries has led to an increase in associated complications. Osteomyelitis, a rare complication in non-traumatic adult cases, poses diagnostic challenges and presents treatment difficulties due to limited cases and studies.

Case Presentation: A 23-year-old woman diagnosed with sickle-cell disease presented with a six-day fever and painful swelling in the left upper extremity persisting for a fortnight. She had no history of trauma but had experienced a previous episode of bacteremia due to Salmonella, four years prior. Magnetic resonance imaging revealed an intramedullary bone injury with cortical rupture extending into soft tissues, forming a collection that raised clinical suspicion of osteomyelitis, despite negative blood and aspirate cultures. Empiric antibiotic therapy was initiated, followed by surgical debridement of infected tissues. The resulting dead space was filled with antibiotic-coated calcium phosphate beads and tissue grafting. Anatomopathological studies confirmed findings consistent with chronic osteomyelitis. Stabilization of the arm was achieved with an orthopedic brace, and antibiotic administration continued for 6 weeks post-surgery. The injury consolidated 4 months after treatment, and nearly two years later she has not suffered a recurrence.

Clinical Discussion: The scarcity of literature implies the absence of clinical guidelines for treating osteomyelitis in these patients. Empirical antibiotic therapy combined with surgery when there are abscesses that need debridement can be an effective approach.

Conclusion: Humeral osteomyelitis in sickle-cell disease patients can be effectively managed using a pharmaco-surgical strategy, but it should be tailored to the patient's needs.
