Primary subacute Salmonella osteomyelitis of the navicular bone in a child with normal immunity

Area of Science:

• Pediatric Orthopedics
• Infectious Diseases
• Medical Diagnostics

Background:

• Primary subacute hematogenous osteomyelitis (PSHO) is a bone infection often causing limping, typically in long bones.
• Diagnosis can be challenging and prolonged, often requiring weeks for confirmation.
• While Salmonella spp. can cause PSHO, it's frequently associated with underlying conditions like sickle cell anemia.

Observation:

• This study details a rare case of PSHO in a child with no underlying immune deficiencies.
• The infection specifically affected the navicular bone, a small bone in the foot.
• Salmonella species were identified as the causative agent.

Findings:

• The child presented with symptoms consistent with PSHO, leading to a diagnosis of Salmonella PSHO of the navicular bone.
• The absence of underlying disorders in this patient makes the Salmonella etiology particularly uncommon.
• Timely diagnosis and treatment were crucial for managing the condition.

Implications:

• This case underscores the importance of considering PSHO, even in immunocompetent children presenting with limping.
• It highlights the potential for Salmonella to cause PSHO in small bones like the navicular, irrespective of immune status.
• Early recognition of PSHO is vital for effective treatment and preventing long-term complications.
