Abstract:
Subacute acetabular osteomyelitis is a rare disease of bone. Deep location of the infection site sometimes may delay diagnosis. The most common cause is Staphylococcus aureus, whereas Proteus organisms are very rare etiologic agents. The aim of this case report is to present an unusual case of subacute acetabular osteomyelitis caused by Proteus mirabilis in a 12-year-old boy. Subacute acetabular osteomyelitis can be induced by Proteus mirabilis in the absence of previous trauma, predisposing conditions or disease. The patient was successfully treated with antibiotics. Local biopsy was essential in diagnosing this infection. Antibiotics should be given only after clinical sampling and susceptibility tests.
Insights
This case report details a rare instance of subacute acetabular osteomyelitis in a child caused by Proteus mirabilis. Prompt diagnosis and antibiotic treatment following biopsy were crucial for successful recovery.
Area of Science:
- Orthopedics
- Infectious Diseases
- Microbiology
Background:
- Subacute acetabular osteomyelitis is an uncommon bone infection, often challenging to diagnose due to its deep-seated nature.
- Staphylococcus aureus is the typical pathogen, while Proteus species are infrequent causes of this condition.
Observation:
- A 12-year-old boy presented with subacute acetabular osteomyelitis.
- The infection was caused by Proteus mirabilis, an unusual causative agent for this condition, occurring without preceding trauma or predisposing factors.
Findings:
- Local biopsy confirmed Proteus mirabilis as the etiologic agent, highlighting its role in rare osteomyelitis cases.
- The patient received successful treatment with antibiotics, emphasizing the importance of targeted therapy.
Implications:
- This case underscores that Proteus mirabilis can cause subacute acetabular osteomyelitis even in healthy individuals.
- Accurate diagnosis relies on biopsy and susceptibility testing before initiating antibiotic therapy for bone infections.
