Abstract:
A retrospective analysis of 332 children with osteomyelitis (OM), managed from 1966 to 1996, was undertaken to evaluate etiology, clinical course and treatment results. In 64% of all patients positive bacterial cultures were obtained, Staphylococcus aureus, streptococci, pneumococci, and Haemophilus influenzae were the most frequently cultured pathogens. In two-thirds of the cases long bones (femur, tibia, humerus) were affected. Osteoarthritis or suppurative arthritis was evident in 27%; 32 of 170 (19%) re-evaluated patients had moderate or severe sequelae. Risk factors for an unfavorable course were the onset of disease in early infancy, suppurative arthritis, and an affected epiphysis. Suppurative arthritis, in particular, needs early evacuation to prevent sequelae. In recent years we observed an increasing number of patients presenting with atypical forms of OM. Since 1989 10 patients were considered to have chronic recurrent multifocal OM (CRMO). In 6 of them the clavicle was involved; their ages ranged from 3 to 14 years. The erythrocyte sedimentation rate was elevated (median 48, range 9-110 mm), while other inflammatory parameters like C-reactive protein (median 9, range <5-85 mg/l) or leucocyte count were slightly elevated or normal. Histopathology was stage-dependent, with a predominance of lymphoplasmacellular infiltration. A nonbacterial origin of CRMO is probable but not proven. Histopathology is not suitable for differentiation between bacterial and nonbacterial forms of bone inflammation.
Insights
This study on pediatric osteomyelitis (OM) found Staphylococcus aureus as a common cause. Early intervention for suppurative arthritis is crucial to prevent long-term complications in children.
Area of Science:
- Pediatric Orthopedics
- Infectious Diseases
- Rheumatology
Background:
- Osteomyelitis (OM) is a significant bone infection in children.
- Understanding its etiology, clinical course, and treatment outcomes is vital for effective management.
Purpose of the Study:
- To retrospectively analyze pediatric osteomyelitis cases managed between 1966 and 1996.
- To evaluate the causative pathogens, clinical presentation, and treatment results.
- To identify risk factors for unfavorable outcomes and explore atypical forms like chronic recurrent multifocal osteomyelitis (CRMO).
Main Methods:
- Retrospective analysis of 332 children diagnosed with osteomyelitis.
- Bacterial culture analysis to identify pathogens.
- Clinical data review for disease course, sequelae, and risk factors.
- Evaluation of 10 patients with suspected CRMO since 1989.
Main Results:
- Bacterial cultures were positive in 64% of cases, with Staphylococcus aureus being the most frequent pathogen.
- Long bones were affected in two-thirds of cases; 27% had associated arthritis.
- Moderate to severe sequelae were observed in 19% of re-evaluated patients.
- Early infancy onset, suppurative arthritis, and epiphyseal involvement were risk factors for poor outcomes.
- Atypical forms, including CRMO (affecting clavicle in 6/10 patients), were observed with elevated ESR but normal inflammatory markers.
- Histopathology in CRMO showed lymphoplasmacellular infiltration, suggesting a probable nonbacterial origin.
Conclusions:
- Staphylococcus aureus is a primary pathogen in pediatric osteomyelitis.
- Prompt surgical drainage of suppurative arthritis is essential to minimize sequelae.
- Chronic recurrent multifocal osteomyelitis (CRMO) presents with distinct clinical and laboratory findings, likely having a nonbacterial etiology, though histopathology is inconclusive for differentiation.
- Risk factor identification aids in predicting and managing pediatric osteomyelitis outcomes.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
