Clinicopathological Study of Chronic Osteomyelitis

Introduction
Overview of chronic osteomyelitis, its definition, causes, and importance of clinicopathological evaluation.

Etiology and Risk Factors
Common causes such as bacterial infection (e.g., Staphylococcus aureus), trauma, surgery, diabetes, and immunocompromised conditions.

Pathogenesis of Chronic Osteomyelitis
Mechanism of infection in bone, formation of sequestrum, involucrum, and chronic inflammatory response.

Clinical Features
Symptoms and signs including bone pain, swelling, sinus formation, fever, and restricted movement.

Diagnostic Methods
Laboratory tests, imaging (X-ray, MRI, CT scan), microbiological culture, and biopsy.

Histopathological Findings
Microscopic features such as necrotic bone, inflammatory cell infiltration, fibrosis, and granulation tissue.

Microbiological Profile
Common microorganisms isolated in chronic osteomyelitis and their antibiotic sensitivity patterns.

Treatment and Management
Antibiotic therapy, surgical debridement, removal of sequestrum, and supportive care.

Conclusion
Summary of clinicopathological findings and the importance of early diagnosis and proper treatment to prevent complications.
