[Diagnosis and management of chronic osteomyelitis of long bones in adults].

Chronic osteomyelitis is an inflammatory process of the bone caused by an infectious agent. This condition leads to altered bone vascularization and thus to bone destruction and formation of necrotic bone fragments (sequestrum). The treatment of chronic osteomyelitis is primarily based on surgical management, which includes debridement of the sequestrum and sampling of bone tissue for microbiological analysis in order to initiate a targeted antibiotic therapy. A multidisciplinary approach is essential, involving expertise in orthopedic surgery, musculoskeletal imaging and nuclear medicine, infectious diseases, as well as plastic or vascular surgery for complex cases with soft tissue and/or vascular defects.
