The infection primarily affects the musculoskeletal system, most frequently involving bones of the hands, wrists, or feet

Pathophysiologically, the condition is characterized by rapid local inflammatory tissue destruction, marked localized pain, swelling, erythema, periosteal reaction, and potential progression to bone necrosis or sinus tract formation
