Infections of the upper extremity can be challenging to diagnose and treat because of the complex anatomy and range of offending pathogens. Early recognition of infections that require an emergent surgical intervention, such as necrotizing fasciitis and septic joints, is imperative for good clinical outcomes. In addition, prompt diagnosis and intervention for deep closed space infections, such as deep abscesses or flexor tenosynovitis, is necessary to avoid chronic pain and dysfunction. Complicating factors such as underlying osteomyelitis, atypical pathogens, and immunocompromised states of patients should always be considered when treating upper-extremity infections.
