Acute chest wall infections are uncommon and share similar risk factors for infection at other surgical sites. Smoking cessation has been shown to decrease the risk of surgical site infection. Depending on the depth of infection and/or involvement of the organ space, adequate therapy involves antibiotics and drainage. Early diagnosis and debridement of necrotizing soft tissue infections is essential to reduce mortality. Sternoclavicular joint infections require surgical debridement, en bloc resection, and antibiotic therapy. A standard approach to wound closure after resection has yet to be established. Vacuum-assisted closure is a valuable adjunct to standard therapy.
