Sternal osteomyelitis - Surgical treatment concepts

Sternal osteomyelitis is a potentially fatal condition following cardiac surgery. Sternal osteomyelitis should be diagnosed as early as possible followed by an interdisciplinary radical debridement. Subsequently plastic reconstructive surgery is necessary for defect reconstruction. This can be achieved by a number of established pedicled and free flap plastic surgery procedures. The choice of flap procedures is based on defect geometry and the individual patient situation, including potential flap donor sites. Smaller defects can generally be reconstructed by pedicled flap transfer. For extensive sternal defects, free flap transplantation is now a well-established therapeutic option. In some patients lacking sufficient recipient vessels, the creation of an arteriovenous (AV) loop as recipient vessel is necessary. In summary, successful therapy of sternal osteomyelitis is based on early interdisciplinary treatment by the various surgical subspecialties.
