Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome, is an often overlooked cause of orthopaedic-related infections despite a well-accepted association in the literature. We present the case of a forty-seven-year-old man with HHT who developed femoral osteomyelitis and a subsequent pathologic femoral fracture from a rare bacterial species associated with HHT.
Patients with HHT and extremity pain should be carefully evaluated for orthopaedic infections. If an orthopaedic infection is suspected, fastidious organisms should be considered as a possible etiologic agent. PCR (polymerase chain reaction) is helpful when organisms cannot be isolated from traditional culture media.
