Infection of the “simple” open fractureof the distal radius is a significant-but fortunately rare-complication ofimmobilizing musculoskeletal injuriesof the upper extremity. Cliniciansoften underestimate the extent towhich this type of fracture can be contaminated,particularly if the patientpresents with a small puncture wounddirectly over the fractured distal radiusthat conceals the degree of contaminationat the fracture site. If openfractures of the distal radius are simplywashed out in the emergency department and temporarily splinted, overwhelming sepsis fromclostridial myonecrosis may develop, leading to amputation.
