Some fracture wound infections present more than 2 weeks after fracture surgery. Often, there are mild systemic, or local, symptoms, such as low-grade fever, or slight local skin reddening. Ultimately, increasing pain, redness and swelling, etc., become evident. Sometimes, late onset of wound breakdown, or drainage (formation of a sinus), is the first indication that an indolent infection is present.
An infection that presents more than 2 weeks after fracture surgery should be considered differently, with the need for more extensive and intensive treatment.
