Wound infection after fracture surgery can cause many serious consequences, analyzed in different severity in the following aspects: 1. Wound infection can have long-lasting secretions exuding, affecting the healing of the wound, and there is no way to remove the stitches within half a month. 2. Long-term infection can lead to tissue necrosis in the area, the foci of infection expand, and over time can cause infection of the bone and eventually osteomyelitis. 3. Still not under control, osteomyelitis is not actively treated and turns into chronic osteomyelitis, which can lead to severe osteoporosis in the area over time and can cause non-healing of the fracture. In this case, repeated surgical treatment or even the removal of the internal fixation of the surgical site may not be able to completely control the infection, so the situation of infection must be actively treated.
