Figure 1 Presentation of the patient. A: Skin sinus of the patient; B: Preoperative X-ray showing the infectious nonunion of the left radius.

Figure 2 Debridement and cement implantation to the patient. A: Infectious focus of the left radius; B: Removal of the implant and infectious bone segment; and placement of drainage tubes and vacuum sealing drainage; C: X-ray after debridement; D: Effective resolution of the focus; E: Placement of the antibiotic spacer and external fixation; F: X-ray after placement of the antibiotic spacer and external fixation.
