Diluted povidone-iodine versus saline for dressing metal-skin interfaces in external fixation

Description: PURPOSE: To compare infection rates associated with 2 dressing solutions for metal-skin interfaces. METHODS: 60 patients who underwent distraction osteogenesis with external fixators were equally randomised into 2 dressing solution groups (diluted povidone-iodine vs. saline).
CONCLUSION: Saline is as effective as diluted povidone-iodine as a dressing solution for metal-skin interfaces of external fixators. Saline is recommended in view of its easy availability and lower costs.
