For external fixator pin care, which practice is recommended?

• A. Apply full-strength hydrogen peroxide to pins
• B. Perform sterile pin care using 1/2-strength hydrogen peroxide and normal saline or chlorhexidine
• C. Soak pins in iodine solution continuously
• D. Avoid touching pins and wash hands only

Answer: (B)

Prevent pin-site infections by using aseptic technique and gentle cleansing with a mild antiseptic. The best approach combines sterile pin care with a diluted antiseptic and compatible irrigation solution. Using diluted hydrogen peroxide helps loosen crusts without causing tissue damage, and pairing it with normal saline or chlorhexidine provides effective antisepsis while minimizing cytotoxic effects. This balanced plan protects tissue around the pins and reduces infection risk.

Full-strength hydrogen peroxide can irritate or injure surrounding tissue, making healing slower. Soaking pins in iodine continuously isn’t recommended due to irritation and potential tissue damage. Merely washing hands without cleaning around the pins leaves the pin tract vulnerable to infection.
