Background:. Prior evidence is clear that in clean, elective soft-tissue hand procedures less than 2 hours, antibiotic prophylaxis is not indicated. However, there is a lack of consensus regarding the boney procedures of the hand involving implanted hardware. Previous studies reviewing complications after distal interphalangeal (DIP) joint arthrodesis did not analyze whether patients receiving antibiotics before surgery had a significant difference in the infection rate. Methods:. A retrospective review of clean, elective DIP arthrodesis was conducted between September 2018 and September 2021. The subjects were aged 18 years and older and underwent elective DIP arthrodesis for the treatment of osteoarthritis or deformity of the DIP joint. All the procedures were performed using an intramedullary headless compression screw. The rates of postoperative infections and treatments required for infections were recorded and analyzed. Results:. Overall, 37 unique patients had at least one case of DIP arthrodesis that met the criteria for inclusion in our analysis. Twenty of the 37 patients did not receive antibiotic prophylaxis, and 17 of the 37 patients received antibiotic prophylaxis. Five of the 20 patients who did not receive antibiotics prophylactically developed infections, and none of the 17 patients who received antibiotics prophylactically developed an infection. Fisher exact test revealed a significant difference in the infection rates between the two groups (P < 0.05). There was no significant difference in infections with respect to smoking or diabetes status. Conclusion:. Antibiotic prophylaxis should be administered for clean, elective DIP arthrodesis, using an intramedullary screw.
