AbstractBackground: Open surgical release of the A1 pulley is the definitive treatment for the common hand condition of trigger finger, or inflammatory stenosing tenosynovitis. Anecdotal evidence among hand surgeons has questioned whether or not recent steroid injection may be related to complications following open trigger finger release, particularly wound infection, but no studies have primarily studied this connection to date. We aimed to determine whether recent steroid injection was associated with postoperative surgical infections. Methods: We performed a retrospective chart review of 780 adult patients who had undergone open trigger finger release of 999 digits by 6 fellowship-trained hand surgeons at three affiliated hospital settings from January 1, 2014, to January 1, 2016. Data on timing of steroid injections relative to surgery, number of steroid injections, concomitant conditions, use of antibiotics, and postoperative complications including infections were gathered. Results: Steroid injection timing relative to subsequent operative intervention correlated with postoperative surgical site infection in trigger finger release. Older age and decreasing days between steroid injection and surgery correlated with infection rates. Other factors found to be associated with infection rates included smoking, use of preoperative antibiotics, and use of lidocaine with epinephrine. The other factors examined did not correlate with infection rates. Conclusions: Steroid injection, smoking, increasing age, lesser number of days between steroid injection and surgery, and use of lidocaine with epinephrine are risk factors for postoperative trigger surgical infections. We recommend careful preoperative counseling regarding higher wound healing risks for smokers, avoidance of steroid injections immediately prior to an operative date, and scheduling operative dates that tend to be greater than 80 days from the date of last steroid injection. We also recommend avoidance of epinephrine in the local anesthetic solution, as this may minimize surgical site infection risks.
