Safety of immediate open traumatic extensor tendon repair performed at an emergency department minor procedure room

Introduction: The superficial location of the extensor tendons makes them particularly vulnerable to lacerations. Patients most commonly present to the emergency department (ED) after these injuries. We aimed to measure the safety of immediate surgical repair of traumatic open extensor tendon injuries in an ED minor procedure room (MPR) under local anesthesia, and the associated post-operative infection and complication rates. Materials and methods: We retrospectively evaluated all patients undergoing traumatic open extensor tendon repairs in the ED MPR over a 3.75-years period. Data collected included demographic information, comorbidities, mechanism of injury, additional procedures performed, and post-operative complications. All patients were operated under local anesthesia by a hand surgery fellow aided by an ED technician. Results: Two hundred and forty eight patients (278 tendons) were treated for extensor tendon injuries during the study period. 220 patients (245 tendons) have complied with follow-up. No intra-procedural medical complications were encountered. The post-operative infection rate was 1.4%. The rate of other post-operative complications was not related to the number of tendons repaired, additional digit involvement, or if the nature of the injury was work-related. Conclusions: In this cohort, traumatic extensor tendon repairs performed in an ED MPR were found to be medically safe and to associate with a low postoperative infection rate. As preoperative assessment is simple and practical, and limited medical personnel is utilized, this surgical setting may enable us to reduce medical costs.
