Current Trends in Thromboprophylaxis in Surgery of the Foot and Ankle

Abstract

Background: Few studies exist to guide the best practice in thromboprophylaxis after foot and ankle surgery. A survey of foot and ankle surgeons was performed to assess current trends in thromboprophylaxis. Methods: An email-based survey of American and British foot and ankle surgeons was conducted. Surgeons were questioned as to their use and type(s) of thromboprophylaxis as well as reasons for not using prophylaxis. Surgeons also were asked about their use of thromboprophylaxis in hip and knee arthroplasty, if they did these surgeries. Results: Nearly one-fifth (19%, 27) of surgeons routinely used thromboprophylaxis in both elective and trauma foot and ankle surgery. The most common situation for use was in a postoperative patient who was immobilized and nonweightbearing. A lack of published evidence and a low rate of thromboembolism were the most commonly cited reasons for not using thromboprophylaxis. Conclusions: This survey showed a wide variability in thromboembolic prophylaxis. It suggests that despite the literature indicating to the contrary, a significant proportion of foot and ankle surgeons routinely use thromboprophylaxis. Confusion remains regarding the appropriateness of thromboprophylaxis and what type(s)(if any) should be used. This study has identified a need for more in-depth evaluation of the importance of, and possible prophylaxis against, thromboembolic problems after foot and ankle surgery.
