196 – Does WALANT for tibia/fibula fracture fixation have an increased risk of VTE events?

196 – Does WALANT for tibia/fibula fracture fixation have an increased risk of VTE events?

Thomas Volk, Jeffrey Mojica, Azlina Amir Abbas.

Response/Recommendation: Whether wide-awake local anesthesia no tourniquet (WALANT) for tibia/fibula fracture fixation has a risk of venous thromboembolism (VTE) compared to other techniques for tibia/fibula fracture is unknown. We recommend using anticoagulant prophylaxis as per existing thromboprophylaxis guidelines, independent of the technique used.

Strength of Recommendation: Moderate.

Rationale: WALANT is a surgical technique that was first described by Dr. Donald H. Lalonde for surgery of the wrist and hand1. To perform the technique, the surgeon injects a lidocaine and epinephrine mixture into the operative site. The lidocaine provides surgical anesthesia and allows the patient to remain comfortably awake during the procedure. The epinephrine assists in hemostasis and eliminates the need for a tourniquet1. Aside from wrist and hand surgery, WALANT has been successfully used for plate fixation of distal radius fractures2 and clavicular fractures3. The successful application of WALANT for upper extremity fracture repair has prompted investigations in its utility for lower extremity fractures.

The literature on WALANT for lower extremity fractures is limited. We identified a case report, published as an abstract from a scientific meeting describing the use of WALANT in a patient that underwent plating of a proximal tibia fracture. The authors did not report any complications4. Li et al., described a prospective case series of 13 patients using WALANT for malleolar fractures and no complications, including VTE, were reported5. Bilgetekin et al., performed a retrospective chart review of 31 patients that underwent WALANT for foot and ankle surgery6. Of these patients, 20 had malleolar fractures and no complications, including VTE, were reported. Poggetti et al., studied the use of WALANT for the removal of distal fibula implants7. In their study, 60 patients were scheduled for distal fibula hardware removal following open reduction internal fixation and were randomized to receive either WALANT or a stimulation-guided sciatic and femoral nerve block with tourniquet. The primary outcome was not defined, and like the previous studies, no VTE were reported7. Overall, these studies are limited by their small size, heterogeneity, and lack of power to detect VTE complications. As a result, the risk of VTE in patients receiving WALANT for tibia/fibula fracture fixation remains poorly defined and we are unable to recommend a specific anticoagulant regimen for thromboprophylaxis
