600 The Use of a Wide-Awake Local Anaesthesia No Tourniquet (WALANT) Technique in Foot and Ankle Procedures - A Randomised Control Trial

Abstract

IntroductionWide awake local anaesthesia no tourniquet (WALANT) is a widely used technique in upper limb procedures that has gained increasing popularity during the coronavirus pandemic. The benefit of WALANT for foot and ankle surgeries is less clear, especially in patients with multiple comorbities. The primary aim of this study was to compare post-operative pain levels in patients undergoing ankle fracture fixation. Secondary objectives included comparison of intra-operative patient experiences, clinical outcomes, and patient satisfaction 1-year post-procedure.Method129 patients presenting with ankle fractures were enrolled in a multicenter randomised control trial from February 2016 to January 2020. Patients with medial malleolar, lateral malleolar, bimalleolar or trimalleolar fractures received either WALANT (62 patients) or spinal anaesthesia (67 patients). A 5ml solution of 0.9% saline and 2% lidocaine with 1: 100,000 adrenaline was used for WALANT.ResultsCompared to patients who received spinal anaesthesia, those in the WALANT group experienced less post-operative discomfort and were more satisfied 1-year post-procedure (p-value = 0.003). Surgical outcomes were similar for both groups. Cost analysis revealed that WALANT is significantly more economical.ConclusionsWALANT is an effective and safe anaesthetic for foot and ankle procedures. Without use of a tourniquet, it reduces post-operative pain and so, eases patient recovery.
