Background: We present the description of a supramalleolar ankle block technique and our experience using this technique in foot and ankle surgery. Materials and Methods: We performed a retrospective observational study of the past 5 years of patients with foot and ankle pathology that had undergone the supramalleolar ankle block. We excluded patients with a history of previous foot surgery, bilateral surgeries, vascular disease, peripheral neuropathy, diabetes, smoking, or active surgical site infection. The supramalleolar ankle block was guided by anatomic landmarks and we used a solution of lidocaine 2% and bupivacaine 0.5%. We evaluated the duration of the ankle block, the visual analog scale (VAS) for pain 24 hrs after surgery, the time until the first analgesic dose, and the level of patient satisfaction. Results: 771 patients were included in this study, all of whom had complete analgesia for at least 12 hrs (mean 18 hrs) after surgery. The mean value on the VAS for pain after 24 hrs was 1.4. On average, the first analgesic dose was administered 16 hrs after surgery. The level of satisfaction about the pain perceived in the first 24 hrs after surgery was: very satisfied (89%), satisfied (10%), and dissatisfied (1%). There were no reports of permanent neurological sequelae, systemic toxicity, or surgical site infections. Conclusion: We consider the supramalleolar ankle block a simple, effective, and safe procedure to obtain long-lasting postoperative analgesia.
