Foot Surgery

Distal upper limb and distal lower limb surgery performed under local anesthesia using the WALANT technique (Wide Awake Local Anesthesia No Tourniquet) has become standard practice in ambulatory orthopedic surgery. Current infiltration mixtures used by orthopedic surgeons include lidocaine-epinephrine with the addition of 8.4% bicarbonate to reduce injection-related pain and improve analgesia duration. However, the clinical benefit of bicarbonate addition remains insufficiently supported by evidence and may increase preparation complexity and risk, including potential solution crystallization. The aim of the ROPIWA-2 trial is to investigate whether omission of bicarbonate from the local infiltration mixture is noninferior to bicarbonate addition with respect to early postoperative quality of recovery on postoperative day 1. We hypothesize that removing bicarbonate does not impair postoperative quality of recovery after ambulatory hand and foot surgery under WALANT. Expected benefits include confirmation of a simpler, ready-to-use anesthetic solution that is easier and safer to use, without reducing patient comfort or recovery. The expected risks are those normally associated with this type of procedure.

Hallux valgus surgery is known as a painful surgery. Qualitative pain management is the key to successful early recovery and rehabilitation. Popliteal sciatic nerve block is widely used but at risk of falling due to prolonged motor blockade and foot drop. Ankle block is recognized as a good regional anesthesia technique but requires five skin punctures. FIT block might be a good alternative, aiming to provide an optimal anesthetic block, good postoperative analgesia without motor blockade (calf muscles) and necessitating only two skin punctures. The purpose of this study is to describe the technique and the efficacy and safety of the FIT block for outpatient foot surgery
