The digital block of the first toe is a fundamental procedure in podiatric and forefoot surgery, and its success depends on precise anatomic knowledge and adequate anesthetic distribution. The inverted V digital block was developed as an alternative to traditional H and ring techniques in order to optimize anesthetic diffusion, reduce the number of punctures, and improve patient comfort. This article provides a detailed technical description of the inverted V approach and its anatomic rationale, supported by previously published prospective multicenter data demonstrating higher anesthetic efficacy and greater patient tolerance compared with the H block. The inverted V digital block represents a reproducible and efficient alternative for anesthesia of the first toe in surgical practice. Level of Evidence: Level 5.
