Cadaveric investigation about the spread of peritibial fascial infiltration block

Recently, Ekinci et al. defined a novel lower extremity fascial plane block named peritibial fascial infiltration block (PFIB). They performed PFIB for analgesia management after tibia fracture surgery and reported successful pain control during the postoperative period.1 Following the description of PFIB by Ekinci et al., Altiparmak et al. performed PFIB with a saphenous nerve block (SNB) for a patient who underwent a bimalleolar fracture of the ankle.2 They combined two techniques for the reason that SN is responsible for the sensorial innervation of the lower leg. Due to fascial plane blocks being volume-related applications,3 we decided to investigate the spread of PFIB with different volumes in this cadaveric study. This study was approved by the Istanbul Medipol University Ethics and Research Committee (Decision no. 35; 06.01.2022).
