This cadaveric study aimed to investigate the anatomical distribution of local anesthetic by evaluate its dissemination on fractured and non-fractured sides. The primary outcome was the distribution pattern of dye as visualised by CT imaging and confirmed by anatomical dissection.  \nMethods Cadaveric study. Single-centre study conducted in the Department of Anatomy Two formalin-fixed female cadavers aged 89 and 65 years, with no prior thoracic interventions.  \nBilateral deep serratus anterior plane blocks were performed under ultrasound guidance using methylene blue and contrast solution, following controlled unilateral rib fractures.  \nConclusions Both cadavers had anterolateral rib fractures. In the first cadaver, dye spread was observed toward thepleura but did not stain nerves. Dissemination was restricted due to a breast mass and thickened fascia. In the second cadaver, pleural penetration of the dye occurred on the fractured side, while the intact side showed no dye presence. Lateral cutaneous branch of the intercostal nerve, thoracodorsal nerve and long thoracic nerves staining occurred only on the non-fractured side. CT and dissection results were concordant.  \nConclusions The predictability of serratus anterior plane block efficacy may be compromised in the setting of rib fractures associated with blunt trauma due to variability in drug distribution. Given the small number of formal in-fixed cadavers used, these findings should be interpreted as preliminary anatomical observations requiring validation in fresh or Thiel-embalmed models.  \nKeywords Rib fractures, Nerve block, Cadaver, Ultrasonography, Tomography, X-Ray computed, Pain management, Regional anesthesia, Intensive care units  \n*Correspondence:  \nVol kan Alparslan  \n[vol kan.al parslan@kocaeli.edu.tr](vol kan.al parslan@kocaeli.edu.tr)  \n1Department of Anaesthesiology and Reanimation, Faculty of Medicine, Kocaeli University, Kocaeli, Turkey  \n2Department of Anatomy, Faculty of Medicine, Kocaeli University, Kocaeli, Turkey  \n3Department of Cardiovascular Surgery, Faculty of Medicine, Kocaeli University, Kocaeli, Turkey  \n4Department of Radiology, Faculty of Medicine, Kocaeli University, Kocaeli, Turkey  \n5Kocaeli University Faculty of Medicine, Umuttepe/Izmit 41180, Turkey  \n© The Author(s) 2025.
