Vascular injuries are an extremely rare complication of clavicle osteosynthesis, though several cases are reported in the literature. Cadaver studies have established recommended safe lengths for clavicle screws based on precise measurements of bone thickness and distance from subjacent neurovascular structures. We present the case of a 27-year-old female who underwent orthopedic plate and screw fixation of a clavicle fracture and subsequently sustained iatrogenic vascular injury from one of the screws. This necessitated endovascular repair and orthopedic revision. This case underscores the importance of selecting appropriate screws based on available imaging. Keywords: Proud screw pseudoaneurysm, Iatrogenic vascular injury
