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.

血管损伤是锁骨接骨术中极为罕见的并发症，尽管文献中有多例相关报道。尸体研究已根据对骨厚度以及与下方神经血管结构距离的精确测量，确定了锁骨螺钉的推荐安全长度。我们报告一例27岁女性病例，该患者接受了锁骨骨折的接骨板和螺钉固定，随后其中一枚螺钉导致了医源性血管损伤。这需要进行血管内修复和骨科翻修。该病例强调了根据现有影像选择合适螺钉的重要性。
