In the distal third of the tibia, the anterior tibial artery runs close to the anterolateral surface of the tibial cortex. In a clinical situation, without vascular evaluation, injury or entrapment of the anterior tibial artery is difficult to detect. Because, an intact dorsalis pedis pulse is supplied with the collateral vessels of the posterior tibial artery. An entrapped anterior tibial artery can be injured during closed reduction in an emergency room or open reduction and internal fixation in the operating room. Care must be taken to prevent iatrogenic anterior tibial artery. In this case, an entrapped anterior tibial artery was observed in a simple radiograph and computed tomograph without contrast media for the vessel. We report on a rare case of calcified anterior tibial artery entrapment in a distal tibial fracture.
