Introduction. Arterial damage associated with musculoskeletal injuries at room conditions is very common. Aim. It is worth remembering that examining a patient who has suffered an accident with a broken bone or traumatic joint dislocation may be accompanied by vascular damage. A dislocation or fracture often masks damage to the artery. Description of the case. In this paper, a 20-year-old patient being a passenger suffered upper right limb trauma in a car accident. Conclusion. The effects of vascular injuries appear only after a few hours after setting the fracture. It is not known then whether the artery was damaged at the same time with the fracture, whether the injury occurred during the adjustment, or whether the ischemia is finally the result of the pressure exerted by too tight plaster casts.
