Three acute peripheral arterial occlusions occurred 60, 38 and 12 years after imperfect reduction of fractures. In two cases the embolus originated from an aneurysm induced by an hypertrophic callus of the clavicle. In the third case, acute thrombosis appeared as the consequence of leg arteries compression by a tibial osteomyelitic callus. Arterial reconstruction in the two first cases and thrombolysis in the third case were associated to surgical treatment of the causal injuries and were successful.
