BACKGROUND: In all, 68% of all lower limb amputees experience residual limb pain. More than 95% of all lower limb amputations in developed countries are due to peripheral artery occlusive disease in combination with diabetes mellitus. Therefore, claudication, which is one of the most common manifestations of peripheral artery occlusive disease, should be taken into consideration in making a differential diagnosis of residual limb pain. Case description and methods: We present a case study of a 60-year-old diabetic patient who underwent a transfemoral amputation due to peripheral artery occlusive disease and who experiences residual limb pain...
