Positive Buerger’s Test
There is positive Buerger’s test when there is more than 1 to 2 minutes required for cyanosis or redness and refilling of the dorsal veins of the foot to occur. This sign could indicate lower extremity vascular compromise, peripheral vascular disease, atherosclerosis, chronic compartment syndrome.
It is possible for sciatic-like pain to be produced from lower extremity vascular disorders. The test aids in the differential diagnosis between vascular and neurogenic pain generators.
