A case of isolated post-traumatic sciatic nerve contusion is reported, sustained after direct blunt trauma to the region of the buttock after a fall. Evaluation of this nerve injury not only included an EMG/ NCS, but also confirmatory evidence was obtained using the Minor's iodine-starch test to detect disturbances of sweat secretion. This case of sciatic nerve contusion responded to stimulator-guided local steroid injections. Cross-sectional anatomy of the sciatic nerve and various etiologies of sciatic nerve neuropathy is revisited.
