Use of the Finite Element Method to Assess Impact of Current on Forearm and Wrist During an Electrical Accident

Using geometric primitives, a three dimensional finite element model has been developed to assess the pathway followed by electric current during an electrical accident assuming the entry point for the current was on one hand. Results indicate that the area where the risk of soft tissue injury is greatest is in the wrist region. Current entry on the palm or finger fronts was found to be more likely to yield injury to the median nerve than an entry point on the back of the hand. The lesser injury is theorized to result because of current shielding of the nerve by bone
