If there’s visible angulation, and you’ve been trained in wilderness first aid, Tarter recommends attempting to put the extremity back in its normal anatomical alignment. Doing so will most likely improve circulation, sensation, and motion. If that is the case, you can make your way to civilization safely and calmly. But if you can’t be certain the bone is broken, you lack training, or straightening the limb doesn’t improve circulation and sensation, emergency evacuation becomes the absolute priority. Leave this procedure to the trained professionals.
