holy f! dude, how old are you? you cant really classify this as a pathological fracture though - you were carrying 2 other people! but a femur should NOT fracture like that unless there was an underlying weakening process going on. have them check for any tumours like DJ... suggested. like a bone scan maybe? ask about going for a bone desity scan as well - men get osteoporosis too. cant really see anything funny on the xrays other than the terribly fractured and displaced femur (and then the pin). good grief that must be sore. condolences ++. hope you get well soon.
