1.I could see the fracture is healing well in the second xray 2.It is safe for you to travel in a car and walking with elbow crutches with weight bearing as tolerated by you. It is better to avoid stairs. It is better that you dont stand for more that 15 mins continously and take intermittent breaks by sitting and keeping your leg up 3.In any open fracture, there is a risk of infection. But I dont think you would be having any signs of infection like pain,swelling,redness,warmth at fracture site based on your xrays 4.You can slow wean off your crutches like the following. Double crutches - 2 weeks Single crutch - in opposite hand - 2 weeks Single crutch only outdoors - 2 weeks Walk without support
