Fractured ulna bone and fixation. X-rays of a broken ulna bone in a patient's left arm before (left) and after (right) surgery to treat the fracture with a fixation plate. This fracture is at the distal (wrist) end of the shaft of the ulna. The surgery carried out was an open reduction and internal fixation. Screws and a metal plate were implanted across the fracture to hold the broken bone in place, allowing it to heal in the correct alignment.
