A 23-year-old male presents to you in the A&E department having fallen off his bike. He landed on his outstretched left arm, which is now very painful and has a mild dinner fork deformity. He says he felt a ‘crack’ when he landed followed by immediate severe pain and inability to move the wrist. On examination, the sensation and blood supply to his palm are intact. He is sent for an x ray of the wrist which is shown below:
