Scoring of radiograph using RUST: (a) the presence of a fracture line with no callus formation (this is scored as 1), (b) the presence of a fracture line with soft callus formation (this is scored as 2), (c) bridging callus (this is scored as 3), and (d) complete bridging of the callus without a fracture line (this is scored as 4).
