The volar tilt is assessed on the lateral radiograph of the wrist, it corresponds to the angle formed by a line drawn perpendicular to the axis of the radial shaft, and a line that passes through the tips of the dorsal and volar rims (i.e. along the radius articular surface) Normal is 7-15 degreesBONES     CARTILAGE SOFT TISSUES COLLES FRACTURE     BARTONS FRACTURE: INTRAARTICULAR DISTAL RADIUS FRACTURE
