Case Discussion
The volar tilt, or palmar 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).
It is a useful radiographic measurement in the assessment of distal radius fractures.
