Proximal radial shaft fracture with rotational displacement on radiography

An anteroposterior view of the radius and ulna shows a fracture of the proximal radius (arrow) and an altered position of the bicipital tuberosity (arrowhead) when compared to the normal position of the bicipital tuberosity in this view (B, arrowhead). Image C is a lateral view of the proximal fracture of the radius (arrow), bicipital tuberosity, and the eccentric soft tissue swollen muscle mass (asterisk) compared to the normal (D) where there is a paucity of muscle mass in this location (asterisk). In this lateral projection, the altered position of the bicipital tuberosity in C (arrowhead) is not as well appreciated when compared to its position in the normal (D, arrowhead).
