A fracture line passes to the articular surface of the radius.
Note the radial styloid fracture.
The lateral view shows the fracture with palmar (volar) displacement.
Note: Some would loosely call this a 'Colles' fracture. Others may call this a 'Smith's fracture' or a 'volar Barton's fracture'.
Use of eponyms can cause confusion; an accurate description is more informative and avoids misinterpretation.
