QuestionChoice
Scaphoid fractures typically present with pain in the anatomical snuffbox and are less likely to cause dorsal displacement of the distal radius. The anatomical snuffbox is a depression on the thumb side of the wrist.

QuestionChoice
Monteggia fractures involve a fracture of the proximal ulna and dislocation of the radial head. They occur at the elbow, not the wrist, and are not consistent with the presentation described.

QuestionChoice
Galeazzi fractures involve a fracture of the distal radius and dislocation of the distal ulna. Whilst it includes a distal radius fracture, the displacement pattern and location described in this question are not consistent with a Galeazzi fracture.

A 45-year-old patient presents with a history of a fall onto an outstretched hand and presents with a characteristic deformity of the wrist. On physical examination, there is dorsal displacement of the distal radius.

Based on these findings, which of the following is the most likely diagnosis for this wrist injury?
