Mason classification is used for fractures of which bone?

• A. Radial head
• B. Scaphoid
• C. Distal radius
• D. Humeral shaft

Answer: (A)

Mason classification is a system for grading fractures of the radial head based on displacement and joint involvement, and it directly guides treatment decisions. The radial head is the bone this scheme focuses on, helping determine whether a fracture can be managed nonoperatively, needs surgical fixation, or requires excision or replacement in more complex cases. Other bones have their own separate classification schemes (for example, the scaphoid uses Herbert, the distal radius uses Frykman or AO classifications, and the humeral shaft has Winquist-Hansen), so Mason classification is specific to radial head injuries. The types range from nondisplaced or minimally displaced fractures to marginally displaced, comminuted, and fractures associated with elbow dislocation, with management escalating accordingly.
