Mason classification is used for fractures of which bone?

• A. Radial head
• B. Scaphoid
• C. Distal radius
• D. Humerus

Answer: (A)

Mason classification focuses on fractures of the radial head, describing the pattern and how displaced the fragments are to guide treatment. It ranges from nondisplaced fractures to displaced marginal fractures, then to comminuted fractures, and finally to fractures with elbow dislocation, with each pattern implying different management needs. This system was developed specifically for radial head injuries, so it’s the standard way to categorize fractures of that bone. The other bones listed have their own separate classification schemes, so Mason’s system wouldn’t be used to categorize those fractures.
