Radial head fracture Type 3 is characterized by what?

Radial head fracture Type 3 is characterized by what?

• A. Non-displaced.
• B. Displaced.
• C. Comminuted.
• D. Associated with elbow dislocation.

Answer: (C)

Type III radial head fractures are defined by comminution—the radial head breaks into multiple fragments. This pattern stems from severe trauma and means the articular surface is often disrupted and the elbow joint may be unstable. This distinguishes it from nondisplaced fractures (Type I) and from a single displaced fragment (Type II). It’s not primarily defined by dislocation (that description fits fracture-dislocation injuries in other classifications), so the hallmark of Type III is the several fragments rather than a single moved piece or a simple, intact head.
