Rolando fracture is best described as which?

Rolando fracture is best described as which?

• A. A comminuted intra-articular fracture of the base of the first metacarpal
• B. Non-displaced fracture of the base of the second metacarpal
• C. Simple fracture of the distal phalanx
• D. Non-displaced fracture of the base of the third metacarpal

Answer: (A)

Rolando fracture is a comminuted intra-articular fracture at the base of the first metacarpal (the thumb). The base involvement means the fracture extends into the joint surface, and the multiple fragments make it unstable, distinguishing it from simpler patterns. It’s the more complex variant of a Bennett fracture, which is a two-part intra-articular base fracture of the same bone. The other described injuries involve different digits or non-displaced distal phalanx fractures and do not fit this pattern.
