Rolando, Bennett…which one?

January 5, 2013

Eponyms, Hand XR, Orthopedics, Trauma, XR

This is a patient with pain in the thumb after punching another person:

MC Thumb fx 2MC Thumb fx 1

Fractures of the base of the 1st (thumb) metacarpal are highly morbid injuries.  Most of these should be operative but many end up with severe arthritis of the MCP joint despite optimal therapy.  The thumb is a very important functional joint especially on the dominant hand, as in this patient.

Radiographically there are several eponym fractures for the base of the 1st metacarpal:  Rolando and Bennett are the most widely discussed eponym fractures.

Which one is this (if either)?

Answer to follow.
