Distal ulnar fractures

Last revised by Bahman Rasuli on 26 Feb 2021

Distal ulnar fractures are common and usually occur with a concurrent distal radius fracture.


Isolated fractures occur as a result of direct force to the ulna. Fractures associated with radius fractures usually occur as the result of a fall on an outstretched arm.

Distal ulnar fractures are divided into two groups:

  1.  isolated:
  2. associated with distal radius fractures: Frykman classification of distal radial fractures
