Presentation
Mechanical fall onto left side. Concurrent neck of left femur fracture also.
Patient Data
Comminuted fractures of the distal radius with dorsal angulation of the fragments (i.e. a Colles fracture). Acute fracture through the head of the ulna.
OA of the STT articulation.
Incidental note of a short fifth metacarpal. Unfortunately no previous imaging available.
Diffuse osteopenia.
Case Discussion
Fractures through the distal ulna (other than of the base of the ulnar styloid) are relatively uncommon. In a study published in 2013, only 11 patients of 512 consecutive cases of distal radius fracture sustained a simultaneous distal ulna fracture (~2% cases) 1.
