Fracture of the radial styloid process with scapholunate dissociation

Case contributed by Bálint Botz


Sustained a FOOSH, injured the left wrist.

Patient Data

Age: 65 years
Gender: Male
  • Depressed radial styloid process fracture, increased SL distance and negative ulnar variance redemonstrated. 
  • Small, sclerotic foci adjacent to the scaphoid likely represent degenerative changes rather then acute trauma.  
  • Small bone island in the capitate with no clinical significance. 

Status post ORIF with nail and volar locking plate, radiograph taken in cast. Increased SL distance and negative ulnar variance redemonstrated. 

Case Discussion

Scapholunate interval and ulnar variance should be carefully assessed on every trauma wrist exam taken post FOOSH.
