title: MR imaging of ulnocarpal impaction after fracture of the distal radius.
abstract: OBJECTIVE
  The purpose of our study was to evaluate the incidence of ulnocarpal impaction after distal radius fracture using MR imaging and to correlate imaging findings with those of radiography and clinical findings.
  
  
  CONCLUSIONS
  Ulnocarpal impaction is a common finding after distal radius fracture. MR imaging can detect characteristic bone marrow changes of the lunate early after the trauma. A significant correlation exists between MR imaging findings and the extent of posttraumatic ulnar variance and pain levels.
