Introduction: Distal radius fracture is very common, but few studies have shown its association with radial artery injury. We present two cases of distal radius fracture with radial artery injury.
Patient 1 : A 28-year-old woman sustained a distal radius fracture in a traffic accident. During surgery, the radial artery was found to be entrapped and thrombosed at the fracture site. The thrombosed segment was resected, and end-to-end anastomosis was performed under microscopy.
Patient 2 : A 69-year-old woman fell from standing height and sustained a distal radius fracture to her left wrist. During surgery, the radial artery was found to be completely lacerated at the fracture site. After stable fixation of the radius, the lacerated artery was repaired under a microscope.
Discussion : In both of these cases, the fracture line extended from the distal volar to the proximal dorsal end of the distal radius, which is an uncommon observation. The sharp edge of the proximal fracture segment caused laceration of the radial artery because of the high degree of fracture displacement. Thus, in similar fractures, injury of the radial artery must be suspected.
