title: Revisit of Broden's view for intraarticular calcaneal fracture.
abstract: BACKGROUND
  This study was performed to investigate the relationship between coronal computed tomography (CT) and Broden's view in terms of location of the fracture line and fracture pattern.
  
  
  METHODS
  Forty-five feet of 45 patients with intraarticular calcaneal fractures were evaluated. The mean age of the patients was 46.3 years (standard deviation, 18.1; range, 15 to 80 years), and there were 34 men and 11 women. The Broden's views were acquired using the ray sum projection, reviewed, and correlated with the coronal CT image to determine the location of the fracture on the posterior facet and fracture pattern described by the Sanders classification. The quantified location of the fracture line was defined as the distance between the medial margin of posterior facet and the fracture line divided by the whole length of the posterior facet, which was expressed as a percentage.
  
  
  RESULTS
  The fracture line on the Broden's view was positioned at 22.3% (standard deviation, 29.6) laterally compared to that on coronal CT (p < 0.01). Although all cases showed posterior facet involvement on the CT scan, the fracture line was positioned lateral to the posterior facet in 6 cases (13.3%) in the Broden's view. The coronal CT and Broden's view showed a low level of agreement in the fracture pattern according to the Sanders classification, with kappa values of 0.23.
  
  
  CONCLUSIONS
  Surgeons should consider that the fracture line on the Broden's view shows positioning laterally compared to coronal CT and they should consider that the fracture line at the lateral to posterior facet on the Broden's view might be an intraarticular fracture line. There are some limitations when applying the Sanders classification with the Broden's view.
