Three-Dimensional Imaging of Displaced Intra-articular Calcaneal Fractures Correlates With the Perioperative Diagnosis
Background: Intra-articular calcaneal fractures are complex injuries, and CT imaging has become the standard imaging in the preoperative assessment. Most classifications of these fractures are CT-based but have been associated with limited interobserver agreement. Three-dimensional imaging has becom...

Background: Intra-articular calcaneal fractures are complex injuries, and CT imaging has become the standard imaging in the preoperative assessment. Most classifications of these fractures are CT-based but have been associated with limited interobserver agreement. Three-dimensional imaging has become widely available and may give a better perspective but often with 1 image only. There is not much evidence of the added value of this imaging, compared with the CT imaging. Methods: Eight experienced trauma surgeons assessed 28 different intra-articular calcaneal fractures, on conventional radiology (CR), CT, and 3-D imaging. All had extensive experience in the diagnosis and treatment of this difficult injury. The main questions concerned Sanders classification, the severity of the injury and the difficulty of the operative procedure, choice of approach, and choice of procedure. Results: The classical 2-D CT imaging of the fractures were associated with a higher Sanders classification ranking, compared with the 3-D imaging scores. However, the interobserver agreement, as measured by the Fleiss kappa, was low for all 3 imaging modalities.
