title: Use of a virtual 3D software for planning of tibial plateau fracture reconstruction.
abstract: OBJECTIVE
  Anatomical reconstruction of tibial plateau fractures is necessary to prevent pain, axial malalignment, knee join instability and posttraumatic arthritis. Computed tomography (CT) with 3D reconstruction is helpful in the accurate preoperative evaluation and reduction planning of the fracture site. The aim of this study was to describe the application of a virtual 3D reconstruction and segmentation software in the preoperative planning of tibial plateau fractures.
  
  
  METHODS
  CT scans of five tibial plateau fractures were preoperatively evaluated using the 3D planning software. Manual colour-coded segmentation was performed. The amount of time required for each planning session was recorded.
  
  
  RESULTS
  Successful 3D reconstruction and segmentation was achieved in all cases. The mean time required for 3D virtual planning was 174.8 min (range 69-124 min). The mean time required for 3D virtual planning of B-type fractures was 96.5 min (range 69-124 min; SD=38.891 min; CI=349.421). The mean time required for planning of C-type fractures was 227 min (range 167-294 min; SD=63.789 min; CI=158.460) (Table 1).
  
  
  CONCLUSIONS
  Successful segmentation was achieved in all cases. The 3D planning capabilities of this software may be a valuable tool for surgeons in learning about the nature of the injury in tibial plateau fracture cases and in formulating an appropriate surgical plan. However, the time requirement for the 3D reconstruction and segmentation analysis may be a current deterrent for its use in the clinical setting.
