title: [Radiological comparison between two procedures for ventral spondylodesis: autologous iliac crest bone graft vs bovine bone graft].
abstract: BACKGROUND
  The objective of this study was the radiological evaluation of osseous integration of autologous iliac crest graft and bovine bone graft after spondylodesis based on a standardized score.
  
  
  METHODS
  Spondylodesis was performed on 18 sheep, divided into 2 groups, 1 with an autologous iliac crest graft and the other with a bovine bone graft. Computed tomography was performed 12 and 24 weeks postoperatively. The osseous integration was assessed by the Tübinger Score.
  
  
  RESULTS
  The evaluation of the CT scans demonstrated a significantly better osseous integration of the autologous iliac crest graft compared to the bovine bone graft.
  
  
  CONCLUSIONS
  Based on our results, the bovine bone graft as a transplant for spondylodesis is inadvisable.
