title: Use of a caudoventral-craniodorsal oblique radiographic view made at 45° to the frontal plane to evaluate the pectoral girdle in raptors.
abstract: OBJECTIVE
  To evaluate use of a caudoventral-craniodorsal oblique radiographic view made at 45° to the frontal plane (H view) for assessment of the pectoral (thoracic) girdle in raptors.
  
  
  METHODS
  Retrospective cross-sectional analysis.
  
  
  METHODS
  24 raptors suspected to have a fracture of the thoracic girdle.
  
  
  METHODS
  Standard ventrodorsal and H views were obtained for all birds. Radiographs were evaluated twice by a radiologist blinded to the final diagnosis, with each view first evaluated independently and views then evaluated in combination. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated, with results of surgery or necropsy used as the gold standard.
  
  
  RESULTS
  9 birds had thoracic girdle fractures; fractures were correctly identified in 8 of these 9 birds on the ventrodorsal view alone, 7 of these 9 birds on the H view alone, and all 9 birds on the 2 views in combination. Fifteen birds did not have thoracic girdle fractures; radiographs were correctly classified in 12 of these 15 birds when the ventrodorsal view was evaluated alone, all 15 birds when the H view was evaluated alone, and 14 of these 15 birds when the 2 views were evaluated in combination.
  
  
  CONCLUSIONS
  Results suggested that the H view or the addition of the H view to the VD view could be useful in raptors suspected to have fractures of the thoracic girdle. Agreement with the gold standard (ie, fracture present or absent) was higher with the H view and combination of views than with the ventrodorsal view alone.
