title: Biomechanical evaluation of the influence of an intramedullary pin on the stability of a feline ilial fracture model stabilized with a bone plate.
abstract: OBJECTIVE
  To compare the mechanical properties of feline ilial fractures stabilized with either a plate (P), or a plate and IM pin (P + P).
  
  
  METHODS
  Mechanical study.
  
  
  METHODS
  Cadaveric cat pelvii (n = 10).
  
  
  METHODS
  Feline ilial fractures (n = 20) stabilized with either P or P + P were subjected to 100 nondestructive load cycles, then loaded to failure. Deformation after cycling, yield load and displacement, stiffness and load at 2 mm of displacement were compared between groups.
  
  
  RESULTS
  There were no significant differences between groups for any of the parameters. Variability of data was much larger for the P + P group.
  
  
  CONCLUSIONS
  No biomechanical advantage was demonstrated. The P + P constructs were not significantly stronger than plates alone in this acutely loaded cadaveric model.
