What paper described intramedullary supply of feline tibia
compared to dogs and what did it show? -
correct answer ✅Dugat et al VCOT 2011
-Intramedullary arterial supply of feline tibia compared to canine,
feline nutrient artery diameter was greater than dogs but dogs had
a greater number of arching vessels (arborization), lack of
branching vessels when compared to dogs could explain at least in
part why non-union or delayed tibial healing is so common
Opinion on pancarpal arthrodesis in cats -
correct answer ✅-Controversial
-prognosis can be good as long as you follow the principles
-completely remove cartilage, anatomic standing angle, cancellous
bone graft, appropriate fixation (usually a plate)
