Case: Pelvic widening in a cat and in a dog, to manage constipation after non-surgically managed pelvic fractures
21st January 2014
Chumsley presented with a severely narrowed pelvic canal after a road traffic accident 4-5 weeks before, and this was causing him difficulty in defaecating. It was likely that this would lead to progressive constipation and ultimately that causes a condition called megacolon which usually requires the surgical removal of the colon, serious procedure. The fracture was difficult to realign, and the major nerve to the hind limb was right in the way. For reasons that we struggle to explain, Chumsley seemed unable to urinate properly for 3 weeks or so post-operatively. The owner had financial constraints, and we helped them out by hospitalising Chumsley for free for this time. He stayed with us in the hospital in the week, and went home with whoever of Andy of Jon was on call for the weekend, so that his bladder could be kept empty. Once urinary function had normalised, Chumsley went home again and he is doing very well.
Rosie, a Yorkshire terrier had sustained a pelvic fracture well over a year before, before the current owner had had her, and this had led to chronic and progressive constipation. The pelvis was greatly narrowed. We cut the pelvis, realigned it (which created a gap in the bone) and fixed the pelvis in plate with a locking plate. Rosie was not a cooperative patient! She needed a couple of enemas to get her going, but within 2-3 weeks of surgery, she was defaecating without problem, and walking well on the leg. We doubt that the gap will ever bridge but for a small sedentary family pet, the functional outcome was very satisfactory.
