Depending upon the severity of the pelvic fractures, the conservative management can lead to complications such as compromise of the pelvic inlet or outlet, degenerative joint disease, and a non-functional limb.
The purpose of this report was to describe the surgical procedures used to treat pelvic canal narrowing.
Two male crossbred dogs were admitted due to severe constipation secondary to pelvic fracture managed conservatively. The dogs had been treated with enemas, and laxatives without success. Digital rectal examination and survey radiographs confirmed a pelvic stenosis of more than 60% due to chronic malunion fractures. In both cases, contrast radiography revealed a narrowing of the descending colon at the level of fracture malunion. The surgical procedures in both cases included a celiotomy and removal of the bone fragments displaced medially into the pelvic canal using bone chisel and hammer, and gouge. Excision of the femoral head that was located into the pelvic canal was necessary in a dog. All procedures were done via pelvic canal.
The dogs did not show episodes of obstipation after the surgery, and limb function was maintained.
In conclusion, removal of the bone fragments displaced via pelvic canal is an option to treat pelvic stenosis.
