A 7-year-old neutered male Korean domestic short-haired cat was referred to our clinic to treat constipationwhich had persisted for 6 months. The rectal examination revealed narrowing of the right lateral portion of the pelviccanal. A reduced pelvic canal diameter by pelvic fracture malunion was revealed on radiography. The pelvic canaldiameter ratio measured from preoperative was 0.68. Based on rectal and radiographic examinations, constipation causedby pelvic canal narrowing was confirmed. Pelvic symphyseal distraction-osteotomy and iliac wedge osteotomy wereperformed. An iliac osteotomy of the ilium was performed to ease the pelvic symphyseal distraction. After the symphysiswas split longitudinally, pelvic symphyseal distraction was maintained by using a spacer made of poly-methylmethacrylate. The osteotomy of the ilium was fixed using a bone plate and screws. Increased pelvic canal diameterwas confirmed on post-operative radiography and the postoperative pelvic canal diameter ratio was 0.91. The patientreceived antibiotics, NSAIDs, crystalloids and Lactulose for post-operative care. The cat recovered normal defecationabilities and did not have constipation at one week postoperatively. No episodes of constipation persisting longer than6 months have been reported by owners in previous studies. Pelvic symphyseal distraction osteotomy and iliac wedgeosteotomy may prove to be a useful surgical procedure to treat pelvic canal stenosis that is caused by pelvic fracturemalunion.
