Plain-English summary
Five cats suffering from severe constipation due to a narrowed pelvic canal were treated with a surgical procedure called triple pelvic osteotomy. This surgery involved widening the pelvic canal by repositioning the bones and securing them with screws. After the surgery, the cats showed an average improvement of 20% in the width of their pelvic canal, and none experienced any major complications or a return of their constipation during follow-up, which lasted from five months to a year. The procedure was effective and relatively simple, providing a good outcome for the cats.

Abstract
OBJECTIVE:  The aim of this study was to describe the technique and the clinical outcome of cats with obstipation as a result of pelvic canal narrowing, treated using an alternative triple pelvic osteotomy technique. METHODS:  Five cats with obstipation as a result of pelvic canal narrowing due to pelvic fracture malunion or secondary hyperparathyroidism were treated by triple pelvic osteotomy. After performing the iliac osteotomy and medial partial cortical debridement (4/5 cases), the pelvic canal was widened by moving the caudal fragment of the ilium to the lateral aspect of the cranial fragment. The iliac fragments were fixed by a 2.7-mm lag screw (5/5 cases) and an additional 2 Kirschner wires 0.8 mm (1/5 cases). RESULTS:  The radiographic examination immediately postoperatively and 8 weeks postoperatively showed a mean pelvic canal enlargement of 20% (range 7-38%). Minor complication occurred in one case; this resolved 15 days postoperatively without any treatment. Complications and recurrence of obstipation did not occur during the final follow-up, ranging between 5 months and 1 year in any of these cases. CLINICAL SIGNIFICANCE:  The use of lag screw fixed triple pelvic osteotomy resulted in widening of the pelvic canal and led to a satisfactory outcome with no major complications. This technique is fast, requires no expensive implants and it is relatively straightforward. Further cases are required to determine the success and complication risk of the procedure.
