Abstract
Objective— To (1) report a technique for repair of feline ilial fractures using a dorsally applied bone plate and (2) compare outcome with cats treated by a lateral plate.Study Design— Prospective study.Animals— Cats (n=10) with iliac fractures.Methods— Cats with ilial fractures (January 2005–December 2006) were treated by application of a dorsally applied bone plate. Immediate postoperative radiographs were compared with those taken 4–6 weeks later to assess screw loosening, screw purchase, and pelvic canal narrowing. Owners were contacted for medium‐term (>3 month) follow‐up. Data were compared with a report of outcome after lateral plating (LP) in 21 cats.Results— Mean (± SD) screw purchase (89 ± 11 mm) was significantly greater (P<.01) with a dorsal plate compared with a lateral plate (33 ± 8 mm). Significantly more screws (P<.01) were used with a dorsal plate (median, 7) compared with a lateral plate (median, 6). Significantly less postoperative pelvic canal narrowing developed in the dorsal plating group between postoperative and 4–6‐week follow‐up radiography compared with the LP group (2% versus 15%, P<.01).Conclusion— Dorsal plating of feline ilial fractures results in significantly less screw loosening and pelvic canal narrowing at 4–6 weeks after surgery compared with LP.Clinical Relevance— Dorsal plating of feline iliac fractures may reduce complications associated with pelvic canal narrowing such as constipation and megacolon.
