Objective: To determine the influence of plating systems on the clinical outcomes in dogs treated for ilial fractures.
Design: Retrospective study.
Animals: Fifty‐nine dogs (63 hemipelves).
Methods: Radiographs and medical records of dogs with ilial fractures presented to Iowa State University between 2003 and 2019 were reviewed. After fracture reduction, fractures were fixed with a locking plate system (LPS) or non‐locking plate system (NLS). Perioperative, long‐term complications, and follow‐up data were recorded. The frequency of implant failure and pelvic collapse were compared using a logistic and linear regression analysis, respectively. Where the univariate test was statistically significant, a multivariate analysis across categories was performed to identify statistically different categories.
Results: LPS and NLS implants were used in 25/63 and 38/63 hemipelves, respectively. Median follow‐up time was 8 weeks (3–624 weeks). Implant failure occurred in 18/63 (29%) of fracture repairs, consisting of 17 with NLS and 1 with LPS. Revision surgery was recommended in five cases of implant failure, all with NLS. The probability of implant failure was higher when fractures were fixed with NLS (p = .0056). All other variables evaluated did not seem to influence outcome measures.
Conclusion: The variable with the most influence on the outcomes of dogs treated for ilial fractures consisted of the fixation method (NLS vs. LPS). Fractures repaired with NLS were nearly 20 times more likely to fail than those repaired with LPS.
Clinical Relevance: Surgeons should consider repairing ilial body fractures in dogs with LPS to reduce the risk of short‐term implant failure.
