To determine the influence of plating systems on the clinical outcomes in dogs treated for ilial fractures.
Retrospective study.
Fifty-nine dogs (63 hemipelves).
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.
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.
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.
Surgeons should consider repairing ilial body fractures in dogs with LPS to reduce the risk of short-term implant failure.
确定接骨板系统对接受治疗的犬股骨干骨折临床结果的影响。
回顾性研究。
59 只狗（63 个半骨盆）。
回顾 2003 年至 2019 年期间在爱荷华州立大学就诊的犬股骨干骨折的放射照片和病历。在骨折复位后，使用锁定接骨板系统（LPS）或非锁定接骨板系统（NLS）固定骨折。记录围手术期、长期并发症和随访数据。使用逻辑回归和线性回归分析分别比较了植入物失败和骨盆塌陷的频率。对单变量检验有统计学意义的情况，进行多变量分析以确定具有统计学差异的类别。
在 63 个半骨盆中，分别使用 LPS 和 NLS 植入物 25/63 和 38/63。中位随访时间为 8 周（3-624 周）。在 63 例骨折修复中，有 18 例（29%）发生植入物失败，其中 17 例为 NLS，1 例为 LPS。在 5 例植入物失败的病例中均建议进行翻修手术，所有病例均为 NLS。使用 NLS 固定骨折时，植入物失败的可能性更高（p=0.0056）。评估的所有其他变量似乎都没有影响结果测量。
对接受治疗的犬股骨干骨折结果影响最大的变量是固定方法（NLS 与 LPS）。使用 NLS 修复的骨折发生短期植入物失败的可能性是使用 LPS 修复的近 20 倍。
外科医生应考虑在犬股骨干骨折中使用 LPS 修复，以降低短期植入物失败的风险。
