Objective The aim of this study was to compare the frequency of implant failure and the extent of pelvic canal narrowing associated with the fixation of ilial fractures in cats with a single veterinary cuttable plate (SLP) or double veterinary cuttable plates (DLP) applied to the lateral surface of the ilium.

Study Design Radiographic evaluation of feline ilial fractures plated laterally using SLP or DLP. Pelvic canal narrowing directly postoperatively and at 6 weeks follow-up was objectively measured using the sacral index (SI). Radiographs were evaluated for implant failure and fracture healing.

Results Seventy-seven cats satisfied the inclusion criteria. Twenty-nine fractures were treated with a SLP and 48 with DLP. Implant failure occurred significantly more (p = 0.001) in the SLP group (14/29) compared with the DLP group (6/48). Follow-up SI was significantly different between the two groups (p = 0.048, SLP median: 1.0 range: 0.83–2.4, DLP median: 0.98; range: 0.76–1.45). Median change in SI was −0.04 (range: −1.4–0.05) in the SLP group and 0.0 (range: −0.23–0.23) in the DLP group. This difference was significantly different (p = 0.031).

Conclusion DLP leads to significantly less implant failure and significantly less pelvic canal narrowing compared with SLP. This difference in pelvic canal narrowing was small and the clinical relevance remains unclear.

目的 本研究的目的是比较植入失败的频率和与固定猫髂骨骨折相关的骨盆管变窄的程度，其中单个兽医可切割钢板 (SLP) 或双兽医可切割钢板 (DLP) 应用于猫的髂骨骨折。髂骨的外侧面。

研究设计 使用 SLP 或 DLP 横向电镀的猫髂骨骨折的放射照相评估。使用骶骨指数 (SI) 客观测量术后和 6 周随访时盆腔管直接变窄。对射线照片进行了植入失败和骨折愈合的评估。

结果 77 只猫满足纳入标准。29 处骨折采用 SLP 治疗，48 处骨折采用 DLP 治疗。 与 DLP 组 (6/48) 相比，SLP 组 (14/29) 的种植体失败发生率明显更高 ( p = 0.001)。两组之间的随访 SI 有显着差异（p  = 0.048，SLP 中位数：1.0，范围：0.83-2.4，DLP 中位数：0.98；范围：0.76-1.45）。SLP 组的 SI 变化中位数为 -0.04（范围：-1.4-0.05），DLP 组为 0.0（范围：-0.23-0.23）。这种差异有显着差异（p  = 0.031）。

结论 与 SLP 相比，DLP 显着减少种植体失败和显着减少骨盆管狭窄。骨盆管狭窄的这种差异很小，临床相关性仍不清楚。
