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.
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.
Seventy-seven cats satisfied the inclusion criteria. Twenty-nine fractures were treated with a SLP and 48 with DLP. Implant failure occurred significantly more ( = 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 ( = 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 to 0.05) in the SLP group and 0.0 (range: -0.23 to 0.23) in the DLP group. This difference was significantly different ( = 0.031).
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.
本研究旨在比较单兽医可切割板(SLP)或双兽医可切割板(DLP)固定猫髂骨骨折的植入物失败频率和骨盆管狭窄程度。
对侧髂骨用 SLP 或 DLP 行板固定的猫髂骨骨折的影像学评估。术后即刻和 6 周随访时,采用骶骨指数(SI)客观测量骨盆管狭窄程度。评估影像学上的植入物失败和骨折愈合情况。
77 只猫符合纳入标准。29 例骨折采用 SLP 治疗,48 例采用 DLP 治疗。SLP 组(14/29)的植入物失败发生率明显高于 DLP 组(6/48)( = 0.001)。两组的随访 SI 差异有统计学意义( = 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 中位数变化为-0.04(范围:-1.4 至 0.05),DLP 组为 0.0(范围:-0.23 至 0.23)。两组之间的差异有统计学意义( = 0.031)。
与 SLP 相比,DLP 导致的植入物失败发生率显著降低,骨盆管狭窄程度显著降低。这种骨盆管狭窄程度的差异较小,临床相关性尚不清楚。
