To compare fracture healing in diaphyseal tibial fractures stabilized using either minimally invasive plate osteosynthesis (MIPO) or open reduction and internal fixation (ORIF).
Dogs in each group were matched for type of fracture, age and body weight. Stage of healing was measured blindly every four weeks postoperatively until complete healing. Outcome variables including fracture length, plate length, plate bridging ratio, plate working length, healing grading, and fracture reduction were compared between groups using the Mann-Whitney test. Significant difference was set at p <0.05.
Based on the definition of clinical union, at 30 days five out of eight dogs managed with MIPO had healed, while two of the eight of dogs managed with ORIF had healed. We did not find any significant differences in the other outcome measures. No complications were reported in the MIPO group whereas one major complication was reported in the ORIF group.
All dogs treated by MIPO healed rapidly without any complications, nevertheless the difference in radiographic healing between the two groups was not significant.
比较采用微创钢板接骨术（MIPO）或切开复位内固定术（ORIF）治疗的胫骨干骨折的骨折愈合情况。
每组犬的骨折类型、年龄和体重相匹配。术后每四周进行一次盲法测量愈合阶段，直至完全愈合。使用曼-惠特尼检验比较两组之间的结果变量，包括骨折长度、钢板长度、钢板桥接率、钢板工作长度、愈合分级和骨折复位情况。显著性差异设定为p<0.05。
根据临床愈合的定义，在30天时，采用MIPO治疗的8只犬中有5只愈合，而采用ORIF治疗的8只犬中有2只愈合。我们在其他结果指标中未发现任何显著差异。MIPO组未报告任何并发症，而ORIF组报告了1例主要并发症。
所有接受MIPO治疗的犬均快速愈合且无任何并发症，然而两组之间的影像学愈合差异并不显著。
