The Minimally Invasive Reduction Instrumentation System (MIRIS) was utilized to facilitate minimally invasive plate osteosynthesis (MIPO) of distal limb diaphyseal comminuted fractures (2 crural, 1 antebrachial) in three dogs. The MIRIS facilitated efficient MIPO in all three fractures. Radial and tibial lengths were restored within 2% of the length of the intact bone and postoperative frontal and sagittal plane angulation were within 3° of the normal contralateral limb for each of the fractures. Fixation failed in one of the tibial fractures when the plates bent a week following surgery. The implants were removed and the fracture was restabilized via MIPO facilitated by the MIRIS. Inappropriate implant selection was considered the primary reason for implant failure. All three fractures achieved union by 10 weeks following surgery. The dog that underwent revision surgery developed a surgical site infection 5 months following revision surgery, which necessitated implant removal. All three dogs had excellent limb function at the time of the final evaluation. This system resulted in reductions that were near anatomic, with acceptable restoration of length and alignment and excellent limb function.
采用微创复位器械系统（MIRIS）对3只犬的四肢骨干粉碎性骨折（2处小腿骨折，1处前臂骨折）进行微创钢板接骨术（MIPO）。MIRIS使所有3处骨折均顺利完成了高效的MIPO。桡骨和胫骨长度恢复至完整骨骼长度的2%以内，各骨折术后额状面和矢状面成角与对侧正常肢体相差在3°以内。1例胫骨骨折术后1周钢板弯曲，固定失败。取出植入物，通过MIRIS辅助的MIPO使骨折重新获得稳定。植入物选择不当被认为是植入物失败的主要原因。所有3处骨折在术后10周均实现愈合。接受翻修手术的犬在翻修手术后5个月发生手术部位感染，需要取出植入物。在最终评估时，所有3只犬的肢体功能均良好。该系统实现了接近解剖复位，长度和对线恢复可接受，肢体功能良好。
