Pediatric fractures are relatively common in dogs, and several treatment options exist, particularly for fractures in the distal extremities. Regardless of the choice of treatment, the overall goal is rapid restoration and excellent long-term functional recovery, with minimal discomfort and morbidity during healing. This case series aims to report the long-term outcome after minimally invasive percutaneous elastic plate osteosynthesis (MIPEPO) in the treatment of pediatric tibial fractures in dogs and compare this to other treatment options, where all techniques emphasize biological osteosynthesis. We especially accentuate surgery time, patient comfort level during osteosynthesis, time to clinical union, and complications, including long-term follow-up.
Medical records of five skeletally immature (juvenile) dogs <6 months old with an isolated tibial diaphyseal fracture or a combination of tibial and fibular diaphyseal fractures, treated with MIPEPO aided by fluoroscopy. All dogs experienced excellent levels of comfort and limb functionality and exhibited preserved muscle mass throughout the healing process. The mean duration until plate removal was 27.6 days, with a standard deviation [(SD) ± 9.61; range of 15-36 days] following the operation. Subsequently, four dogs underwent a follow-up examination approximately 1.5 years after plate removal, during which bilateral orthogonal radiographs of the tibia were obtained. These radiographs revealed minimal discrepancies in terms of limb length, frontal plane alignment, and rotational alignment. Furthermore, the owners expressed complete satisfaction with their dogs' recovery and restoration of intended function.
MIPEPO is quick to perform and well tolerated, with rapid fracture healing in juvenile dogs and excellent long-term outcomes. It can be considered along with external fixators and external coaptation when dealing with juvenile diaphyseal fractures.
儿科骨折在狗中相对常见，有多种治疗选择，尤其是对于四肢末端的骨折。无论治疗选择如何，总体目标是快速恢复和出色的长期功能恢复，愈合过程中疼痛和发病率最小。本病例系列旨在报告微创经皮弹性钢板接骨术（MIPEPO）治疗犬胫骨儿科骨折的长期结果，并将其与其他治疗选择进行比较，所有技术均强调生物接骨术。我们特别强调手术时间、接骨过程中患者的舒适度、临床愈合时间和并发症，包括长期随访。
五例骨骼未成熟（幼年）犬的病历记录，年龄均小于 6 个月，患有孤立性胫骨骨干骨折或胫骨和腓骨骨干合并骨折，采用 MIPEPO 治疗，辅以后方射线透视。所有犬在愈合过程中都表现出极佳的舒适度和肢体功能，且保留了肌肉量。平均 27.6 天（标准差 [(SD) ± 9.61；范围 15-36 天]）后去除钢板。随后，4 只犬在去除钢板后大约 1.5 年进行了随访检查，在此期间获得了双侧胫骨正交射线照片。这些射线照片显示，在肢体长度、额状面排列和旋转排列方面差异极小。此外，主人对他们的狗的恢复和预期功能的恢复完全满意。
MIPEPO 操作迅速，耐受性良好，在幼年犬中骨折愈合迅速，长期效果良好。在处理幼年骨干骨折时，可以与外固定器和外固定联合使用。
