Monteggia fractures (MFs) are proximal ulnar fractures with concurrent dislocation of the radial head. This retrospective study aims to report the clinical findings and discuss the treatments and outcomes in MFs cases of 9 cases. Previous medical records of the animals were reviewed for history, clinical features, radiographic findings and choice of treatment. Treatment follow-up was evaluated over the telephone by discussion with the owners. Six animals included in the study were presented 2 days after the initial trauma. Five dogs were presented after common road traffic accidents and two after unknown traumas. All dogs had type I MFs, while the cat had a type III MF. Radiographical findings showed that six animals had extra-articular ulnar fractures, while three animals had intra-articular ulnar fractures. All animals were treated with open reduction of the ulna and internal fixation surgical methods. Six ulnar fractures were stabilized with intramedullary pin(s) with cerclage wire. The clinical outcome was assessed by the owners as full function in 3 dogs, acceptable function in 2 dogs and unacceptable function in 2 dogs with intraarticular ulnar fractures. The cat case was rated as full function. One dog died from a pulmonary fat embolism. The findings presented here provide some support that cerclage wire placement could be a satisfactory method for annular ligament reconstruction as a simple and economical treatment option. Also, to the authors' knowledge, this is the third report of MFs with intraarticular ulnar fractures. In this series, comminuted, intraarticular fractures were related to major postoperative complications.
孟氏骨折（Monteggia fractures，MFs）是指伴有桡骨头脱位的尺骨近端骨折。本回顾性研究旨在报告 9 例 MFs 病例的临床发现，并讨论其治疗方法和结果。回顾了动物的既往病历，包括病史、临床特征、影像学发现和治疗选择。通过与主人讨论电话随访治疗结果。研究纳入的 6 只动物在初次创伤后 2 天就诊。5 只狗因常见的道路交通意外就诊，2 只因未知创伤就诊。所有狗均为 I 型 MFs，而猫为 III 型 MFs。影像学发现 6 只动物有骺外尺骨骨折，3 只动物有骺内尺骨骨折。所有动物均采用切开复位和内固定手术方法治疗。6 例尺骨骨折采用髓内钉（带环形钢丝）固定。通过主人评估临床结果，3 只狗功能完全恢复，2 只狗功能可接受，2 只狗有骺内尺骨骨折，功能不可接受。猫病例被评为功能完全恢复。1 只狗死于肺脂肪栓塞。本研究结果为环形钢丝固定可作为环状韧带重建的一种简单、经济的治疗选择提供了一定的支持。此外，据作者所知，这是第三例骺内尺骨骨折的 MFs 报告。在本系列中，粉碎性、骺内骨折与主要术后并发症有关。
