Introduction: Minimally invasive plate osteosynthesis (MIPO) is an effective treatment modality for fracture fixation. The only published data regarding MIPO for humeral fracture stabilization in companion animals describes a medial humeral approach. This case series describes the Results of cases undergoing humeral fracture stabilization utilizing MIPO via a lateral humeral approach.

Materials and Methods: Medical records, pre- and post-operative radiographs of the fractured humeri, radiographs of the contralateral humeri, and operative reports for dogs and cats that underwent humeral fracture stabilization using MIPO via a lateral humeral approach were analysed. Surgical technique and implant selection were recorded. Humeral joint angles, mechanical axes, and length of post-operative and contralateral humeri were directly compared with objectively determine post-operative frontal and sagittal plane alignment, and post-operative humeral length change. When available, time to osseus union and post-operative complications were recorded.

Results: Fractures sustained by seven dogs and four cats were included. All fractures were stabilized with an intramedullary rod, a lateral bone plate and screws. The mean ± SD absolute differences in frontal and sagittal plane alignment between the contralateral and post-operative humeri were 1.93 ± 1.26 degrees and 4.28 ± 1.53 degrees, respectively. The mean absolute difference ± SD in humeral length change was 2.73% ± 3.9%. Mean ± SD time to osseus union in available cases was 103 ± 49 days. Post-operative complications occurred in five cases.

Discussion/Conclusion: MIPO stabilization performed via a lateral humeral approach appears to be an acceptable means of stabilizing diaphyseal humeral fractures in both dogs and cats.
