Background: Shaft fractures account for 20% and 1-3% of all humerus fractures, respectively. Open dynamic compression plate fixation (Open fixation with DCP) with absolute stability is the current gold standard for treating shaft humerus fractures. The goal of MIPO was to provide a more stable fixation, which would increase the union rate and decrease open plating side effects including infection and radial nerve palsy.

Aim: The purpose of this study was to assess the clinical and radiological outcomes of the MIPPO technique in the treatment of humeral shaft fractures.

Patients and methods: thirty cases of shaft humerus fractures were examined during the period from August 2022 to March 2023. The history, clinical examination, and radiographic (X-ray) examination were used to select cases. According to UCLA score, the result was noted and filled up.

Results: Union was achieved in 17 to 22 weeks with the mean 19.4±4.1. Only 5% nonunion was seen in our cases. It was observed that the median UCLA score was excellent (34).

Conclusion: In shaft humerus fractures, results from minimally invasive plate osteosynthesis with anterior bridge plating were favorable. They offer the fracture site some support, and the fracture hematoma is not disturbed. MIPO keeps the blood vessels healthy, which lowers the danger of infection and wound disintegration.
