Comparison of minimally invasive plate osteosynthesis (MIPO) and open reduction and internal fixation (ORIF) for the treatment of radial shaft fractures: a retrospective study.

BACKGROUND

Minimally Invasive Plate Osteosynthesis (MIPO) has emerged as an option for the treatment of fractures; however, there is limited literature regarding its application in radius shaft fractures. The purpose of this study was to introduce a MIPO technique for treating radius shaft fractures and to compare its clinical and radiologic outcomes with those of open reduction and internal fixation using a plate (ORIF).

METHODS

A retrospective analysis was conducted on 49 cases of diaphyseal radius fractures between March 2018 and November 2021. The MIPO group (20 patients) and ORIF group (29 patients) were treated by a single surgeon. Clinical outcomes were evaluated based on union rates, range of motion (ROM), and complications. Radiological assessments included fracture healing, ulnar variance, and alignment.

RESULTS

Union was achieved in all cases in both groups. The union time was similar, with 13.1 weeks for the MIPO group and 12.6 weeks for the ORIF group. Forearm rotation was comparable between the two groups (MIPO: supination 87.3°, pronation 79.5°; ORIF: supination 87.4°, pronation 80.2°). Clinical outcomes were excellent in 92.3% of MIPO patients and 96.5% of ORIF patients. Ulnar variance was similar in both groups, indicating good alignment and preservation of length. No complications, such as infection or neurovascular injury, were observed in either group.

CONCLUSION

In our study, the MIPO technique for radius shaft fractures demonstrated clinically favorable outcomes without major complications. However, further research with larger sample sizes and longer follow-up periods is needed to fully evaluate the utility and long-term outcomes of the MIPO technique for radius shaft fractures.
