Evaluation of results of Minimally Invasive Plate Osteosynthesis (MIPO) with long PHILOS plate for complex metadiaphyseal proximal humerus fractures in elderly

Background: Proximal humerus fractures are common in elderly people. The purpose of the study is to evaluate the results of Minimally Invasive Plate Osteosyhthesis (MIPO) plating with Long PHIL

Methods: A prospective observation study conducted between 1^st January 2017 to 30^th December 2019. Total 10 elderly patients between 62 to 81 years of age with metadiaphyseal proximal humerus fractures were included. Radiological assessment was done at 6 weeks, 3 months, 6 months and at 1 year follow up. Functional evaluation was done with DASH score and Constant- Murley score at 1 year follow up.

Results: 100% union rate was observed. No case of non-union, malunion, infection, nerve injury and implant breakage was reported. 1 case had shoulder impingement at final follow up. The average DASH score was 23.7 and average Constant-Murley score was 82.6 at 1 year follow up.

Conclusion: MIPO is a safe and effective method for complex metadiaphyseal proximal humerus fractures in the elderly.
