Results of Plate Osteosynthesis with Deltopectoral Approach for Proximal Humerus Fractures.

Aim: The aim of this study is to evaluate the functional and radiological results of patients who underwent plate osteosynthesis with the deltopectoral approach in proximal humerus fractures, according to the intact shoulder. Materials and Methods: Our study included 33 patients who underwent proximal humeral anatomic locking plate with deltopectoral approach due to proximal humeral fracture (PHF) between 2015 and 2017. Patients over 18 years of age, with closed humeral fractures, and with intact contralateral humerus and shoulder were included in our retrospective study. The functional results between the operated and healthy sides of the patients were evaluated by comparing the Constant-Murley score and radiological results with the full anteroposterior radiography and the collodiaphyseal angles. Results: According to the Constant Murley scoring categorical data structure of the patients, the operated side was 6.1% (n=2) poor, 6.1% (n=2) moderate, 39.4% (n=13) good, 48.5% (n=16) excellent, while the healthy side was %. The results were 0% (n=0) poor, 3% (n=1) moderate, 30.3% (n=10) good, and 66.7% (n:22) excellent. According to the Constant Murley scoring categorical data structure, a statistical difference was found between the operated side and the healthy side (p>0.05). While the mean Constant Murley score of the operated side was 85.82 ± 7.07, the mean Constant Murley score of the healthy side was 90.67 ± 5.76. While the average of the collodiaphyseal angles of the operated side was 130.03± 4.64; the mean of the angles of the intact side was 135.64 ± 5.04. In terms of Constant Murley shoulder scores and collodiaphyseal angle values of the patients; a statistical difference was observed between the operated sides and the healthy sides (p<0.05). Conclusion: It has been observed that both clinical and functional results of the patients were successful after plate osteosynthesis using the deltopectoral approach and proximal humerus anatomical locking plate in proximal humerus fractures.
