Comparison of cemented and uncemented hemiarthroplasty results in the treatment of comminuted displaced proximal humeral fractures

Abstract

Aim: In this study, we aimed to compare the results of cemented and uncemented hemiarthroplasty results in elderly patients for the treatment of comminuted proximal humerus fractures. Material and Method: Between 2008 and 2014, patients who underwent hemiarthroplasty due to comminuted proximal humerus fracture were retrospectively investigated using the data system of two university hospitals. Patients who were followed for at least 2 years were included. Demographic information of the patients, fracture type, functional results at final follow-up, visual analog scale score and satisfaction status, radiological results, mean follow-up time and complications were noted. Results: A total of 22 patients (12 males, 10 females) (mean age: 76.4 years, range: 67-88)(8 cemented hemiarthroplasty, 14 uncemented hemiarthroplasty) were included. The mean follow-up time was 38 months. Although the mean forward elevation, external rotation and internal rotation were better in patients who underwent uncemented hemiarthroplasty, no significant difference was found between the two groups. The mean visual analog scale score in uncemented hemiarthroplasty group was 0.87 ± 1.12, whereas the mean visual analog scale score in cemented group was 1.28 ± 0.91 and no significant difference was found (p = 0.33). At radiologic evaluation, no significant difference was found. Periprosthetic fracture was seen in 1 patient of both groups. We have seen 1 shoulder stiffness in uncemented group and 1 deep tissue infection in cemented hemiarthroplasty group. Conclusion: The functional and radiological results of our cemented and uncemented HA patients were similar for the treatment of comminuted proximal humerus fractures in at least 2 years follow-up.
