Comparison between primary total elbow arthroplasty versus open reduction and internal fixation in elderly patients with distal humerus fractures: a prospective study

Abstract

Objective: It aims to assess the efficacy of these treatments, specifically in the presence of osteoporotic bone conditions. The findings of this study offer insights into the suitability of TEA as an alternative treatment option in such cases. Methods: In this study, sixty patients with distal humerus fractures were divided into two groups. The first group received ORIF for fracture fixation, while the second group underwent primary TEA treatment. The study evaluated various outcomes, including elbow range of movement, elbow stability, and comparison of Mayo Elbow Performance Scores (MEPS) between the two groups at three- and twelve-month follow-up periods. Results: In the three- and twelve-month follow-up periods, noticeable differences in elbow motion range were observed between the ORIF and TEA groups. The ORIF group experienced more significant restrictions in daily activities due to stiffness and pain, unlike the TEA group. However, both groups showed improvements in elbow function after one year. Furthermore, there were significant differences in the mean MEPS between the two groups at the three- and twelve-month follow-up period. However, no considerable differences were found between these periods within either group. Conclusion: TEA is emerging as a promising option for elderly patients with comminuted distal humerus fractures, considering the osteoporotic bone condition. The results of this study hold substantial implications for the decision-making process in treatment selection.
