Comparison of Conservative and Arthroplasty Treatment for 3- or 4-Part Proximal Humerus Fractures in the Elderly

Aim: Proximal humerus fractures are common injuries in the elderly population. This study hypothesizes that arthroplasty is not superior to conservative treatment in the management of multi-part proximal humerus fractures in elderly patients. Material and Method: Patients aged 65 and above with 3–4-part proximal humerus fractures, treated either conservatively or with arthroplasty, were included in the study. The minimum follow-up period was set at 12 months. Functional evaluations of the patients were performed using the Quick Disabilities of Arm, Shoulder and Hand (Q-DASH) scoring system. Statistical analysis comparing the two groups was conducted using the SPSS software. The mean values of numerical data were analyzed using the Mann-Whitney U test, while categorical data were compared using the Chi-square test. A significant level of 0.05 was considered. Results: A total of 67 patients who received adequate clinical follow-up were included in the study (50 conservative 17 arthroplasty). The average age of the patients was 76.12 years, with 9 male and 58 female patients. The average follow-up period was 22.61 months (range: 12-82). There were no statistically significant differences in age, gender, side, follow-up period, and fracture type distribution between the two groups. However, a significant difference in Q-DASH scores was observed (p
