Background: The aim of the study was to report the 2-year outcome after a displaced 4-part fracture of the proximal humerus in elderly patients randomized to treatment with a hemiarthroplasty (HA) or nonoperative treatment.
Patients and Methods: We included 55 patients, mean age 77 (range, 58-92) years, 86% being women. Follow-up examinations were done at 4, 12, and 24 months. The main outcome measures were health-related quality of life (HRQoL) according to the EQ-5D and the DASH and Constant scores.
Results: At the final 2-year follow-up the HRQoL was significantly better in the HA group compared to the nonoperative group, EQ-5D(index) score 0.81 compared to 0.65 (P=.02). The results for DASH and pain assessment were both in favor of the HA group, DASH score 30 versus 37 (P=.25) and pain according to VAS 15 versus 25 (P=.17). There were no significant differences regarding the Constant score or range of motion (ROM). Both groups achieved a mean flexion of approximately 90-95 degrees and a mean abduction of 85-90 degrees. The need for additional surgery was low: 3 patients in the HA group and 1 patient in the nonoperative group.
Conclusion: The results of the study demonstrated a significant advantage in quality of life in favor of HA, as compared to nonoperative treatment in elderly patients with a displaced 4-part fracture of the proximal humerus. The main advantage of HA appeared to be less pain while there were no differences in ROM.
Level of evidence: Level I, Randomized Controlled Trial, Treatment Study.
