Objective: explore the clinical efficacy of multi-dimensional intramedullary nail in the treatment of middle-aged and elderly patients with proximal humeral fracture. Methods: A total of 60 middle-aged and elderly patients diagnosed with proximal humeral fractures were selected from May 2020 to May 2022. The patients were divided into 2 groups according to the average, and different treatment methods were implemented. To explore and analyze the clinical effect of multi-dimensional intramedullary nail treatment in the study group compared with open reduction and plate internal fixation. Results: (1) In terms of surgical indexes, except healing time and hospital stay, the other indexes of multi-dimensional intramedullary nail treatment were more excellent, and the difference was significant (p < 0.05); (2) In terms of Constant score, there was no significant difference between the two groups before treatment (p > 0.05), but the score of the study group was more excellent after treatment, and the difference was significant (p < 0.05). (3) In terms of shoulder joint ROM, there were no significant differences in other related indexes between the two groups except δcervical shaft Angle (p > 0.05). Conclusion: Multi-dimensional intramedullary nailing can achieve better outcomes in middle-aged and elderly patients with confirmed proximal humeral fractures.
