Abstract

This study aimed to evaluate the outcomes of open reduction and internal fixation with a locking compression plate in the treatment of closed humeral shaft fractures at Thanh Hoa Provincial General Hospital. A retrospective-prospective descriptive study was conducted in 48 patients with closed humeral shaft fractures who underwent surgery between January 2023 and September 2024. The mean age was 38.8 ± 14.3 years, and the male-to-female ratio was 32:16. Road traffic accidents were the leading cause of injury, accounting for 54.2% of cases. Fractures of the middle third of the humeral shaft were the most common, accounting for 62.5%. According to the AO classification, type A fractures accounted for 75.0%, type B for 22.9%, and type C for 2.1%. All patients achieved primary wound healing, and no surgical site infection was recorded. Postoperative radial nerve palsy occurred in 6.3% of cases and recovered completely within 6 months. Fracture union was achieved in 95.8% of cases; delayed union and nonunion each accounted for 2.1%. According to the modified Neer criteria, excellent and good results were obtained in 93.8% of patients, fair results in 4.2%, and poor results in 2.1%. ORIF with a locking compression plate is an effective method for treating closed humeral shaft fractures, with a high union rate, a low complication rate, and favorable functional outcomes.
