摘要

Objective

This study’s purpose was to compare clinical outcomes in adult patients who underwent dual plate versus single plate fixation for humerus fractures to enhance decision-making and patient care.

Methods

Data sources: A pre-registered systematic review and meta-analysis searched four databases on January 9th, 2025. Inclusion criteria were studies that compared dual versus single plate fixation for humerus fractures.

Outcomes included risk of nonunion, risk of total complications, and time until union after surgery. A random effects meta-analysis was done using risk ratio (RR) or unstandardized mean difference.

Results

Thirteen moderate quality retrospective studies were included out of 211 articles retrieved. Patients (n = 788; 47.8% male) had an average age of 50.4 ± 14.2 years and an average follow-up time of 18.1 ± 14.4 months with 378 patients (48.0%) receiving dual plate fixation and 410 patients (52.0%) receiving single plate fixation for humerus fracture (38.4% distal humerus; 61.7% humeral shaft). There was no statistically significant difference in risk of nonunion between dual and single plate fixation groups (p = 0.502; RR: 0.99; 5.0% vs.7.3%). For subgroup analysis by location, there was no statistically significant difference in risk of nonunion for distal humerus fractures or humeral shaft fractures, by surgical indication for risk of nonunion for primary fracture or nonunion, or by surgical indication for time until union for primary fracture or nonunion. There was no statistically significant difference in total complications in all subgroups, except dual plate had an increased risk of total complications versus single plate for distal fractures (p = 0.014; RR: 1.40).

Conclusion

There may be no clinically meaningful differences in risk of nonunion, risk of total complications, and time until union between dual plate versus single plate fixation for humerus fractures in adult patients.
