Locking plate for displaced proximal humerus fractures-outcomes and complications: a prospective study

Background: The management of unstable proximal humerus fractures is controversial as many fixation techniques have evolved over the years claiming to be a better fixation device compared to the other.Methods: 23 patients with closed displaced proximal humerus fractures were included in this study. All patients underwent open reduction and internal fixation with proximal humerus locking plate through either delto-pectoral or deltoid splitting approach. Standard shoulder rehabilitation program was used in all cases. Functional and radiological outcome were assessed at follow-up.Results: The mean constant-Murley score achieved at 6 months was 66. Complications were reported in a total of 7 patients including 3 varus malunion, 1 valgus malunion, 2 screw penetration into the joint and 1 nonunion with implant breakage.Conclusions: The proximal humeral locking plate seems to be an adequate device for the fixation of displaced proximal humerus fractures as 83% of our study population had good/moderate functional outcomes.
