In fractures with markedly displaced proximal, metaphyseal fragmentation it is crucial to still achieve anatomic or almost anatomic reduction. The older the patient, the more important this is, to prevent nonunion and regain optimal function.

To achieve this, the plate should provide sufficient fixation points in the proximal humerus/humeral head. It also should be long enough. Typically, 6 cortical fixation points distal to the fracture zone are sufficient.

Bridge plating alone does not address grossly displaced fragments. In the elderly patient this may lead to delayed or nonunion. Therefore, consider adding techniques such as cerclage or lag screw fixation of large fragments, or choose a different treatment.
