Buttressing the intermediate and radial columns

In dorsal double plating, the intermediate column and the radial column are buttressed, each with a separate plate. The radial column is buttressed by a plate placed radially, deep to the first extensor compartment. The intermediate column is buttressed with a separate, precontoured plate on the dorsal aspect of the intermediate column.

A buttress plate resists axial load by applying a force at 90° to the axis of potential displacement.
