7Definitive screw fixation

Subchondral fixation

In some cases provisional K-wire stabilization is not possible.

When there is no intact posterior distal humerus onto which to fix the fragment, or when the fragment is too small to accept a screw, small threaded K-wires, or absorbable pins can be used.

These fragments are stabilized to an adjacent fragment by drilling small threaded K-wires from one fragment to the next in the subchondral bone.
