Several modalities of treatment are currently available for
the management of diaphyseal humeral fractures. A long arm cast,
a functional brace, an external fixator, a compression plate, and
an intramedullary rod are different devices used to achieve the
same ultimate results, but the biological mechanisms through which
they accomplish this vary. Each one of these devices has a place
in the management of humeral shaft fractures, and no one treatment
is superior under all circumstances.
