    Hi-Fidelity Concept

    By utilizing a four-strut compression system

    which effectively loads the soft tissue surroundingthe residual bony segment, and with the

    incorporation of associated tissue relief, one canachieve maximal long bone stabilization outside

    of the confines of basic hydrostatic limitations.

    Hi-Fi Humeral App. By compressing the soft

    tissue between the humeral

    long bone and the

    associated biceps/triceps

    mm bellies, and allowingsoft tissue to flow

    anteriorly, posteriorly,

    medially, and laterally

    without restriction, a

    greater depth ofcompression is achieved

    along the shaft of the

    residual bony segment.
