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.
