frequency and force to minimize temperature elevation and
thermal necrosis as claimed.
There is further no descriptive support for the recitation
in independent claim 24 that the "fixation wire" (which as
broadly recited includes all such wires) requires
"comparatively more force" for removal from the bone than would
be required for such a wire that was inserted by rotation.
Fig. 8 of the drawing is directed to a bar chart that provides
a comparative showing of the mean peak pull out force for each
of three wires of different diameter. This comparative 4
showing reveals that the mean peak pull out force for the
Kirscher wires installed by a rotary drill are in some cases
4According to pages 10-12 of the specification three
different-sized trocar-tipped Kirscher or K-wires (0.028,
0.045 and 0.062 inches in diameter) were evaluated for
drilling force and pull-out force on the tibias of two
rabbits. With respect to this evaluation the specification
states that:
Five new K-wires for each size were tested on
three tibias using either the rotary or oscillating
drill. Each tibia had ten drilled holes, 4mm apart,
equally spaced along the mid-diaphysis. The SAS t-
test was used to evaluate the differences in mean
peak axial loads and mean peak pull-out forces for
thirty point configurations for the two drills.
