Trials (169 001ND, 169 002ND, 169 003ND,
169 004ND) are used to determine the appropriate
implant size.
The trial should be positioned laterally,
in order to provide:
2 to 3 holes in the short J-shaped or
L-shaped part of the plate facing the calcaneus
The oblong central hole facing the talus,
if any is present
The long part of the plate aligned with
the tibia
K-wires (reference 115 216ND) are used
for temporary fixation of the trial, and
implant
(figure 2)
The trials are flexible and allow contouring
to the lateral surface of the calcaneus,
the talus and the tibia
The contoured trial may be used as a template
for contouring the final implant later in
the procedure
Plate Contouring
The plates are pre-bent to better fit
the lateral aspect of the hindfoot. However,
when deemed necessary by the surgeon, the
plate may be further contoured using plate
benders (129 765ND) as shown in figures
3a and 3b.
Warning: It is
imperative that the bending be implemented
between two consecutive lipped holes. If
not, the intermediate threaded holes may
be damaged or deformed and the locking function
minimized or lost.
Implant Positioning
The implant is selected, based on the
size defined using the trial plate
The plate can slide along the k-wire(s)
used to position the trial plate (figure
4)
The k-wires serve as temporary fixation
during preparation of the screw holes
