Spindle
(cont.)
Measure the cortical thickness along the perimeter
of the resection level using a ruler, calipers or the
cortical gauge of the spindle sizer (Figure 55). Based
on the measurement, reference the Compress Device
Force Table to select the appropriate force level that
corresponds to the measured thickness.
Note:
If using the cortical gauge of the spindle
sizer, place the gauge onto the thinnest portion of
the cortical wall to determine the appropriate force
level (400 lb/600 lb/800 lb) (Figure 56).

Not Indicated*
2.5–3.9
400
4.0–5.4

*Cortical thickness less than 2.5 mm is a contraindication for this system.
Note:
Cortical thickness should not exceed range
anywhere between the anchor plug and the
interface.
Note:
Any cortical defect between the anchor plug
and interface is a contraindication for this system.
