Trial body assemblies have been designed
so that when the teeth on the underside
of the trial body mate with the teeth on the
proximal spacer when initially placed. When the
components are properly mated the screw on
the top of the trial body pops up. See Figure 10.
Secure the trial components together by
tightening the screw of the trial body with the
trial assembly instrument. Advance the trial
body screw until it is flush with the top of the
trial body. Figure 11 and 12.
Once the trial body assembly is tightly secured,
place the desired trial neck (Standard or High
offset) on the trial body. Attach the selected trial
head to the trial neck. Perform trial reduction
and range of motion (ROM) exercise to confirm
proper seating of implant, assess joint tension
and there is no impingement to the hip. Adjust
trial components and position of trial neck to
achieve desired neck offset and neck version.
(see figure 13) For version adjustment, loosen
trial body screw and rotate trial body to desired
position. Use a cautery pen to mark desired
position of the implant. Retighten screw and
perform trial reduction again to confirm position.
