Final Reduction
If desired, another trial reduction can be accomplished
prior to selecting final head size and impacting the
modular head onto the stem (Figure 20). Provisional
heads in seven neck lengths allow an additional trial
reduction using the actual implant to ensure proper
leg length and stability. After fully seating the femoral
component, impact the appropriate modular head
onto the clean, dry taper.
Inserting the Locking Screw
To lock the distal and proximal body implants, thread
the locking screw into the top of the proximal body
using the 3.5 mm hex driver and the T-handle in
torque limiting position until a “click” is felt and heard
(Figure 19).
Note:
The screw can be used to lock the proximal
body and distal stem together before the implants
are inserted into the femur. If this is done, check
the security of the screw once the implant has been
fully seated.
