Inserting The Locking Screw - Zimmer Biomet Arcos Modular Femoral Revision System Surgical Technique

Figure 67 Figure 68
Disengage the proximal/distal inserter by pulling
back on the inserter collar (Figure 67). To remove the
proximal fastener, utilize the taper assembly driver
and unthread the proximal fastener from the proximal
body implant (Figure 68).
Note: This inserter disassembly technique will NOT
disassemble the implant.
Note: To confirm that the proximal body is fully
seated onto the taper junction an optional taper
engagement tool is available. Insert the taper
engagement tool into the top of the proximal body.
Verify that the etch mark depth (50, 60, 70 or 80)
on the engagement tool aligns with the lateral
shoulder of the proximal body implant chosen
(Figure 69). The taper engagement tool may only
be used prior to inserting the locking screw.

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 T-handle in torque
limiting position until a "click" is felt and heard
(Figure 70).
Note: If the screw does not thread into the distal
stem the proximal body is not fully seated and the
final implant assembly steps must be repeated.
