Removal of a Cementless Stem
Removal of a cementless stem may be difficult due to
the biologic fixation that may exist between the implant
and bone. When removing a proximally porous coated
stem, it may be necessary to perform an osteotomy
of the femur just below the level of the porous coating
to assist in stem removal (Figure 4).
Note: An extended trochanteric osteotomy may be
necessary if removing an extensively coated stem.
Sectioning the stem and utilizing trephine reamers
can assist in the removal of the porous coated distal
segment of a cementless stem (Figure 5).
Removal of a Cemented Component
Once the stem has been removed from the cement
mantle by utilizing universal extraction instruments or
manufacturer specific instruments, ensure all cement is
removed prior to preparation of the femur for the Arcos
femoral components (Figure 3). This can be achieved
using the Ultra-Drive
® cement removal system or
cement removal tools. An osteotomy of the femur may
be necessary to facilitate removal of the cement.
