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 tools. An osteotomy of the femur may

be necessary to facilitate removal of the cement.

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).
