Revision Hip Surgery
This surgery replaces worn THR - total hip parts and damaged
bone. New, specially made metal, plastic or ceramic
components are used to restore normal hip joint stability.
Step 1The old plastic liner and metal socket
components are removed.
Step 2
Morselized bone (bone in particle form) is
used to strengthen the socket and fill bone
cavities. Allograft (segments of bone) also may
be used for support. It also may be necessary to
use a wire mesh to hold the socket's shape.
Step 3
The new metal socket is pressed into place.
Step 4
A new plastic, metal or ceramic shell liner
is pressed into place.
Step 5
To remove the old femoral component, the
bone around it may be cut into sections (called
an osteotomy).
Step 6
After the bone segments are cleaned of old
cement. The new metal femoral component is
pressed or cemented into place.
Step 7
Wire is used to close the bone segments
tightly around the component. The wires may also
hold struts of bone graft in place to strengthen
the femur.
Step 8
A new metal or ceramic ball is placed on the
femoral component.
