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. Additional References about Total Hips Replacements:
