Fully
porous-coated cementless stem has the advantage of good initial metaphyseal to
diaphysial fixation. However, it is very difficult to remove the stem when
complications develop.
Extraction of a
stem may cause huge damage to the femur. A long stem may be required to ensure
stability for subsequent femoral reconstruction. Here
we present a case employing a novel technique of minimizing invasion to the
femur when a wellfixed, extensively porous-coated cementless stem needs to be
removed.
A 58-year-old
woman had a revision total hip arthroplasty for trunnionosis after the left
total hip arthroplasty. In the operation we made two cortical windows to the
femur. It enabled us to reach all circumferences of the stem. By this technique
the stem could be easily removed and the femoral canal structure was preserved.
The femur could then be reconstructed with a stem of normal length.
