The investigation into modes of failure of total hip replacements was the purpose of this
project. This involved the development of a finite element model of a simplified uncemented,
simplified cemented and a geometrically real hip in order to study the behaviour
of loosening of the prosthesis.
Loosening of the femoral and acetabular components in total hip replacements are major
long-term complications of hip replacements. Such loosening usually produces substantial
loss of supporting bone making revision much more difficult and less successful than
primary surgery.
Implant loosening can be caused from resorption of the bone around the prosthesis from
wear debris, insufficient osseointegration of the bone into the prosthesis and brittle failure
of the bone cement.
