A common situation presenting to the orthopaedic
surgeon today is a worn acetabular liner with substantial acetabular
and pelvic osteolysis. The surgeon has many options for dealing
with osteolytic defects. These include allograft, calcium based
substitutes, demineralised bone matrix, or combinations of these
options with or without addition of platelet rich plasma. To date
there are no clinical studies to determine the efficacy of using
bone-stimulating materials in osteolytic defects at the time of
revision surgery and there are surprisingly few studies demonstrating
the clinical efficacy of these treatment options. Even when radiographs
appear to demonstrate incorporation of graft material CT studies
have shown that incorporation is incomplete. The surgeon, in choosing
a graft material for a surgical procedure must take into account
the efficacy, safety, cost and convenience of that material. Cite this article:
