For a correct placement and early fixation of an uncemented hip prosthesis, a centralizer is used. Normally, the centralizer is made of PMMA, the same material as bone cement. When a revision is needed, PMMA is difficult to remove, which is one of the reason not to use a cemented hip prosthesis. With a PMMA centralizer, still PMMA will remain in the bone and needs to be removed in case of a revision. PEGT/PBT is a reabsorbable material, which gives stability during the first month after the placement of the hip prosthesis. However, PEGT/PBT is reabsorped afterwards and, therefore, will not interfere with a revision procedure.
