Antibiotic-loaded cement spacers are used in two- stage hip replacement. The aim of our study was to compare our results using a Spacer-G with previous results reported in the literature. From June 2002 to April 2010, all patients treated with a two-stage revision were retrospectively reviewed. On the basis of the results of the first-stage procedure, 52 patients underwent the second stage, six developed a dislocation, in eight the spacer was maintained, and five patients developed an acute infection of the spacer or the infection was not resolved. With regard to the second-stage procedure the revision was successful in 44 patients, a re-infection developed in four patients and the definitive prosthesis presented a mechanical complication in four more. The literature results reported that 97.5% of the spacers were reimplanted, although 12.09% of them developed a dislocation. Surgeons must assess several aspects so as to avoid mechanical complications like dislocation and re- infections during the two stages of the procedure.
