A retrospective study was conducted to evaluate the results of two-stage surgical treatment for infected hip implant using two different spacers in antibiotic-impregnated cement, one custom-made and one pre-formed. Out of a total of 20 patients treated between 1995 and 2003, the temporary implant of one custom-made spacer was carried out in 8 cases, while in the remaining 12 cases we resorted to using a pre-formed spacer (Spacer G). In both groups we observed one recurrence of infection, for an overall 90% success rate in terms of eradication of the infection. Custom-made spacers had a greater incidence of local complications (1 breakage, 1 dislocation, 1 sinking of the revision stem) as compared to pre-formed ones (1 dislocation). The clinical results evaluated using the Harris Hip Score showed a statistically significant difference (p < 0.05) in both groups as compared to the preoperative score. The use of a pre-formed spacer, although more costly as compared to that custom-made one, was advantageous in some ways, for example in terms of standardization of the implant method, the lower incidence of mechanical complications and the better functional results.

Abstract
A retrospective study was conducted to evaluate the results of two-stage surgical treatment for infected hip implant using two different spacers in antibiotic-impregnated cement, one custom-made and one pre-formed. Out of a total of 20 patients treated between 1995 and 2003, the temporary implant of one custom-made spacer was carried out in 8 cases, while in the remaining 12 cases we resorted to using a pre-formed spacer (Spacer G). In both groups we observed one recurrence of infection, for an overall 90% success rate in terms of eradication of the infection. Custom-made spacers had a greater incidence of local complications (1 breakage, 1 dislocation, 1 sinking of the revision stem) as compared to pre-formed ones (1 dislocation). The clinical results evaluated using the Harris Hip Score showed a statistically significant difference (p < 0.05) in both groups as compared to the preoperative score. The use of a pre-formed spacer, although more costly as compared to that custom-made one, was advantageous in some ways, for example in terms of standardization of the implant method, the lower incidence of mechanical complications and the better functional results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
