[Two-stage procedure to exchange XXXX . Early results after implantation of a reverse modular hybrid endoprosthesis].

@entity691 @entity1 @entity281
BACKGROUND: Between January 2001 and January 2005 we performed the exchange of infected total hip arthroplasties in 40 cases. MATERIAL AND METHODS: We applied a two-stage procedure when implant salvage was not possible. Our treatment algorithm included complete removal of the infected material, thorough d  bridement, and repeated revisions until cultures were negative. We then implanted a cemented acetabular @entity691 cup with specific antibiotic addition and a cementless modular stem (reverse modular hybrid endoprosthesis). Appropriate intravenous and oral antibiotic therapy was prescribed. RESULTS: A total of 18 @entity1 and 22 @entity1 (age 48-86 years) were followed up for 4-48 months (mean: 12 months). Up to now 38 have remained @entity281 free; in two cases the treatment failed and a resection arthroplasty had to be performed. There were eight complications intraoperatively (shaft fractures); four of them were treated conservatively and four needed additional stabilization. The mean hip score improved from 21 points initially to 81 points at the last examination. All details are listed in table form. Two-stage revision hip arthroplasty for @entity281 using the inverse modular hybrid technique seems to be a safe and reliable method. Further investigation and a larger number of @entity1 are necessary to confirm these preliminary results.
