Abstract
In case of stem loosening in periprosthetic femoral fractures PPFF revision arthroplasty should be performed The first hypothesis of this study was that advanced patient age and female gender shows higher nonunion rates The second hypothesis was that primary cementless arthroplasty is associated with a higher nonunion rate compared to cemented primary hip arthroplastyEighty one patients 78 female met the inclusion criteria In 20/81 patients 247 no adequate fracture healing could be determined on radiographs 12 months after revision surgery Although age and female gender showed a positive correlation with bony nonunion after PPFF as expected the pvalues were not statistically significant Multiple regression analysis revealed primary cementless prosthesis p = 0001 to be the only independent variable associated with nonunionNoncemented primary prosthesis might be a negative predicting factor for the development of nonunion after longstem revision arthroplasty in PPFF We therefore recommend the thorough debridement of pannus tissue thus inducing bone healing before the implantation of revision prostheses
