Research experimental of hipbone arthroplasties using tensometric models

Hip prostheses functionality is limited in time, inter alia, bymechanical damage to the femoral components (protrusion, limestoneresorption femoral loosening), and by of accurate positioning of the piecefemoral. To assess the importance of accurate positioning of the piecefemoral hip arthroplasties we performed a tensometric study onexperimental models on femurs dehydrated and lubricated, the prostheseswere implanted cemented in varum, normal and valgus position. Thespecific model distortions were determined by applying tensometric stanceon the external and internal cortical in maximal stress positions and requestusing static strength values similar to those that require bone during normalgait. Aim of this experiment is to determine the maximum load areasfemur which has been implanted partial prostheses.
