Phemoral stem for hip prothesis and instrument for medullary canal preparation

Abstract

Abstract The assembly comprises a metaphysial element (1) and a diaphysial element (2) in two separate and independent parts, each element (1) and (2) having a specific anteroposterior sagittal curvature, in order to correspond with the anatomical double curvature of the femur and have coupling arrangements which are suited, on the one hand, to solidly attaching them with a capacity for free rotation at the moment of introduction into the medullary canal for their auto-adaptation and, on the other hand, to solidly attach them while creating an effect of compressing the metaphysial element (1) with respect to the diaphysial element (2) after introduction into the medullary canal. <IMAGE>
