SHINE-C ® shaft has been designed after an anthropometric study conducted by an eminent group of experts in surgery COT. His goal was to combine in a stem those morphological characteristics that could provide a more stable against rotational stresses that can derail the implant loosening behavior. Stem SHINE-C ® is intelligently designed: at its proximal or metaphyseal area, has a progressive trapezoidal geometry is further enhanced by a warped surface allows optimum anti-rotational response. Stem SHINE-C ® is a cemented prosthesis.
