The philosophy of anatomical stems was introduced into the market during the 1980’s with the aim to obtain the best press-fit in the metaphyseal femur using a design following the natural geometry of the proximal femur. The MiniMAX^® is an anatomical cementless stem engineered to provide the best fit and fill in the metaphyseal femur following the natural shape of the femoral canal. ^[1,2] The length of the stem and the shape have been studied size by size and have shown to be bone preserving and to provide good mechanical stability.^[3]
