Abstract

A femoral stem (1) of an endoprosthesis of the mini-invasive type of a coxofemoral joint, comprising a distal portion (2), which is substantially longitudinally elongated and is suitable to be inserted in the bone cavity of a femur, the femoral stem comprising a proximal portion (13), which is suitable to be accommodated proximate to the trochanteric region of the femur and extends into a neck (4) provided with a shank (5) for coupling to a spherical head of the coxofemoral joint, the femoral stem, viewed on a frontal plane, having an inner side and an outer side, the outer side having a convex profile that comprises at least one first straight segment (20) that delimits the distal portion (2) and a second straight segment (30) that delimits the proximal portion (3), the second straight segment (30) being inclined with respect to the longitudinal axis of the distal portion (2) toward the coxofemoral joint at an acute trochanteric angle (β).
