Abstract
The stem for joint prostheses, in particular for hip prosthesis, has a proximal neck region (1), a lateral tension region (2), a medial compression region (3) and a central region (4) lying between said lateral and medial regions (2,3). The central region (4) is provided with a regular pattern of anteroposterior cuts (5) extending from said proximal region (1) to the distal end (6) of the stem rendering the stem stiffness adaptable to the stiffness of the receiving bone cavity.
