Abstract
The shank is provided with a recess in the proximal medial region and a U-shaped wire mesh structure is secured within the recess. The wire mesh structure provides for an ingrowth of bone tissue at the medial narrow side of the shank and an absorption of shear micro movements between a bone and the implant. The mesh structure can be secured in place by rivets or by weld seams.
