Abstract
Bony ingrowth of short stems is under investigation. Over one year bony reactions around the Metha<sup>®</sup> stem were investigated using the DXA method in a standardized zonal system (19 ROIs). Clinical results were documented using the HHS. HHS significantly improved from 46 points to 97 points. After one year bone marrow density (BMD) increased in the lateral distal and lateral proximal areas as well as in the mid medial area. BMD decreased in the proximal medial and mid lateral areas. The concept of metaphyseal ingrowth was confirmed, but distal bony reactions need further investigation.
