Abstract
The present invention concerns an endoprosthesis for an artificial hip-joint, the endoprosthesis including a shank (1) having an adapter (2) at one of its ends. A ballhead (4) is fitted with a recess (6) detachably engaged by the adapter (2) while retaining the ballhead. The adapter (2) and the recess (6) are cylindrical, whereby the ballhead (4) is axially adjustable. A device is provided for retaining the ballhead (4) in various axial positions relative to the adapter (2). Accordingly, the ballhead (4) is adjustable with respect to its axial position and thereby its distance from the adapter (2) or the shank (1) is likewise adjustable. This feature eliminates the need to stock different ballheads matching different anatomic particulars.
