Abstract
A femur head cap for endoprosthesis possessing a spherical shape and having a recess for partially receiving the femur head, the recess being open toward the neck of the femur. The cap is advantageous in that it can be firmly anchored to avoid rotation and tilting without the use of bone cement and further allows for simple resection to be performed so that supply of blood to the bone is not impaired.
