REDUCTION OF THE DEVELOPMENT OF STRIPE WEAR ON INSERTS FOR HIP JOINT PROSTHESES BY MODIFYING THE GEOMETRY OF THE TRANSITION BETWEEN THE FACE AND SPHERICAL RECESS |
摘要 |
<p>A socket insert of a hip joint prosthesis having a spherical-indentation-shaped recess in which a spherical head of a femur is mounted. The spherical indentation has a run-in zone which ends on one side with a circular arc tangentially in an end face of the socket insert and extends on another side as far as the run-in edge. Between a start of the circular arc with a radius of the length (RE) and the run-in edge of the spherical indentation with the radius of the length (RK) the run-in zone forms a curve, the function of which is continuously differentiated twice at every point.</p> |
