ABSTRACT:
An prosthesis for allowing natural ball and socket type movement, as in a hip or shoulder. A femoral component having a ball at one extremity is engaged with an acetabular component having a hemispherical cup to receive the ball. A ligamentous material extends from a port in the hemispherical cup to a port in the ball to apply a resistive force to resist any dislocating force, the resistive force varying in proportion to the movement of the femoral component from a natural and relaxed position in relation to the acetabular component.
