3 Terms, Definitions and Classification

3.1 Terms and definitions
For the purposes of this standard, the terms and definitions established in ISO 21534 and ISO 7206-1 and the following ones apply.
3.1.1
Hip joint replacement
Implant used to replace one or both of the articulating surfaces of the hip joint.
3.1.2
Total hip joint replacement
Implant comprising a femoral component and an acetabulum component intended to replace both of the articulating surfaces of the hip joints.
3.1.3
Partial hip joint replacement
Implant comprising a femoral component intended to replace the femoral articulating surface of the hip joint.
Note: partial hip joint replacement implants incorporate either a bipolar or a unipolar head.
3.1.4
Acetabulum replacement
Implant comprising an acetabulum component intended to replace acetabulum articulating surface of the hip joint.
3.1.5
Femoral component
Part of a total or partial hip joint replacement which is intended to be attached to the femur.
3.1.6
Acetabulum component
Implant of monobloc or modular construction intended to be fixed to the prepared biological acetabulum.
3.1.7
Bipolar head
Part of a femoral component with a concave (inner) surface intended to articulate with the spherical head of the femoral component and a convex (outer) spherical surface intended to articulate with the biological acetabulum.
3.1.8
Unipolar head
Head of a femoral component intended to articulate with the biological acetabulum.
3.1.9
Module component
Femoral or acetabulum component which is assembled by the user from a number of sub-components.
3.1.10
Monobloc component
Femoral or acetabulum component which is supplied as a single unit.
3.2 Classification
3.2.1 Product classification
