An orthopedic component having multiple layers that are selected to provide an overall modulus that is substantially lower than the modulus of known orthopedic components to more closely approximate the modulus of the bone into which the orthopedic component is implanted. In one exemplary embodiment, the orthopedic component is an acetabular shell. For example, the acetabular shell may include an outer layer configured for securement to the natural acetabulum of a patient and an inner layer configured to receive an acetabular liner. The head of a femoral prosthesis articulates against the acetabular liner to replicate the function of a natural hip joint. Alternatively, the inner layer of the acetabular shell may act as an integral acetabular liner against which the head of the femoral prosthesis articulates.

Method of manufacturing an acetabular component

Orthopedic component of low stiffness

An acetabular implant for hip replacement surgery includes a shell component and first and second alternative bearing components interchangeably engageable with the shell component to provide a choice in bearing components. The shell component has a shell component engagement mechanism suitable for engaging the first alternative bearing component. A conversion ring is also engageable with the shell component, so that a shell component/conversion ring assembly provides a second shell component engagement mechanism suitable for engagement with the second alternative bearing component.

Acetabular cup conversion ring

An acetabular implant for hip replacement surgery includes a shell component and first and second alternative bearing components interchangeably engageable with the shell component to provide a choice in bearing materials. The shell component has an engagement mechanism suitable for locking engagement with the first alternative shell component. A conversion ring is lockingly engageable with the shell component to adapt the shell component to provide an engagement mechanism suitable for locking engagement with the second alternative shell component.
