## Indications for use
The subject acetabular liners are single-use devices intended for use in total hip replacement. They are intended for mechanical assembly to predicate Trident series acetabular shells. (The predicate Trident series shells are intended for cementless fixation.) Indications: Painful, disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis, or late stage avascular necrosis. Revision of previous failed femoral head replacement, cup arthroplasty or other procedure. Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results. Where bone stock is of poor quality or is inadequate for other reconstructive techniques as indicated by deficiencies of the acetabulum.
