Cemented or non-cemented total hip replacement in cases of:

1. Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis

2. Rheumatoid arthritis

3. Correction of functional deformity

4. Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques.

5. Revision procedures where other treatment or devices have failed.

The Indications for use of the constrained liners compatible with this system are as follow:

The devices are intended for general use in skeletally mature individuals undergoing primary and/or secondary revision surgery at high risk of hip dislocation due to a history of prior dislocation, bone loss, joint or soft tissue laxity, neuromuscular disease, or intra-operative instability and for whom all other options to constrained acetabular components have been considered.

Indications for use as stated in the FDA summary.
