## Indications for use
The Apex ARC Hip Stem is intended for use as the femoral component of a primary, or revision total hip replacement when used with the Apex Interface Acetabular System. The Apex Interface Acetabular System articulates with the Apex Modular Femoral Head (Cobalt Chromium or Ceramic). The femoral hip stem is intended for uncemented fixation and single use implantation. These prostheses may be used for hip arthroplasty to treat the following conditions, as appropriate: * Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; * Rheumatoid arthritis; * Correction of functional deformity; * Congenital dislocation; * Revision procedures where other treatments or devices have failed; * Femoral neck and trochanteric fractures of the proximal femur. The Apex Hip System ARC Hip Stem is also intended for use in hemiarthroplasty when used with the Apex Bipolar Head. The Apex Hip System Bipolar Head is intended for use in combination with an Apex Hip System femoral stem for uncemented primary or revision hemiarthroplasty of the hip. This prosthesis may be used for the following conditions, as appropriate: * Femoral neck and trochanteric fractures of the proximal femur; * Osteonecrosis of the femoral head; * Revision procedures where other treatments or devices for these indications have failed.
