Indications
The Foundation® Bipolar hip is intended for treatment of patients who are candidates for
hemi arthroplasty of the hip because the natural femoral head and neck have been affected by osteoarthritis, inflammatory arthritis, traumatic
arthritis, rheumatoid arthritis, avascular necrosis or femoral neck fracture, and revision arthroplasty where bone loss is minimal.
This device is intended to aid the surgeon in relieving the patient of hip pain and restoring hip motion
and is intended to be used with any Encore® stem. The Foundation Unipolar femoral head is
intended for treatment of patients who are candidates for arthroplasty of the hip because the
natural femoral head and neck have been affected by osteoarthritis, inflammatory arthritis,
traumatic arthritis, rheumatoid arthritis, avascular necrosis of femoral neck fracture,
and revision arthroplasty where bone loss is minimal. These devices are intended to aid the
surgeon in relieving the patient of hip pain and restoring hip motion and are intended
to be used with any Encore stem. The unipolar femoral head is used with a modular neck adaptor sleeve.
