Read the full statement (234 words)
The subject devices are single use devices. They are intended for mechanical fixation to their mating hip stems, and can be used in cemented or cementless hip arthroplasty procedures. They can be used with all Howmedica Osteonics C-Taper* hip stems made from Titanium or CoCr alloys. When used as a total hip replacement, they are intended for use only with Howmedica Osteonics polyethylene bearing surfaces.
Indications for Use as a Bipolar
* Femoral head/neck fractures or non-unions,
* Aseptic necrosis of the femoral head,
* Osteo-, rheumatoid, and post traumatic arthritis of the hip with minimal acetabular involvement or distortion.
* Pathological conditions or age considerations that indicate a more conservative acetabular procedure and an avoidance of the use of bone cement in the acetabulum,
* Salvage of failed total hip arthroplasty.
Indications for Use as a Total Hip:
Painful disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis,
Revision of previous unsuccessful 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 in the acetabulum.
* The term "C-Taper" includes both the original C-Taper design, and the modified C-Taper design first introduced on the hip stems found Substantially Equivalent via K982032
Indications for use as stated in the FDA summary.
