## Intended Use

All Exactech Hip Systems are indicated for use in skeletally mature individuals undergoing primary surgery for hip replacement due to osteoarthritis, rheumatoid arthritis, osteonecrosis, post-traumatic degenerative problems of the hip, and for treatment of proximal femoral fractures where prosthetic replacement is determined by the surgeon as the preferred treatment. Components of Exactech Hip Systems are also potentially indicated for ankylosing spondylitis, congenital hip dysplasia, revision of failed previous reconstructions where sufficient bone stock is present, and to restore mobility resulting from previous fusion.

## Device Story

Ziramic™ Zirconia 12/14 Femoral Head is a prosthetic component for hip replacement systems. Device functions as a bearing surface in total hip arthroplasty; interfaces with 12/14 femoral stems and acetabular cup liners. Used in clinical settings by orthopedic surgeons during primary or revision hip surgery. Input is mechanical loading from patient movement; output is articulation within the hip joint. Benefits include restoration of mobility and treatment of degenerative hip conditions. Modification from predicate involves expanded compatibility with AcuMatch® and Novation™ 12/14 cemented femoral stems.

## Clinical Evidence

Bench testing only. Engineering evaluations were conducted to verify performance under anticipated in vivo loading conditions when mated with Exactech cobalt chrome alloy 12/14 femoral stems.

## Technological Characteristics

Material: Zirconia ceramic. Interface: 12/14 taper. Compatibility: Restricted to UHMWPE or metal-backed UHMWPE acetabular liners. Mechanical device; no software or energy source.

## Regulatory Identification

A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.

# Exactech® Ziramic™ Zirconia 12/14 Femoral Heads Special 510(k) -Summary of Safety and Effectiveness

#### CONTRAINDICATIONS

Exactech Hip Systems are contraindicated in patients with active infection, patients without sufficient bone stock to allow appropriate insertion and fixation of the prosthesis, in neuromuscular disorders that do not allow control of the hip joint, and in patients whose weight, age, or activity level would cause the surgeon to expect early failure of the system.

The Zirconia Ceramic Head is contraindicated for use with any other acetabular cup liner than an ultra high molecular weight polyethylene (UHMWPE) liner or a metal backed UHMWPE liner.

The safety and effectiveness has not been shown for the use of Exactech stems when used with ceramic on ceramic acetabular cups.

## Special 510(k) Modifications

The Exactech® Ziramic™ Zirconia 12/14 Femoral Heads were modified from the predicate as follows:

- The mating parts scope was expanded to include: . Exactech® AcuMatch® 12/14 Cemented Femoral Stems Exactech® Novation™ 12/14 Cemented Femoral Stems
- . The package insert was updated to clarify femoral head and femoral stem compatibility

## Conclusion:

Testing and engineering evaluations were conducted to verify adequate performance of the Exactech® Ziramic™ Zirconia 12/14 Femoral Heads for anticipated in vivo loading when mated with Exactech cobalt chrome alloy 12/14 Femoral Stems. Based on successful results we conclude that the proposed 12/14 Ziramic™ Zirconia 12/14 Femoral Heads devices are substantially equivalent to the predicate design (#K050398).
