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. Cemented femoral stems and cemented acetabular cups are intended for cemented fixation only. Press-fit femoral stems and acetabular cups are intended for press-fit fixation. Femoral heads and endoprostheses are intended for use in cemented and press-fit applications.

Device Story

Exactech Novation Element Press-Fit Femoral Stem is a prosthetic hip component for uncemented, press-fit fixation. Device is a modification of predicate K080980, featuring updated neck geometry and alternative hydroxyapatite (HA) coating suppliers. Implanted by orthopedic surgeons in clinical settings during primary or revision hip arthroplasty. Device restores hip joint function and mobility in patients with degenerative or traumatic hip conditions. Engineering evaluation and mechanical fatigue testing confirm equivalence to predicate.

Clinical Evidence

Bench testing only. Engineering evaluations confirmed geometric correspondence to femoral anatomy. Mechanical fatigue testing demonstrated strength equivalent to comparable legally marketed femoral stems. HA coating characterization compared against FDA guidance.

Technological Characteristics

Titanium alloy femoral stem with hydroxyapatite (HA) coating. Press-fit fixation. Gamma radiation sterilization (SAL 10^-6). 5-year shelf life. No software or electronic components.

Indications for Use

Indicated for skeletally mature individuals undergoing primary hip replacement for osteoarthritis, rheumatoid arthritis, osteonecrosis, post-traumatic degenerative hip problems, or proximal femoral fractures. Also indicated for ankylosing spondylitis, congenital hip dysplasia, revision of failed reconstructions with sufficient bone stock, and restoration of mobility after fusion.

Regulatory Classification

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® Novation® Element Press-Fit Femoral Stem Special 510(k) - 510(k) Summary of Safety and Effectiveness

### Device Description:

The proposed Exactech Novation Element Press-Fit Femoral Stems are a modification of the Exactech Novation Element Press-Fit Femoral Stems cleared through premarket notification #K080980.

The predicate and proposed devices have the same intended use and the same basic fundamental scientific technology.

The modified devices share the following similarities with predicate devices:

- The same design features (e.g. stem geometry, femoral head taper design, stem . insertion feature)
- The same materials (titanium alloy, hydroxyapatite coating) .
- The same shelf life (5 years), and ●
- Are packaged and sterilized using the same materials and processes (gamma . radiation sterilization to a sterility assurance level of 10°).

This submission proposes expanding the scope of Novation Element femoral stems by adding new components with modified neck geometry and adding alternative coating suppliers.

#### Substantial Equivalence Conclusion:

The following engineering analyses were conducted to demonstrate substantial equivalence of the proposed device to the predicate Novation Element Press-Fit Femoral Stems:

- An engineering evaluation to determine that the geometric features of the . proposed device correspond to the anatomical features of the femur.
- Mechanical testing to confirm that the proposed device, under worst case . conditions, has fatigue strength equivalent to other comparable legally marketed femoral stems.
- A comparison of the HA coating characterization information of predicate and . proposed devices as outlined in the FDA guidance document "510(K) Information Needed for Hydroxyapatite Coated Orthopedic Implants".

In addition to the design similarities listed above, the results demonstrate that the proposed device is substantially equivalent to the predicate device.
