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. Novation® press-fit femoral stems are intended for press-fit fixation. Press-fit femoral stems without hydroxyapatite (HA) coating may also be used with bone cement at the discretion of the surgeon.

Device Story

The Novation 12/14 Press-Fit Femoral Stem is a prosthetic hip component designed for implantation into the femur. It functions as a replacement for the femoral head and neck, providing a structural interface for hip joint reconstruction. The device is intended for press-fit fixation within the femoral canal, though non-HA coated versions may be used with bone cement at the surgeon's discretion. It is used by orthopedic surgeons in a clinical/surgical setting. The device features a circulo-trapezoidal cross-section, a 12/14 taper for head attachment, and is available in various sizes with standard or extended offsets. A distally splined model is included. The device restores joint mobility and addresses degenerative conditions or fractures. It is manufactured from titanium alloy with plasma spray and hydroxyapatite coating.

Clinical Evidence

Bench testing only. Evidence includes ISO 7206-8 empirical fatigue testing and engineering analyses to verify the safety and performance of the modified femoral stem design compared to the predicate device.

Technological Characteristics

Materials: Titanium alloy, commercially pure titanium plasma spray, hydroxyapatite coating. Design: Circulo-trapezoidal cross-section, 12/14 femoral head taper, angled neck flat geometry. Sterilization: Gamma radiation (SAL 10^-6). Shelf life: 5 years. Standards: ISO 7206-8 (fatigue testing).

Indications for Use

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

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 12/14 Press-Fit Femoral Stems

### 510(k) Summary of Safety and Effectiveness Special 510(k)

The modified Novation femoral stems share the following similarities to the predicate AcuMatch femoral stems:

- the same indications for use, .
- similar design features (e.g. neck angle, femoral head taper design (12/14), neck . flat geometry (angled), offsets - standard and extended).
- the same materials (titanium alloy, commercially pure titanium plasma spray and . 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 (SAL) of 10").

This Special 510(k) application supports the following design changes:

- The trapezoidal cross-sectional area was modified to a circulo-trapezoidal . geometry.
- A change to the sizing range and differential. .
- A distally "splined" model was added to the product line. .
- Change in plasma coating application area. .

#### Substantial Equivalency Conclusion:

A risk analysis was performed to assess the impact of the modifications on the safety of the Novation femoral stem design. Based on successful completion of design control activities for the Exactech Novation 12/14 Press-Fit Plasma Femoral Stems, we propose that they are substantially equivalent to the Exactech AcuMatch 12/14 P-Series Plasma Press-Fit Femoral Stems cleared through premarket notification #K041906. Supporting verification activities include ISO 7206-8 empirical fatigue testing and engineering analyses.
