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. The Novation Element Press-Fit Femoral Stem is intended for press-fit fixation.

Device Story

Novation Element Press-Fit Femoral Stem is an orthopedic implant for hip arthroplasty. Device features modified trapezoidal cross-sectional shaft geometry and added horizontal grooves to facilitate press-fit fixation within host bone. Implanted by surgeons using standard class I orthopedic instrumentation. Device creates interference fit with host bone to provide stability. Intended to restore hip function and mobility in patients with degenerative or traumatic hip conditions. Performance verified through engineering evaluations and bench testing; no clinical data required for this modification.

Clinical Evidence

Bench testing only.

Technological Characteristics

Femoral stem prosthesis for uncemented press-fit fixation. Features modified trapezoidal cross-sectional geometry and horizontal shaft grooves. Materials, sterilization, and packaging are identical to predicate devices. Implantation utilizes standard class I orthopedic instrumentation.

Indications for Use

Indicated for skeletally mature patients 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, 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.

Predicate Devices

• HA coated MCS Total Hip System (K990197)
• 12/14 Acumatch Press-Fit Femoral Stem (K041906)

### DESCRIPTION OF DEVICE MODIFICATIONS

The proposed Exactech Novation Element Press-Fit Femoral Stem is a modification of the HA Coated MCS Total Hip System cleared through premarket notification #K990197 and 12/14 Acumatch Press-Fit Femoral Stem cleared through premarket notification #K041906.

The predicate and proposed devices have the same intended use and basic fundamental scientific technology and share the following similarities:

- · the same indications for use
- · the same basic design features
- · incorporate the same materials
- · the same shelf life
- · are packaged and sterilized using the same materials and processes

The only modifications to the technological characteristics of the predicate devices are:

- . The trapezoidal cross-sectional geometry of the shaft has been slightly altered.
- Horizontal grooves have been added to the shaft .

Standard orthopedic instrumentation (FDA class I) is used for implantation of the Novation Element Press-Fit Femoral Stem. These press-fit femoral components are designed such that an interference condition is created between the implant and host bone.

#### INDICATIONS

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.

The Novation Element Press-Fit Femoral Stem is intended for press-fit fixation.

#### Substantial Equivalence

Testing and engineering evaluations were conducted verifying that the performance of the new Novation Element Press-Fit Femoral Stem is adequate for anticipated in vivo use. In addition to the design similarities listed above, these results demonstrate that the proposed device is substantially equivalent to the identified predicate devices.
