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. Press-fit components without hydroxyapatite (HA) coating may also be used with bone cement at the discretion of the surgeon. Femoral heads and endoprostheses are intended for use in cemented and press-fit applications.

Device Story

The Novation CFS Press-Fit and Cemented Femoral Stems are orthopedic implants used in hip arthroplasty. The press-fit version features a calcar collar, grit-blast body, and satin-finish neck. The cemented version is cast cobalt chrome alloy with a satin-finish neck. Both utilize a modified 12/14 femoral head taper connection. These devices are implanted by orthopedic surgeons in a clinical/OR setting to replace the femoral component of the hip joint. They interface with previously cleared femoral heads and unipolar sleeves. The device restores joint function and mobility in patients with degenerative hip conditions or fractures. Clinical benefit is derived from the mechanical replacement of the diseased or damaged femoral head and neck, facilitating joint articulation and weight-bearing.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: Cobalt chrome alloy. Design: Femoral stems with 12/14 taper connection; press-fit version includes calcar collar and grit-blast body; cemented version is cast. Sterilization: Same as predicate devices. Connectivity: None (mechanical implant).

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 femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth.

Predicate Devices

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. Press-fit . components without hydroxyapatite (HA) coating may also be used with bone cement at the discretion of the surgeon.
- . Femoral heads and endoprostheses are intended for use in cemented and press-fit applications.

### Device Description:

The proposed Novation CFS Press-Fit and Cemented Femoral Stems are modifications to the existing Novation Press-Fit and Novation Cemented Plus femoral stem devices previously cleared in K042842 and K083392, respectively. The proposed Novation CFS Press-Fit stem has the same general design features as the predicate device. The modifications include the addition of a calcar collar, grit-blast body, and a satin finish neck. The proposed CFS Cemented stem has the same general design features as the Novation Cemented Plus stem, but the proposed stems are cast instead of forged cobalt chrome alloy and the neck is a satin finish. Both proposed stems contain a modified 12/14 femoral head taper connection.

The proposed stems mate with previously cleared 12/14 Co-28Cr-6Mo femoral heads (K041906), Zirconia ceramic femoral heads (K050398 and K060107) and 12/14 Unipolar Sleeves (K010081). The proposed stems are not compatible with alumina ceramic femoral heads (K032964 and K051682).

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
- · similar design features
- · incorporate the same materials
- · the same shelf life
- · are packaged and sterilized using the same materials and processes.

### Substantial Equivalence Conclusion:

Results of engineering studies referenced in this 510(k) submission demonstrate that the proposed Novation CFS Press-Fit and Cemented Femoral Stems are substantially equivalent to the cleared predicate devices.
