## Indications for Use

All Exactech Hip Systems are indicated for use in skeletally mature individuals undergoing primary surgery for total hip replacement due to osteoarthritis, rheumatoid arthritis, osteonecrosis, ankylosing spondylitis, congenital hip dysplasia, 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 revision of failed previous reconstructions where sufficient bone stock is present and to restore mobility resulting from previous fusion. The AcuMatch C-Series Femoral component is intended to be used with bone cement.

## Device Story

The Exactech AcuMatch C-Series Cemented Femoral Component (Size 0) is a metallic hip prosthesis designed for cemented implantation. It is used by orthopedic surgeons in clinical settings during total hip arthroplasty or revision surgery. The device is forged from Cobalt Chromium Molybdenum alloy and features a satin finish, a collar for cement pressurization, and a trapezoidal distal geometry. It may be used with optional PMMA centralizers to ensure proper stem placement. The device replaces the femoral head and neck to restore hip function and mobility. Clinical benefit is derived from the restoration of joint mechanics in patients with degenerative hip conditions or fractures. The surgeon selects the appropriate size based on patient anatomy and bone stock.

## Clinical Evidence

Bench testing only. Three-point bending fatigue testing was performed to demonstrate that the strength of the C-Series size 1 components is sufficient to support expected in vivo load applications.

## Technological Characteristics

Material: Cobalt Chromium Molybdenum alloy (ASTM F 799-96). Design: Cemented femoral stem with collar and trapezoidal distal cross-section. Sterilization: Gamma radiation (25–37 kGy). Packaging: PETG trays, Tyvek lids, Plastizote LD45 foam inserts.

## Regulatory Identification

A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

# Substantial Equivalence Information:

The Exactech AcuMatch C-Series Cemented Femoral (size 0) component has similar indications and contraindications as other femoral components legally marketed in the United States. In addition the C-Series has similar technological features to other devices, most notably Exactech's AuRA and L-Series femoral components. In addition, the proposed C-Series component is similar to femoral components currently marketed by other manufacturers. These include the "Conquest FX" and "Spectron" by Smith & Nephew and the "PFC" by Depuy.

#### Intended Use / Indications:

All Exactech Hip Systems are indicated for use in skeletally mature individuals undergoing primary surgery for total hip replacement due to osteoarthritis, rheumatoid arthritis, osteonecrosis, ankylosing spondylitis, congenital hip dysplasia, 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 revision of failed previous reconstructions where sufficient bone stock is present and to restore mobility resulting from previous fusion.

The AcuMatch C-Series Femoral component is intended to be used with bone cement.

#### 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.

#### Device Description:

C-Series Femoral Stem Components are made from Cobalt Chromium Molybdenum alloy forged per ASTM F 799-96. The components have a satin finish and are intended for cemented applications only. The stems have a collar to enhance cement pressurization and stress transmission to the medial femoral neck. There is a proximal to distal taper and trapezoidal cross-sectional geometry in the distal region. C-Series stems may be used with optional distal PMMA centralizers to ensure central stem placement.

#### Performance Data Summary:

Three point bending fatigue testing showed that the strength of the C-Series size 1 components is sufficient to support expected in vivo load applications.

Dear Ms. Simpson:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
