• Attributes: Therapeutic

Intended Use

The indications for use for Biomet hip replacement prosthesis include: 1) noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis; 2) rheumatoid arthritis; 3) correction of functional deformity; 4) treatment of non-union, femoral neck fracture, and throchanteric fractures of the proximal femur with head involvement, unmanageable using other techniques; and 5) revisions of hip replacement components. Standard surgical and rehabilitative procedures are indicted with this device. This device is for use with bone cement.

Device Story

Color Buffed Cemented Femoral is a modular hip prosthesis designed to replace diseased or damaged femoral necks. Device consists of a distally tapered femoral stem with PMMA spacers to enhance stability within the cement mantle; modular head attaches to trunion to articulate with acetabular components. Stem features reduced superior lateral for insertion ease and reduced medial collar for range of motion and stability. Straight stem design eliminates need for left/right configurations. Used by orthopedic surgeons in clinical settings for total hip arthroplasty. Provides articulating surface for hip joint, restoring function and stability in patients with degenerative joint disease or fractures.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Cemented femoral hip prosthesis; modular design; includes PMMA spacers for cement mantle stability; distally tapered stem; straight configuration; metallic construction.

Indications for Use

Indicated for patients with noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures (non-union, femoral neck, trochanteric) requiring hip replacement or revision. Requires use with bone cement.

Regulatory Classification

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).

Trade Name: Color Buffed Cemented Femoral

Classification Name: Hip joint metal/polymer semi-constrained cemented prosthesis (CFR 888.3350).

Device Description: The Color Buffed Cemented Femorals are designed to replace a diseased or damaged femoral neck. A modular head attaches to trunion to complete the femoral side of a total hip. The stems are indicated for cement use and are distally tapered to provide better stress distribution through the cement mantle. A reduced superior lateral insures easier insertion while maintaining proximal canal filling. A reduced medial collar provides greater range of motion, stability, and prevention of component subsidence. Each stem is straight, thus eliminating the need for a left and right configurations. The stems utilize a modular head to provide an articulating surface with any commercially available acetabular component. These components are intended for use with bone cement, and as such. have PMMA spacers added to the stem to enhance stability within the cement mantle.

Potential Risks: The potential risks associated with this device are the same as with any joint replacement device. These include, but not limited to:

Reaction to bone cement Deformity of the joint Cardiovascular diseases Fracture of the cement Implant loosening/Migration Tissue growth failure

Blood vessel damage Soft tissue imbalance Delayed wound healing Metal sensitivity Fracture of the components Nerve damage

Bone fracture Infection Hematoma Dislocation Excessive wear

Dear Ms. Hufziger Binkley:

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.
