Indications for Use
The KMI Wrist Fusion System is comprised of the total wrist fusion plate which is intended for wrist arthrodesis, providing fixation of small bones such as the radius and carpal bones and indicated for use in patients suffering pain and/or loss of function due to osteoarthritis, post-traumatic arthritis, fractures, revision of failed wrist fusions, segmental bone loss, or rheumatoid arthritis, and the KMI limited wrist fusion plate is intended for use in patients suffering pain and/or loss of function due to osteoarthritis, post-traumatic arthritis, fractures, revision of failed partial wrist fusions, carpal instability, or rheumatoid arthritis.
Device Story
KMI Wrist Fusion System consists of metal plates and screws used for wrist arthrodesis and fixation of small bones (radius and carpal bones). Device is used by surgeons in clinical settings to stabilize bones in patients with arthritis, fractures, or failed prior fusions. System provides mechanical fixation to facilitate bony union. No electronic or software components.
Clinical Evidence
No clinical data; bench testing only.
Technological Characteristics
Constructed of 316L stainless steel. Consists of metal plates with holes for specific screws. Mechanical fixation device. No software, electronics, or energy source.
Indications for Use
Indicated for patients suffering pain and/or loss of function due to osteoarthritis, post-traumatic arthritis, fractures, revision of failed wrist fusions, segmental bone loss, carpal instability, or rheumatoid arthritis requiring wrist arthrodesis or limited wrist fusion.
Regulatory Classification
Identification
Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

## 4. Description of Device:
The KMI Wrist Fusion System consists of metal plates with holes to accommodate specific screws and the screws, all manufactured of 316L stainless steel.
- Intended Use: The current KMI Wrist Fusion System (K990094) is intended for 5. wrist arthrodesis, providing fixation of small bones such as the radius and carpal bones and indicated for use in patients suffering pain and/or loss of function due to osteoarthritis, posttraumatic arthritis, fractures, revision of failed wrist fusions, segmental bone loss, or rheumatoid arthritis, while the KMI limited wrist fusion plate is intended for use in patients suffering pain and/or loss of function due to osteoarthritis, post-traumatic arthritis, fractures, revision of failed partial wrist fusions, carpal instability, or rheumatoid arthritis. The Howmedica ICS Mini and Small Fragment Set (K800806) is used for stabilizing fractures of the small bones of the hand, foot, ankle and elbow until bony union can occur. These intended uses are substantially equivalent and do not affect safety or effectiveness.
- 6. Technological Characteristics: The current KMI Wrist Fusion System, the KMI limited wrist fusion plate, and the Howmedica ICS Mini and Small Fragment Set consist of metal plates with holes to accommodate specific screws and the screws, all manufactured of 316L stainless steel. There are no technological characteristics that raise new issues of safety or effectiveness.

Dear Mr. Collins:
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.
