Intended Use

APTUS® Wrist Arthrodesis Plates are indicated for wrist arthrodesis.

Device Story

APTUS® Wrist Arthrodesis Plates are titanium locking plates used for internal fixation during wrist arthrodesis procedures. The system consists of plates of various sizes secured with previously cleared titanium screws. Used in clinical settings by orthopedic surgeons, the device provides mechanical stabilization of the wrist joint to facilitate fusion. The plates function by providing a rigid construct to hold bones in place during the healing process, potentially improving patient outcomes by ensuring proper alignment and stability. The device is a mechanical implant; it does not involve electronic inputs, software, or automated processing.

Clinical Evidence

Bench testing only. Evidence includes dimensional analysis, moment of inertia analysis, and screw pull-out testing to compare the subject device's mechanical performance to predicate devices.

Technological Characteristics

Titanium locking plates; mechanical fixation; various sizes; sterilized using standard methods; no software or electronic components.

Indications for Use

Indicated for wrist arthrodesis in patients requiring internal fixation for 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.

### INTENDED USE

APTUS® Wrist Arthrodesis Plates are indicated for wrist arthrodesis.

### DEVICE DESCRIPTION

The APTUS® Wrist Arthrodesis Plates system is intended to be used for internal fixation of wrist fusions and consists of three titanium locking plates. The plates are secured using previously cleared titanium screws. APTUS Wrist Arthrodesis Plates are provided in various sizes.

# EQUIVALENCE TO MARKETED DEVICE

APTUS® Wrist Arthrodesis Plates are substantially equivalent in indications and design principles to the following predicate devices, each of which has been determined by FDA to be substantially equivalent to pre-amendment devices:

Kinetikos Medical Inc., KMITM Wrist Fusion System, cleared under K990094,

Synthes (USA), Synthes (USA) Small Titanium Wrist Fusion Plate cleared under K023879,

Synthes (USA), Synthes (USA) LCP Wrist Fusion Plates cleared under K042355,

Synthes (USA), Synthes Straight Wrist Fusion Plate cleared under K011458,

Synthes (USA), Synthes USA) Wrist Fusion Plate cleared under K000558, and

Medartis, Inc., APTUS® Titanium Fixation System cleared under K051567.

The subject device and the predicate devices have the same intended use and have the same technological characteristics. The subject and predicate devices are all fabricated from the same or similar materials and share similar design characteristics. The subject and predicate devices encompass the same or comparable ranges of physical dimensions, are packaged using the same or similar materials, and are to be sterilized by the same methods. Any differences in the technological characteristics do not raise new issues of safety or efficacy.

Performance data provided to demonstrate substantial equivalence include detailed dimensional analysis of the subject and predicate plate designs, and moment of inertia analysis of the subject and predicate plate design. Screw pull-out testing and engineering analysis were performed to demonstrate that the distal attachment of the subject device (carpal bones) is comparable to that of the predicate device plates (third metacarpal bone).

Overall, APTUS Wrist Arthrodesis Plates have the following similarities to the predicate devices:

- . have the same intended use,
- use the same operating principles, ●
- incorporate the same basic designs, .
- incorporate the same or very similar materials, and .
- t have similar packaging and are sterilized using the same materials and processes.

Dear Dr. Thomas:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act.
