Device Story

TriMed Wrist Fixation System 3 consists of metallic bone plates, screws, pins, and wire forms used for orthopedic trauma fixation. Devices are anatomically shaped to stabilize bone fragments in the distal radius and ulna. System includes Volar Plates (fixed-angle or bearing), Radial Peg Plates, Ulnar Peg Plates, Pin Plates, Hook Plates, and Buttress Pins. Implants are used by orthopedic surgeons in clinical/surgical settings to provide mechanical support for bone healing. Surgeons select appropriate plate/pin configuration based on fracture pattern; hardware is secured using 2.4mm locking/non-locking screws or 1.1mm k-wires. System provides intraosseous support and stabilization of bone fragments, facilitating anatomical alignment and healing. Devices are supplied non-sterile and require sterilization by the user.

Clinical Evidence

No clinical data. Substantial equivalence determined via bench testing and engineering analysis.

Technological Characteristics

Implants manufactured from 316L Stainless Steel (ASTM F138/139). System includes plates, screws, pins, and wire forms. Mechanical performance tested per ASTM F382 (plates) and ASTM F543-17 (screws). Biocompatibility per ISO 10993-1:2018. Supplied non-sterile.

Indications for Use

Indicated for patients requiring surgical fixation of fractures, non-unions, or osteotomies of the distal radius, distal ulna, radial column, or dorsal ulnar cortex of the distal radius.

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.

Dear David Anderson:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

- Engineering analysis to predicates (Hook Plates, Pin Plates and Buttress Pins) ●
- Cytotoxicity, Sensitization and Irritation testing in accordance with ISO 10993-1:2018 (All ● implants)
- All system screws were tested per ASTM F543-17 for: ●
- Torsional Strength O
- O Driving Torque

### Substantial Equivalence: - Clinical Evidence

Clinical testing was not necessary for the determination of substantial equivalence.

#### Substantial Equivalence - Conclusions

TriMed Wrist Fixation System 3 devices are substantially equivalent to the predicate devices in which basic design features, intended uses, indications for use, manufacturing, packaging, and labeling are the same. Any differences between the proposed device and the predicate device are considered minor and do not raise different questions concerning safety or effectiveness.

The submitted mechanical testing data and engineering analyses show the subject devices are substantially equivalent to that of the predicate devices for the desired indications.

Based on the indications for use, technological characteristics, and the summary of data submitted, TriMed Inc. has determined that the proposed devices are substantially equivalent to the currently marketed predicate device.
