Intended Use
The BABY GORILLA®/GORILLA® Bone Plates and Bone Screws of the BABY GORILLA®/GORILLA® Plating System are indicated for use in stabilization of fractures or osteotomies; intra and extra articular fractures, joint depression, and multi-fragmentary fractures; revision procedures, joint fusion and reconstruction of small bones of the toes, feet and ankles including the distal tibia, talus, and calcaneus. The system can be used atric patients. In addition, the non-locking, titanium screws and washers are indicated for use in bone reconstruction, osteotomy, arthrodesis, joint fusion, fracture repair and fracture fixation, appropriate for the device.
Device Description
The BABY GORILLA®/GORILLA® implants are lower extremity fixation systems. Gorilla Plates are offered in “mini” and “standard” set sizes in a variety of shapes based upon the anatomical fixation required. Screws are also offered in “mini” and “standard” sets and, in addition, in locking and non-locking versions. Size- matched washers are available for use with the non- locking screws when the latter are used for fixation without the plates. Size-matched plate washers are also available for use with plate holes when there is no desire to use a screw.
More Information

Not Found

No
The document describes a system of bone plates and screws for fracture fixation and reconstruction. There is no mention of AI or ML in the intended use, device description, or performance studies.

Yes
The device is indicated for stabilizing fractures, fusing joints, and reconstructing bones, which are therapeutic interventions.

No

The device is described as an implantable system for stabilizing fractures and performing reconstructive procedures, not for diagnosing conditions.

No

The device description explicitly states it consists of "Bone Plates and Bone Screws" and "implants," which are physical hardware components, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for the "stabilization of fractures or osteotomies; intra and extra articular fractures, joint depression, and multi-fragmentary fractures; revision procedures, joint fusion and reconstruction of small bones of the toes, feet and ankles". This describes a surgical implant used in vivo (within the body) for structural support and repair.
  • Device Description: The description details "lower extremity fixation systems" consisting of "plates" and "screws". These are physical implants designed to be surgically placed.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment.

IVD devices are used in vitro (outside the body) to analyze biological samples. This device is a surgical implant used in vivo.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Engineering analysis is presented to provide evidence that the original testing and subsequence performance is not adversely affected by the geometry of the modified plates, screws, and washers.

The results of the analysis demonstrated the modified designs are substantially equivalent to the predicate devices.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

Dear Eric Lintula:

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 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

Characteristics: | The modified Gorilla plates, screws, and washers possess
the same technological characteristics as the predicate
devices. These include:
performance, basic design, material, manufacturing and sizes (dimensions are comparable to those offered
by the predicate systems). Therefore, the fundamental scientific technology of the
modified Gorilla Plates, Screws, and Washers is similar
