No
The 510(k) summary describes a system of bone plates and screws for internal fixation. There is no mention of software, algorithms, image processing, or any terms related to AI or ML. The performance studies focus on mechanical properties and biocompatibility, not algorithmic performance.

Yes
The device is used for internal fixation of fractures and reconstruction of bones, which are therapeutic interventions aimed at restoring function and healing.

No.

The device is an internal fixation system (bone plates and screws) used for the treatment of fractures, osteotomies, and other bone-related conditions, not for diagnosing them.

No

The device description explicitly states that the device is comprised of bone plates and bone screws made of titanium alloy, which are physical hardware components.

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

Here's why:

  • Intended Use/Indications for Use: The intended use is clearly described as "internal fixation" for fractures, osteotomies, arthrodesis, replantations, and reconstructions of bones in the hand, wrist, foot, and ankle. This is a surgical procedure, not a diagnostic test performed on samples taken from the body.
  • Device Description: The device is described as bone plates and screws made of titanium alloy, used as a "temporary internal stent" to stabilize bone fractures. This is a medical device used for treatment, not for diagnosis.
  • 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 to perform tests on samples taken from the body to provide information about a person's health. This device is an implantable medical device used for surgical repair.
