Intended Use
The Nexa bone screw system provides fixation of fractures, fusions, or osteotomies of bones of the hand and foot.
Device Description
The Nexa Orthopedics bone screw system consists of screws made of Titanium (6AL-4V ELI) intended to be implanted into the bones of the foot, and hand. The screws are provided in 6 sizes. The screws are used for fixation of fractures, fusions, or osteotomies of bones of the hand and foot. The design of the Nexa bone screw system is similar in shape and size to the Wright Medical Charlotte Snap-Off Screw. No new materials arc used in the development of this implant.
More Information

Not Found

No
The 510(k) summary describes a standard bone screw system made of titanium, with no mention of software, algorithms, image processing, AI, ML, or any related concepts. The description focuses solely on the physical characteristics and intended use of the screws.

No
The device is a bone screw system used for fixation of fractures, fusions, or osteotomies, which falls under surgical orthopedic implants rather than devices designed to cure, treat, mitigate, or prevent disease through non-invasive therapeutic means.

No
Explanation: The device description states its purpose is for "fixation of fractures, fusions, or osteotomies of bones," which is a treatment/surgical function, not a diagnostic one.

No

The device description clearly states it consists of screws made of Titanium, which are physical hardware components intended for implantation.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
  • Nexa Bone Screw System Function: The Nexa bone screw system is an implantable device used for the fixation of bones within the body. It is a surgical device, not a diagnostic test performed on samples.

The provided information clearly describes a surgical implant used for structural support, which is fundamentally different from the function of an IVD.

§ 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.
