Intended Use

The Nexa bone screw system provides fixation of fractures, fusions, or osteotomies of bones of the hand and foot.

Device Story

Nexa bone screw system consists of titanium (6AL-4V ELI) screws; used for fixation of fractures, fusions, or osteotomies in hand and foot bones. Device implanted by surgeons in clinical settings. Screws provide mechanical stabilization of bone segments to facilitate healing. System provided in 6 sizes. No software or algorithmic components involved.

Clinical Evidence

No clinical data provided; substantial equivalence based on design, material, and intended use comparisons to predicate device.

Technological Characteristics

Titanium 6AL-4V ELI alloy; screw-type bone fixation fastener; 6 available sizes; single-use; non-sterile (implied by standard orthopedic practice); mechanical fixation principle.

Indications for Use

Indicated for fixation of fractures, fusions, or osteotomies of bones of the hand and foot in patients requiring surgical bone stabilization.

Regulatory Classification

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.
