## Intended Use

The titanium alloy cortical bone screws presented in this submission are intended for long and small bone fracture fixation.

## Device Story

4.0mm titanium alloy bone screws (partially and fully threaded) with manual orthopedic instruments; used for long and small bone fracture fixation; operated by surgeons in clinical/OR settings; provides mechanical stabilization of bone fragments; benefits include secure fixation of fractures.

## Clinical Evidence

Bench testing only; fatigue testing performed on titanium alloy screws. No clinical data provided.

## Technological Characteristics

Titanium alloy material; 4.0mm diameter; partially and fully threaded configurations; manual orthopedic instrumentation; manufactured per ISO and German DIN standards.

## Regulatory 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.
