More Information

Not Found

No
The device description and performance studies focus on the mechanical properties of a bone screw, with no mention of AI or ML.

Yes
The device is intended for fixation of bone fractures or bone reconstructions, which is a therapeutic purpose.

No
The device is a screw intended for fixing bone fractures or reconstructions, which is a therapeutic function rather than a diagnostic one.

No

The device description explicitly states it is a "cannulated thread-head screw made of a Titanium alloy," which is a physical hardware implant.

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

Here's why:

  • Intended Use: The intended use is for the fixation of bone fractures or bone reconstructions and fixing elective osteotomies in the foot. This is a surgical implant used directly on the patient's body.
  • Device Description: The device is a cannulated thread-head screw made of a titanium alloy. This is a physical implant.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue) in vitro (outside the body) to provide information about a physiological state, health, or disease.

IVD devices are used to perform tests on samples taken from the body, not implanted within the body for structural support or fixation.

§ 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.

SUMMARY OF STUDIES:

The SCARF THREAD-HEAD™

SCREW is a cannulated thread-head screw made of a Titanium alloy. Screws come in lengths of 10-32 mm in 2 mm increments.

The SCARF THREAD-HEAD™

SCREW is intended to be implanted for fixation of bone fractures or bone reconstructions.

The SCARF THREAD-HEAD™

SCREW is indicated for fixing the elective osteotomies of the mid-foot bones and the metatarsal and phalanges of the foot only.

The SCARF THREAD-HEAD™

SCREW is substantially equivalent to the Medinov-AMP Scarf Screw (K931155), the Herbert-Whipple Bone Screw (Zimmer) (K792022) and the M3 Screw System (Osteomed) (K924018, 924138).

Both the SCARF THREAD-HEAD™

SCREW, the Scarf Screw and the Herbert-Whipple Bone Screw have the same intended use and all are indicated for fixing small fractures or osteotomies. All are made from Titanium alloys. The SCARF THREAD-HEAD™ SCREW and Scarf Screws are threaded on nearly all their length with the same thread pitch. Both have a thread head and a hexagonal socket. The Scarf screw is not cannulated; the Herbert-Whipple screw is cannulated and is topped with a hexagonal socket.

Rupture torque of the SCARF THREAD-HEAD™ SCREW was compared with requirements of the French Standard Nº NF-F-90-414 and found to have a resistance to torsion in compliance with the selected Standard.
