Intended Use
The Trauma Internal Fixation System is used for fracture fixation in the proximal and distal regions of the femur. In particular, indications for use in adult and pediatric patients are as follows: Adult indications: - Intracapsular fractures of the femoral neck. (For high subcapsular fractures it may be more prudent to select a prosthesis in lieu of internal fixation to reduce the risk of a nonunion or avascular necrosis of the femoral head). - Trochanteric or subtrochanteric fractures with appropriate additional postoperative precautions about weight bearing and more than sedentary activity. - Osteotomics for patients with discases or deformities of the hip. - Hip arthrodesis. - Supracondylar fractures and distal femoral fractures using a supracondylar plate. - Ipsilateral femoral shaft/neck fractures (IMHS only). Pediatric indications: - Congenital coxa vara. - Congenital dislocation of the hip. - Subluxation or dislocation secondary to neurologic disorders such as cerebral palsy, myelomenigocele, poliomyelitis, etc. Usually valgus-anteversion deformities. - Coxa plana (Legg-Calve-Perthes disease) for containment of the head completely within the acetabulum.
Device Description
The Compression Hip Screw is composed of a plate, lag screw, compression screw,and bone screws. The Intramedullary Hip Screw is composed of a intramedullary nail, lag screw, compression hip screw, centering sleeve, set screw and bone screws.

None

No
The device description focuses solely on the materials and components of mechanical implants for fracture fixation. There is no mention of software, algorithms, or any functionality that would suggest the use of AI or ML.

Yes
The device is used for fracture fixation, which is a therapeutic intervention aimed at treating injuries.

No.

The device's description and indications for use clearly state it is a system for fracture fixation in the femur, composed of various screws, plates, and nails. Its purpose is to physically stabilize fractures and deformities, which is a therapeutic intervention, not a diagnostic one.

No

The device description explicitly lists hardware components made of metal and plastic, such as plates, screws, and nails, which are used for fracture fixation. There is no mention of software as the primary or sole component.

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

Here's why:

  • Intended Use: The intended use clearly describes the device as being used for fracture fixation in the femur. This is a surgical procedure performed directly on the patient's body.
  • Device Description: The device is described as a system of plates, screws, and nails made from materials like stainless steel and titanium. These are all components used in surgical implants.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or treatment.

IVD devices are used in vitro (outside the body) to analyze biological samples. This device is used in vivo (inside the body) for structural support and fixation.

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
