The summary describes a system of plates and screws for bone fixation and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.
No
The device is a surgical system for bone fixation after osteotomies, which is a structural intervention, not a therapeutic agent or method for treating disease directly.
No
The device is a surgical system intended for the fixation of bones after osteotomies, not for diagnosing conditions.
No
The device description explicitly states the system consists of stainless steel plates and titanium alloy or stainless steel screws, which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical system for treating bone and joint deformities and malalignment through osteotomies. This is a surgical intervention, not a diagnostic test performed on samples from the human body.
- Device Description: The device consists of plates and screws made of stainless steel and titanium alloy, designed for fixation within the bone. This is consistent with a surgical implant system.
- Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.), detecting substances, or providing diagnostic information about a patient's condition based on in vitro analysis.
The SURFIX® Knee Osteotomy System is a surgical device used for orthopedic procedures.
N/A
Intended Use / Indications for Use
The SURFIX® Knee Osteotomy System is intended for open and closed wedge osteotomies of the proximal tibia and the distal femur, treatment of bone and joint deformities, and malalignment caused by injury or disease such as osteoarthritis.
The SURFIX® Knee Osteotomy System is indicated for knee osteotomies including high tibial osteotomy and femoral osteotomy in the cases of osteoarthritis of the medial tibiofemoral compartment with genu varum and lateral gonarthrosis on genu valgum. Examples Include:
- Fixation of opening wedge high tibial osteotomy,
- Fixation of fracture of the medial tibial plateau,
- Osteoarthritis of the medial tibiofemoral compartment with genu. varum,
- Fixation of closing wedge high tibial osteotomy,
- Fixation of fracture of the lateral tibial plateau,
- Distal femoral varus osteotomy,
- Lateral gonarthrosis on genu valgum.

Device Description
The SURFIX® Knee Osteotomy System consists of seven different Stainless Steel plates with a locking system between the threaded sockets of the plates and the lock screws. There are six plates for the proximal tibia and one plate for the distal femur. Their fixation is provided by Titanium alloy or Stainless Steel SURFIX® screws and lock screws available in two versions: cancellous bone screws diameter 6.5 mm and cortical bone screws diameter 4.5 mm. The SURFIX® system fixation creates a single implant/screw unit fixed into the bone thanks the lock screw.

Summary of Performance Studies
Dynamic tests determining fatigue strength indicate the good mechanical resistance of the SURFIX® Knee Osteotomy System.
Static tests determining bending strength in flexion and twisting of bone plates indicate the similar mechanical behavior of the SURFIX® Osteosynthesis System with a common plate.

§ 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)

The SURFIX® Knee Osteotomy System consists of seven different Stainless Steel plates with a locking system between the threaded sockets of the plates and the lock screws. There are six plates for the proximal tibia and one plate for the distal femur. Their fixation is provided by Titanium alloy or Stainless Steel SURFIX® screws and lock screws available in two versions: cancellous bone screws diameter 6.5 mm and cortical bone screws diameter 4.5 mm.

| INTENDED USE: | The SURFIX® Knee Osteotomy System is intended
for open and closed wedge osteotomies of the proximal
tibia and the distal femur, treatment of bone and joint
deformities, and malalignment caused by injury or
disease such as osteoarthritis. |
|-------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| INDICATIONS FOR
USE: | The SURFIX® Knee Osteotomy System is indicated
for knee osteotomies including high tibial osteotomy
and femoral osteotomy in the cases of osteoarthritis of
the medial tibiofemoral compartment with genu varum
and lateral gonarthrosis on genu valgum. Examples
include: |
| | - Fixation of opening wedge high tibial osteotomy,
- Fixation of fracture of the medial tibial plateau,
- Osteoarthritis of the medial tibiofemoral
compartment with genu varum, - Fixation of closing wedge high tibial osteotomy,
- Fixation of fracture of the lateral tibial plateau,
- Distal femoral varus osteotomy,
- Lateral gonarthrosis on genu valgum. |
| PREDICATE DEVICE: | The SURFIX® Knee Osteotomy System is
substantially equivalent to the Synthes TomoFix™
Osteotomy System (K023941) and the Arthrex
Modified Osteotomy System (K014155). |

PARISON OF OLOGICA ERISTICS:
The three systems are recommended for fixation of osteotomies, including high tibial osteotomy and femoral osteotomy.
For the Arthrex Modified Osteotomy System, plates and screws are made of Stainless Steel. For the Synthes TomoFix™ Osteotomy System, plates and screws are made of Titanium alloy. The SURFIX® Knee Osteotomy System provides plates made of Stainless Steel and, screws and lock screws made of Titanium alloy or Stainless Steel.
The three systems are fixed with screws.
UMMARY OF STODIES:
Dynamic tests determining fatigue strength indicate the good mechanical resistance of the SURFIX® Knee Osteotomy System.
Static tests determining bending strength in flexion and twisting of bone plates indicate the similar mechanical behavior of the SURFIX® Osteosynthesis System with a common plate.
