The summary describes a system of mechanical tools and plates for surgical procedures, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes
The device is used for fixation following osteotomies, which is a therapeutic intervention to correct deformities or injuries.
No
Explanation: The device is described as a system for fixation following osteotomies, including tools for opening a wedge and bone plates for maintaining that opening. Its intended use is therapeutic (providing fixation), not for diagnosing medical conditions.
No
The device description explicitly lists hardware components such as a guide system, osteotomes, a forked-wedge tool, and bone plates.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Intended Use: The Arthrex Opening Wedge Osteotomy System is intended for use in surgical procedures to fix bones after osteotomies (bone cuts). It is a surgical instrument and implant system used directly on the patient's bone.
- Device Description: The components described (guide system, osteotomes, forked-wedge tool, bone plates) are all surgical tools and implants, not diagnostic reagents or equipment used to analyze biological samples.
Therefore, the function and application of this device fall under the category of surgical devices, not in vitro diagnostics.

§ 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)

Arthrex Opening Wedge Osteotomy System Trade Name: Common Name: Bone Plate and Accessories Plate, Fixation, Bone (per 21 CFR 888.3030) Classification:
Description:
There are two schools of thought regarding osteotomy methods: the closing wedge method, and the opening wedge method, in the closing wedge method, removal of a bone wedge creates an angled gap in the bone. Part of the bone is left as a hinge at the apex of the angle. The hinge allows the gap to narrow and the bone material on either side of the closed gap joins together.
In the opening wedge method, a cut is made across the bone. Part of the bone is left as a hinge, as in the closing wedge method. In contrast to the closing wedge method, however, the hinge allows the cut gap to open. The open wedge is filled with graft material.
The two methods are performed on opposite sides of the bone to give equivalent results. For example, when a given deformity would be corrected by performing the opening-wedge procedure on the medial side of a bone, an equivalent closing-wedge correction would be performed laterally.
The closing wedge method is the current standard, although several disadvantages are associated with the technique. The most significant disadvantages of the closing wedge method are: (i) disruption of the tibial-femoral joint; (ii) possible damage to neurovascular structures; and, (iii) disruption of the medial cortex, resulting in instability and nonunion between the upper and lower bone because of possible soft tissue interference. It is also difficult to compute the correct amount of bone to remove, and, therefore, several extra cuts may be required.
The opening wedge technique avoids or limits many of the disadvantages associated with the closing wedge-method. Additionally, the medial, open-wedge HTO has the following advantages over the closed, lateral-wedge HTO: (i) simplicity; (iii) ability to quickly change angle at any time during the procedure; and (iv) no fibular osteotomy is required. Nevertheless, only a few surgeons are currently using the opening wedge procedure. This is most likely due to a lack of functional, easy to use instrumentation.
1
The Arthrex Opening Wedge Osteotomy System overcomes the disadvantages of the prior art and fulfills the above-described need by providing a bone plate system for performing the opening wedge osteotomy technique. The bone plate system of the present invention includes the following basic components: a guide system, osteotomes, a forked-wedge tool for opening the wedge, and a set of bone plates for maintaining the wedge opening.
The osteotomy plates are made of surgical grade stainless steel, the biocompatibility of which has been well documented.
Intended Use:
The Arthrex Opening Wedge Osteotomy System are intended to be used in conjunction with bone screws to provide fixation following Proximal Tibial or Distal Femoral opening wedge osteotomies.
Substantial Equivalence:
By definition, substantial equivalence means that a device has the same intended use and the same technological characteristics as the predicate device, or has the same intended use and different technological characteristics, but it can be demonstrated that the device is as safe and effective as the predicate device and does not raise different questions regarding safety and effectiveness from the predicate device.
The primary differences between the Arthrex and Intermedics bone plates are as follows:
| Intermedics | Arthrex | |
|---|---|---|
| Configuration | "L" shaped plates | "T" shaped and "I" shaped plates |
| Metal Spacer | No | Yes |
| Material | Titanium Alloy | Surgical Grade Stainless Steel |
The configuration of any bone plate should ideally provide both axial and torsional stability. Since each of these designs provides fixation in more than one plane, such stability is guaranteed. The Intermedics technique calls out for the opening resulting from an opening wedge osteotomy to be filled with a combination of cancellous bone and wedges of bone from the Iliac Crest. The Arthrex technique also calls out for the use of wedges of bone; however, the Arthrex plate also has a metal spacer to provide further support. Although the material for the two plates differs, both have proven track records as acceptable implant materials. Surgical Grade Stainless Steel has been and still is commonly used in a number of fixation devices. None of the -aforementioned differences make the Arthrex plates any less safe and effective than the Intermedics plates. Furthermore, they do not raise any different questions regarding safety and effectiveness from the predicate device.
