No
The device description and performance studies focus on mechanical components and their physical properties, with no mention of AI or ML technologies.
No
The device is described as an internal fixation system for fractures and reconstruction, and an accessory (aiming blocks) for screw placement. These are structural components used during surgery, not devices that deliver therapy.
No
The device is an orthopedic implant and surgical accessory used for internal fixation of fractures, not for diagnosing medical conditions.
No
The device description clearly states that the device is an accessory (aiming blocks) made of physical materials (PEEK and stainless steel) used intra-operatively to guide screw placement. It also mentions benchtop testing of the physical components. This indicates a hardware device, not a software-only device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The provided text describes a system of plates and aiming blocks used for the internal fixation of bone fractures, specifically in the distal radius. These are surgical implants and instruments used directly on the patient's body during a procedure.
- Intended Use: The intended use is for "internal fixation for fractures and reconstruction of the small bones." This is a surgical procedure, not a diagnostic test performed on a sample outside the body.
The device is clearly a surgical device used for treatment, not a diagnostic device used for testing samples.

Intended Use / Indications for Use
The VariAx® Distal Radius Locked Plating System Line Extension addition of Aiming Blocks does not alter the intended use of the predicate system as cleared in K040022 and K 100271. The indications for use for the subject plates are provided below.
The VariAx® Distal Radius Plates are intended for use for internal fixation for fractures and reconstruction of the small bones, primarily including the distal radius. Examples of these internal fixations and reconstructions include compression fractures, intra-articular and extra-articular fractures, displaced fractures, osteotomies, non-unions and mal-unions. This system can be used for palmar, dorsal or orthogonal application.

Device Description
This Special 510(k) submission is intended to add aiming blocks as an accessory to the VariAx® Distal Radius plate line which was cleared in K040022 and K100271. The aiming blocks are accessories used intra-operatively to guide the user in placement of the screws into the plate. There are 4 aiming blocks which correspond to the configurations of volar plates: Narrow Right, Narrow Left, Standard Right and Standard Left. The aiming blocks are used with a joystick tool which helps the user find the appropriate screw trajectory and is pinned in place once the desired alignment is obtained. Kirschner wires can also be used in conjunction with the aiming blocks to determine screw trajectory.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Benchtop testing was conducted to demonstrate that the use of the aiming blocks as described in the operative technique could withstand clinically relevant loads. Torque to failure was performed using the joystick and the block assembled and failure loads were found to be acceptable. Lateral loads were also placed on the construct and the failure mode was disassembly without significant damage to the plate. Biocompatibility testing of the materials in the aiming block assembly (PEEK and stainless steel) was conducted as well as cleanability testing, sterility testing and corrosion resistance testing.
Clinical testing was not required for this submission.

§ 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)

Examples of these internal fixations and reconstructions include compression fractures, intra-articular and extra-articular fractures, displaced fractures, osteotomies, non-unions and malunions. This system can be used for palmar, dorsal or orthogonal application.
Summary of Technologies:
The proposed device is substantially equivalent in intended use, materials and performance characteristics to the predicate device. Addition of the aiming block as an accessory to the bone plating system does not alter the technology.
Non-Clinical Testing:
Benchtop testing was conducted to demonstrate that the use of the aiming blocks as described in the operative technique could withstand clinically relevant loads. Torque to failure was performed using the joystick and the block assembled and failure loads were found to be acceptable. Lateral loads were also placed on the construct and the failure mode was disassembly without significant damage to the plate. Biocompatibility testing of the materials in the aiming block assembly (PEEK and stainless steel) was conducted as well as cleanability testing, sterility testing and corrosion resistance testing.
Clinical Testing:
Clinical testing was not required for this submission.
Conclusion:
The VariAx® Distal Radius Locked Plating System Line Extension addition of Aiming Blocks are substantially equivalent to the predicate devices identified in this premarket notification.
