The summary describes a system of titanium plates for orthopedic fixation and does not mention any software, algorithms, or AI/ML capabilities. The performance studies focus on mechanical testing of the plates.
Yes
The device is described as "fixation of fractures" and "treatment of bone and joint deformities," which aligns with the definition of a therapeutic device designed to treat or alleviate a medical condition.
No
The device is described as an osteotomy system consisting of titanium plates for stable fixation of osteotomies and fractures, indicating a therapeutic or surgical purpose rather than a diagnostic one.
No
The device description explicitly states that the system consists of "five different titanium plate families" and describes "plates designed to provide stable fixation of osteotomies." This indicates the device is a physical implant, not software. The performance studies also focus on mechanical testing of these physical plates.
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 surgical procedures involving bone and joint deformities, fractures, and malalignment. This is a therapeutic and structural purpose, not a diagnostic one.
- Device Description: The device is described as a system of titanium plates and screws designed for stable fixation of bones. This is consistent with a surgical implant, not a diagnostic test.
- Lack of Diagnostic Elements: There is no mention of the device being used to analyze samples (blood, tissue, etc.), detect biomarkers, or provide information for diagnosis.
- Performance Studies: The performance studies described are mechanical tests (axial, torsion, bending, fatigue) on the plates and screws, which are relevant to the structural integrity and function of a surgical implant. There are no studies related to diagnostic accuracy or performance.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Static and dynamic construct testing was completed for the plates included in the DePuy Synthes TOMOFIX Osteotomy System in order to demonstrate comparable mechanical performance to the predicates. The mechanical testing was designed to assess the stiffness and fatigue strength of the subject devices. The following tests and analyses were performed:
- Axial Testing conducted by mounting the plates on an osteotomized sawbone femur model and subjecting the plates to an axial load
- Torsion Testing - conducted by mounting the plates on an osteotomized sawbone femur model and subjecting the plates to a torsional load
- Bending Stiffness - ProEngineer CAD software was used to calculate and compare stiffness properties in the critical cross section of the plates
- Dynamic (Fatigue) Testing – conducted by mounting the plate-screw constructs on POM-C test blocks with a milled surface to match the bottom of the plate and introducing a cyclical axial force
The results of the mechanical testing and engineering analyses demonstrate substantial equivalence.

§ 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)

Substantial The intent of this submission is to update the indications for use Equivalence: statement of the DePuy Synthes TOMOFIX Osteotomy System (cleared under K023941) by specifying osteotomy type (open or closed) and specific anatomical region indicated for each plate family in the system. Information has been provided to support the use of the DePuy Synthes TOMOFIX Osteotomy System for the proposed indications to support a substantially equivalent decision in comparison to the predicate Synthes TOMOFIX Osteotomy System as cleared under K023941.
It is also the intent of this submission to modify the design of the DePuy Synthes TOMOFIX Medial Distal Femur Plate. Information presented supports substantial equivalence of the DePuy Synthes TOMOFIX Medial Distal Femur Plate to the predicate devices, Synthes TOMOFIX Medial Distal Femur Plates (K081353), Synthes TOMOFIX Osteotomy System (K023941) and Synthes Large Fragment Dynamic Compression Locking System (K000682). The proposed plates have similar indications for use, design characteristics, materials, and incorporate the same fundamental technology.
Performance Data
Static and dynamic construct testing was completed for the plates included in the DePuy Synthes TOMOFIX Osteotomy System in order to demonstrate comparable mechanical performance to the predicates. The mechanical testing was designed to assess the stiffness and fatigue strength of the subject devices. The following tests and analyses were performed:
- Axial Testing conducted by mounting the plates on an ● osteotomized sawbone femur model and subjecting the plates to an axial load
- Torsion Testing - conducted by mounting the plates on an osteotomized sawbone femur model and subjecting the plates to a torsional load
- Bending Stiffness - ProEngineer CAD software was used to calculate and compare stiffness properties in the critical cross section of the plates
