The SternalPlate System is indicated for use in stabilization and fixation of fractures of the anterior chest wall including sternal fixation following sternotomy, sternal fracture(s), and sternal reconstructive surgical procedures to promote bony fusion.
This Special 510(k) is submitted to evaluate the modifications to the Predicate Device plates resulting in the Subject Device plates. There have been no changes to the previously cleared plates and screws cleared in K183172, this submission is only for the addition of the four new Subject Device plates. The four Subject Device plates include T-Plates and Transverse Plates. Both Subject Device variants, the T-Plates and Transverse Plates, are geometrically derived from the following Predicate Device plates: the Ladder Plate Narrow (Reff/ 4740006) and the Straight 24-hole Plate (Ref# 4740012). The Subject Device plates therefore have the same features, the same tolerances, and are made from the same material as the Predicate Device plates. Furthermore, the Subject Device plates are manufactured with the same manufacturing process as the Predicate Device plates.
The provided FDA 510(k) summary (K243491) for the Stryker SternalPlate Expansion device focuses on the mechanical performance of the device and its biocompatibility. The document does not contain information related to software, AI, or human-in-the-loop performance. Therefore, many of the requested criteria cannot be extracted from this document.
Here's the information that can be extracted or deduced from the provided text:
1. A table of acceptance criteria and the reported device performance
The document states that the "Subject Device plates met all acceptance criteria as compared to the Additional Predicate Devices." However, the specific quantitative acceptance criteria (e.g., minimum stiffness, maximum deflection) and the detailed reported performance values are not explicitly stated in the provided 510(k) summary. The summary only mentions "appropriate strength and stiffness."
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document refers to "Performance Bench Testing" but does not specify the sample size for the mechanical tests. The tests compare the Subject Device to "Additional Predicate Devices," implying a comparative mechanical study rather than a clinical data-driven study. Data provenance (country of origin, retrospective/prospective) is not applicable as it's a bench test, not clinical data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This question is not applicable as the document describes mechanical bench testing of an orthopedic implant, not a diagnostic device requiring expert interpretation of images or data to establish a ground truth.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This question is not applicable as the document describes mechanical bench testing. Adjudication methods are typically relevant for clinical studies or studies involving human readers/interpreters.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
There is no mention of a multi-reader multi-case (MRMC) comparative effectiveness study. This document is for a physical orthopedic implant, not an AI-powered diagnostic tool. Therefore, the effect size of human readers with/without AI assistance is not relevant to this submission.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This question is not applicable as the device is a physical orthopedic implant, not a standalone algorithm or software.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the performance bench testing, the "ground truth" would be the engineering specifications and established mechanical testing standards against which the device's strength and stiffness are evaluated. The document states "The Subject Device plates met all acceptance criteria as compared to the Additional Predicate Devices," implying a comparison against established performance benchmarks of legally marketed devices.
8. The sample size for the training set
This question is not applicable as the device is a physical orthopedic implant. There is no concept of a "training set" in the context of mechanical bench testing for this type of device.
9. How the ground truth for the training set was established
This question is not applicable for the reasons stated above.

|---|---|---|
| IntendedUse/Indications forUse | The SternalPlate System is indicated for use in stabilizationand fixation of fractures of the anterior chest wall includingsternal fixation following sternotomy, sternal fracture(s), andsternal reconstructive surgical procedures to promote bonyfusion. | The SternalPlate System is indicated for use in stabilization andfixation of fractures of the anterior chest wall including sternalfixation following sternotomy, sternal fracture(s), and sternalreconstructive surgical procedures to promote bony fusion. |
Please note that this 510(k) lists several additional Predicate devices, however, these additional Predicate devices were used for testing and not verall substantial equivalence evaluation.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE [§807.92(a)(6)]
The Subject Device is compared to its Predicate Devices for substantial equivalence of technological characteristics based on the following criteria:
- A. Principles of Operation
- B. Technological Characteristics
A. Principles of Operation / Operating Principle
The basic operating principle of the Subject Device remains the same as the Predicate Device. The basic operating principle of the Subject Device, as well as the Predicate Device is fixation and stabilization of the anterior chest wall. The method of site preparation and fixation is the same for both the Subject and Predicate Device. The fundamental scientific technology of the Subject Device has not changed. This is because the principle of operation, the mechanism of action, the intended use, and the materials of construction have not changed as a result of the device modifications.
B. Technological Characteristics
There have been no changes to the previously cleared plates and screws cleared in K183172, this Special 510(k) is only for the addition of the four new Subject Device plates. The four Subject Device plates include T-Plates and Transverse Plates. Both Subject Device variants, the T-Plates and Transverse Plates, are geometrically derived from the following Predicate Device plates: the Ladder Plate Narrow (Reff/ 4740006) and the Straight 24-hole Plate (Ref# 4740012).
The Subject Device plates therefore have the same features, the same tolerances, and are made from the same material as the Predicate Device plates. Furthermore, the Subject
{7}------------------------------------------------
Device plates are manufactured with the same manufacturing process as the Predicate Device plates.
VI. PERFORMANCE DATA [§807.92(b)(7)]
Appropriate strength and stiffness of the new plates are confirmed by the Verification and Validation testing, and no new questions of safety or effectiveness arise as a result of the testing.
The subject devices have been evaluated for Biocompatibility per the requirements of ISO 10993-1:2018 and in alignment with corresponding FDA guidance. This evaluation has concluded that no new or increased biocompatibility risks are associated with the subject device.
Sterility testing was not required as a basis for substantial equivalence. There is no change in the subject device material, manufacturing process, duration or location of contact, or reprocessing methods.
Performance Bench Testing
As the Subject Device plates, unlike the original Predicate Device plates, can be fixated laterally to the sternum, additional Verification and Validation data was needed for the Subject Device. This submission uses well established test methods used in prior submissions including K183172 previously reviewed by the FDA. These tests are summarized within the Special 510(k).
Plate stiffness and strength were tested in comparison to the Additional Predicate Devices DePuy Synthes Sternal Fixation System (K190963) and KLS Martin Thoracic Plating System (K153482). The Subject Device plates met all acceptance criteria as compared to the Additional Predicate Devices. The results of this testing show that the Subject Device plates do not raise new questions in terms of safety and effectiveness when compared to the Predicate Device plates.
Animal Testing
Animal testing was not required as a basis for substantial equivalence.
Clinical Testing [§807.92(b)(2)]
Clinical testing was not required as a basis for substantial equivalence.
VII. CONCLUSIONS [§807.92(b)(3)]
In summary, the Subject Device is substantially equivalent to its Predicate Device. The Subject Device's features, tolerances, material, mechanism of action, intended use, and
{8}------------------------------------------------
manufacturing process are the same as the Predicate Device. The Subject Device's intended use is unchanged compared to the Predicate Device. Appropriate strength and stiffness of the new plates are confirmed by the Verification and Validation testing, and no new questions of safety or effectiveness arise as a result of the testing. There are no new questions of safety or effectiveness regarding the modifications to the Predicate Device plates resulting in the four Subject Device plates. According to the comparison based on the requirements of 21 CFR 807.87 and the information provided herein, it is concluded that the information included in this submission supports substantial equivalence to the predicate devices.
§ 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.
