The StaXx™ FX System is indicated for use in the reduction of spinal fractures. It is intended to be used in combination with Stryker Spineplex™ Radiopaque Bone Cement.
The StaXx™ FX System is a vertebral fracture reduction device composed of a base wafer and stackable wafers fabricated from preformed Polyetheretherketone (PEEK-OPTIMA) with 6% Barium Sulfate (BaSO4). The wafers are designed to be inserted incrementally into the vertebral body to form a column that provides the desired fracture reduction. Twenty (20) wafers are provided per package. The wafers are provided in one width (8mm) with three lengths (20mm, 25mm, 30mm).
The provided text describes a 510(k) submission for the "StaXx™ FX System," a device intended for reducing spinal fractures. The submission establishes substantial equivalence to a predicate device through mechanical testing. However, the document does not contain specific acceptance criteria, reported device performance data, details of a study demonstrating fulfillment of acceptance criteria, or most of the requested information about sample sizes, ground truth, or expert involvement.
The key statement regarding performance is: "In addition, mechanical testing demonstrated that the StaXx™ FX System meets the performance requirements for its intended use." This is a high-level summary and lacks the detailed information requested.
Therefore, most of the requested information cannot be extracted from the provided text.
Here's what can be inferred or directly stated from the document:
- Table of acceptance criteria and the reported device performance:
- The document only states that "mechanical testing demonstrated that the StaXx™ FX System meets the performance requirements for its intended use." No specific acceptance criteria (e.g., strength, durability thresholds) or detailed performance metrics (e.g., maximum load, fatigue life) are provided.
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Not specified | Met "performance requirements for its intended use" through mechanical testing. |
-
Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective): Not specified. The document only mentions "mechanical testing."
-
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): Not applicable, as this was mechanical testing, not a clinical study involving human interpretation of data where "ground truth" would be established by experts in that context.
-
Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable (mechanical testing).
-
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: Not applicable. This device is a mechanical implant, not an AI or imaging diagnostic tool.
-
If a standalone (i.e., algorithm only without human-in-the loop performance) was done: Not applicable. This device is a mechanical implant.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable in the context of clinical expert-derived ground truth. For mechanical testing, the "ground truth" would be the engineering specifications and material properties against which the device's mechanical performance is measured.
-
The sample size for the training set: Not applicable. This is mechanical testing, not a machine learning model.
-
How the ground truth for the training set was established: Not applicable. This is mechanical testing.

Substantial equivalence1
The StaXx™ FX System described in this submission is substantially equivalent to the following device:
| Predicate Device | Manufacturer | 510(k) No. |
|---|---|---|
| StaXx™ FX System | Spine Wave, Inc. | K053336 |
In addition, mechanical testing demonstrated that the StaXx™ FX System meets the performance requirements for its intended use. The minor differences between the StaXx™ FX System and the predicate device do not raise any new questions of safety or effectiveness. Thus, the StaXxTM FX System is substantially equivalent to its predicate device.
Use of the terms "substantially equivalent" and "substantial equivalence" in this application is intended only to denote a comparison of the subject device to predicate devices for the purpose of an FDA review of the safety and effectiveness of the subject device in accordance with 21 CFR 807. Statements comparing the subject device to predicate devices, including statements regarding "substantial equivalence", contained in any way to relate to patentability, patent infringement, or any analysis of the subject device under foreign or United States patent laws including 35 U.S.C. paragraph 100 et seg. or related judicial doctrines

Dear Mr. Smith:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
