SPS Small Fragment Set The Stryker® Plating System, Small Frag Set is indicated for fractures of the metaphysis and/or the diaphysis of the following:

One third tubular plate: fibula, metatarsals, metacarpals
Fibular plate: fibula
Compression plate: radius, ulna, distal tibia, fibula, distal humerus, clavicle
Oblique T-plate: distal radius
T-plate: distal radius, calcaneus, lateral clavicle
Cloverleaf plate: proximal humerus, distal tibia
Calcaneal plate: calcaneus
Reconstructive plate: humerus, pelvis Screws are used either to fasten plates or similar devices onto bone, or, as lag screws, to hold together fragments of bone.

SPS Basic Fragment Set The Basic Fragment Set is intended for use in long bone fracture fixation. Reconstruction plates, wide and narrow straight and waisted compression plates are indicated for fixation of long bone fractures including but not limited: to fractures of the femur, the tibia, the humerus and the pelvis. T-plates, Tbuttress plates and L-buttress plates are indicated for fractures at the proximal or distal end of long bones including but not limited to: fractures of the femoral condyles, the tibial plateau, the distal tibia and the proximal humerus.

Device Description

The AxSOS 3 Ti system includes anatomically contoured monoaxial locking plates, as well as screws and blind screws. The plates have been designed with holes that can accommodate either locking or non-locking screws, and also include holes for suture and Kirshner wires (K-wires). The screws come in 3 types (locking, cortical, and cancellous) and are available in several different diameters. All implantable components come sterile and non-sterile.

The Basic Fragment Set is part of the Stryker Plating System. The Basic Fragment Set consists of plates and screws for fixation of fractures of the cortical and metaphyseal area of the long bone as well as fracture of the pelvis. The implant set is available in either in stainless steel (316 L) or titanium alloy (Ti6Al4V).

This submission is not intended to introduce any new implants into the system, but rather to demonstrate compatibility between the AxSOS 3 Ti system (K153379) and several of the titanium screw/plate components found in the Stryker Plating System (SPS) most recently cleared in K060798. The AxSOS 3 Ti plates and screws are manufactured from titanium alloy (Ti6Al4V) per ASTM F136 and available sterile and non-sterile.

AI/ML Overview

This document is a 510(k) premarket notification for a medical device called the "AxSOS 3 Ti; Stryker Plating System." As such, the purpose of this submission is to demonstrate substantial equivalence to legally marketed predicate devices, not to establish new performance criteria or conduct clinical trials in the way a PMA (Premarket Approval) submission would.

Therefore, the provided document does not contain the information requested regarding acceptance criteria, device performance, sample sizes for test and training sets, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance.

Instead, the document focuses on:

Indications for Use: Detailing what the device is intended for (e.g., long bone fracture fixation, specific types of fractures, different anatomical locations).
Device Description: Explaining the components (plates, screws), materials (titanium alloy), and forms (sterile/non-sterile).
Predicate Devices: Identifying previously cleared devices to which the current device is compared for substantial equivalence.
Non-Clinical Testing: Mentioning "Bench testing and an engineering analysis" to demonstrate compatibility between components, and bacterial endotoxin testing for pyrogenicity.
Absence of Clinical Testing: Explicitly stating that "Clinical testing was not required for this submission."

The "Conclusion" section reinforces that the submission is about demonstrating cross-compatibility between two existing systems (AxSOS 3 Ti and Stryker Plating System) based on bench testing and engineering analysis, rather than proving performance against specific acceptance criteria through extensive studies as typically understood in the context of AI/software device evaluation.

Dear Irene Bacalocostantis:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

Summary of Technologies

There are no changes to the design or technological characteristics of the AxSOS 3 Ti system implants, nor in the Stryker Plating System.

Non-Clinical Testing

Bench testing and an engineering analysis were provided to demonstrate compatibility between components.

Bacterial endotoxin testing (BET) as specified in ANSI/AAMI ST72:2011 was used for pyrogenicity testing to achieve an Endotoxin limit of ‹ 20EU/Device.

Clinical Testing

Clinical testing was not required for this submission.

Conclusion

There have not been any changes or component additions to the AxSOS 3 Ti system. A bench testing and engineering analysis show that several of the plate and screw components in the AxSOS 3 Ti and Stryker Plating System are cross-compatible. The cross-compatibility between the AxSOS 3 Ti System and Stryker Plating System are found in the operative technique guides.

Regulation Number and Section

§ 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.
