The provided text describes the 510(k) summary for the SIGNEX device, which comprises plates and screws for bone fixation. It details the substantial equivalence comparison to predicate and reference devices, along with performance data. However, it does not describe an AI/ML-based device. The information provided is purely for a mechanical medical device (bone fixation plates and screws). Therefore, I cannot extract information related to AI/ML acceptance criteria or a study proving an AI/ML device meets those criteria from this document.

The document discusses:

• Biocompatibility testing: Cytotoxicity, Sensitization, Irritation/Intracutaneous reactivity, Systemic toxicity, Genotoxicity, Pyrogen testing, Implantation testing, all conforming to ISO 10993 series.
• Mechanical testing: Torsion test (ASTM F543), Axial pullout strength test (ASTM F543), Driving torque test (ASTM F543), 4-Point bending test (ASTM F382).
• Clinical Studies: Explicitly states "No clinical data were necessary for the demonstration of substantial equivalence."

Since the request pertains to "acceptance criteria and the study that proves the device meets the acceptance criteria" specifically for an AI/ML device, and the provided text describes a mechanical bone fixation device, I am unable to fulfill the request as an AI/ML component is not present in the given information.

This document is a 510(k) Premarket Notification from the FDA for a medical device. It describes the device, its intended use, and its comparison to predicate devices, along with non-clinical performance data. However, it does NOT describe an AI/ML powered device, nor does it contain any information about a study proving device meets acceptance criteria related to AI/ML performance, such as human reader improvement with AI assistance, standalone algorithm performance, or the establishment of ground truth by multiple experts.

Therefore, I cannot provide the requested information. The document focuses on the substantial equivalence of a physical orthopedic implant system to existing predicate devices, based on mechanical, MRI compatibility, sterilization, shelf-life, and biological safety testing. It does not mention any AI or machine learning components.

The OsteoCentric Bone Plate and Screw is intended for fixation of fractures, and non-unions of the clavicle, scapula, olecranon, humerus, radius, ulna, pelvis, tibia, and fibula, including, but not limited to periarticular, and intraarticular fractures

The OsteoCentric Bone Plate and Screw System consists of implants and instruments designed for fixation to treat fractures, deformations, revisions and replantations of bones and bone fragments. The system features nineteen (19) types of plates and bone screws for fixation that are locking or non-locking, and a set of instruments to facilitate installation and removal of the implants. The plates have screw holes, which allow for attachment to the bones or bone fragments. The plates are fabricated from medical grade stainless steel (ASTM F138), and offered in various widths and lengths.

The provided text is a 510(k) summary for the OsteoCentric Bone Plate and Screw System. It details the device's characteristics, indications for use, and a comparison to predicate devices, but it does not contain information about an AI/ML-based medical device or any study proving a device meets acceptance criteria related to AI/ML performance.

Therefore, I cannot extract the information required to answer your questions regarding acceptance criteria, study details, sample sizes, expert involvement, or MRMC studies, as these concepts are not discussed in this document. The document describes a traditional medical device (bone plates and screws) and relies on substantial equivalence to previously cleared predicate devices, primarily through engineering analysis and existing performance testing of those predicates (ASTM F543 and ASTM F382).

The 510(k) clearance process for this type of device does not involve the kind of performance studies (e.g., clinical trials, AI algorithm validation) that would generate the data you're asking about.

The Flower Small and Medium Implants set is intended for use for internal fixation of fractures and reconstruction of bones, including the scapula, olecranon, humerus, radius, ulna, pelvis, distal tibia, fibula, hand and foot in adults and for use in long bones in adolescents (12-21) in whom the growth plates have fused. Examples of these internal fixations and reconstructions include compression fractures, intra-articular and extraaticular fractures, displaced fractures, osteotomies, non-unions and mal-unions.

This system can be used for palmar, ventral, dorsal or orthogonal application.

The Flower Small and Medium Implants set consists of the following components and accessories: pure titanium small straight plates, small and medium reconstruction plates, medium osteosynthesis plates, proximal humerus plates, distal radius plates, T-plates, angular T-shaped plates, H-shaped plates, mediocarpal plate; and titanium alloy screws. The device is also provided with general purpose instruments. All plates are made of pure titanium (ISO 5832-2).

The Flower Small and Medium Implants set provides fixed-angle lockable screws and plates to assist with internal fixation of fractures and reconstruction of bones. The principles of operation of the device are similar to other bone plating systems. The plates are comprised of various shapes. alignments, thicknesses, widths, and lengths designed to contour to different bones and locations on the body for internal fixation or reconstruction following fracture. .Each of the plates contains several locking holes that allow for the insertion of Flower Small and Medium Implants locking screws. To use the Flower Small and Medium Implants set, the surgeon first selects an implant of the appropriate size and shape based on the intended site of use. The plate should be placed in an appropriate location on the given bone or anatomical location in need of repair.

The provided text describes a 510(k) premarket notification for the "Flower Small and Medium Implants" a bone plating system. It details the device's intended use, technological characteristics, and compares it to predicate devices to establish substantial equivalence.

However, the document does not contain information related to acceptance criteria, diagnostic performance metrics (like sensitivity, specificity, AUC), or a study design to measure these. The "Performance Data" section lists only:

• Biocompatibility testing (ISO 10993-1, ISO 10993-5)
• Sterilization validation
• Packaging validation and shelf life testing

These are general safety and manufacturing aspects, not data on the clinical or diagnostic performance of the device in the context of typical AI/software-as-medical-device studies. The device is a physical orthopedic implant, not an AI or software device that would have metrics like sensitivity or specificity.

Therefore, I cannot provide a table of acceptance criteria and reported device performance or information regarding sample sizes, ground truth establishment, expert adjudication, or MRMC studies for diagnostic accuracy, as this information is not present in the provided 510(k) summary.

The summary states: "Engineering analysis has been performed to demonstrate that the Flower Small and Medium Implants system provides appropriate mechanical strength for its intended use." This suggests mechanical testing was done, but the specific acceptance criteria and results for this are not detailed beyond a general statement of "functional as intended."
