The provided text is a 510(k) Summary for the Arthrex Corkscrew FT II Suture Anchor. It primarily focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study with acceptance criteria and performance data in the typical sense of a diagnostic or AI device.
Therefore, many of the requested sections about acceptance criteria, study data, ground truth, and expert evaluation are not applicable to this type of regulatory submission for a medical device like a suture anchor. This document does not describe the performance of the device in a way that generates numeric metrics like sensitivity or specificity. Instead, the "performance" is implicitly demonstrated through substantial equivalence to a device already deemed safe and effective.
Here's an attempt to answer the questions based on the available information, noting where sections are not applicable:
Acceptance Criteria and Device Performance for Arthrex Corkscrew FT II Suture Anchor
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Material Equivalence: Materials of construction are effectively the same or have similar biocompatibility and mechanical properties as the predicate. | The device is a "fully threaded (FT) nondegradable screw," implying similar material properties to the predicate. No specific material acceptance criteria or test results (e.g., tensile strength, corrosion resistance) are explicitly stated in this summary, but these would have been part of the full 510(k) submission to demonstrate equivalence. |
| Design Equivalence: The functional design (e.g., screw type, method of suture attachment) is similar enough to the predicate. | The device is described as a "5.5 x 16mm fully threaded (FT) nondegradable screw" and "available configured with suture or with suture and needles," which implies a similar design and function to the predicate "Corkscrew Suture Anchor." Specific design parameters would have been compared in the full submission, but are not in this summary. |
| Intended Use Equivalence: The target anatomical locations and surgical indications are identical or highly similar to the predicate. | The intended uses listed (fixation of suture to bone in various anatomical regions like shoulder, foot/ankle, knee, hand/wrist, elbow, and pelvis for specific repairs) are directly compared and found to be "the same" as the predicate. |
| Performance Equivalence (Mechanical/Functional): The device performs its intended function (fixation of suture to bone) similarly to the predicate. This would typically involve mechanical testing (e.g., pull-out strength, fatigue). | The summary states, "Any differences between the Arthrex Corkscrew FT II Suture Anchor and the predicate Arthrex Corkscrew Suture Anchor are considered minor and do not raise questions concerning safety and effectiveness." This implies that any mechanical or functional performance tests conducted (which are not detailed in this summary) demonstrated comparable results to the predicate, satisfying the requirement for substantial equivalence. |
| Safety and Effectiveness Equivalence: The device is as safe and effective as the predicate. | "Based on the information submitted, Arthrex, Inc. has determined that the new Corkscrew FT II Suture Anchor is substantially equivalent to the currently marketed predicate device." This is the ultimate "performance" metric in a 510(k) summary, meaning it meets the FDA's threshold for safety and effectiveness compared to the predicate. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not Applicable. This document describes a medical device (suture anchor) for surgical implantation, not a diagnostic device or AI algorithm that would have a "test set" in the context of clinical or algorithmic performance evaluation (e.g., images for diagnostic accuracy). The data provenance for mechanical testing (if part of the full submission) would typically be from laboratory testing rather than patient 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)
- Not Applicable. As this is not a diagnostic or AI device, there is no "ground truth" to be established by experts in the sense of clinical interpretations or disease presence. The "ground truth" for a device like this is its physical and mechanical properties, and its safe and effective function in vivo, which is assessed through a combination of engineering tests, biocompatibility assessments, and clinical experience with similar predicate devices.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable. There is no "adjudication method" described as this is not a diagnostic study requiring consensus on interpretations.
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
- Not Applicable. This is a hardware medical device (suture anchor), not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable. This is a hardware medical device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- Not Applicable, in the typical sense of a diagnostic test. For a surgical implant like this, "ground truth" for safety and effectiveness is established through:
- Biocompatibility testing: Ensuring the materials are safe for implantation.
- Mechanical testing: Demonstrating adequate strength, fatigue resistance, and pull-out strength in a lab setting (e.g., using synthetic bone models or cadaveric tissue).
- Clinical experience with predicate devices: Relying on the established safety and effectiveness of the legally marketed predicate device.
- Literature review: Supporting the intended use and performance with existing medical knowledge.
The summary does not detail these specific "ground truths" but assumes they were addressed in the full 510(k) submission to support substantial equivalence.
8. The sample size for the training set
- Not Applicable. This is not an AI or machine learning device; therefore, there is no "training set."
9. How the ground truth for the training set was established
- Not Applicable. As there is no training set, this question is not relevant.
§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
