The provided document is a 510(k) Premarket Notification for the "NET Brand Small Fragment and Large Fragment Osteosynthesis Plating System, NET Brand of DHS/DCS Plating System." This document aims to demonstrate substantial equivalence to legally marketed predicate devices, not to establish new performance criteria through a standalone study with acceptance criteria.

Therefore, the document does not contain the requested information about acceptance criteria and a study proving the device meets those criteria, as it is not a performance study in that sense.

Instead, the document focuses on demonstrating substantial equivalence to predicate devices. This is achieved by comparing the new device's technological characteristics, intended use, materials, and performance (via testing against established ASTM standards) to those of already approved predicate devices.

Here's an explanation based on the provided text, addressing the points where information is available or noting its absence:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not define specific "acceptance criteria" for clinical performance in terms of sensitivity, specificity, accuracy, or similar metrics for a new diagnostic or prognostic device. Instead, it demonstrates compliance with recognized engineering and material standards to show that the device performs equivalently to previously approved devices.

The "reported device performance" is essentially a confirmation of conformance to established ASTM standards for bone plates and screws.

2. Sample size used for the test set and the data provenance:

• Sample Size: The document does not specify a "sample size" in terms of patient cases or images, as it is a mechanical device submission. The testing involves mechanical specimens (e.g., plates and screws) tested according to the cited ASTM standards. The specific number of specimens tested for each standard is not detailed in this summary.
• Data Provenance: Not applicable as it's not a clinical or imaging study. The tests are mechanical and presumably conducted in a laboratory setting.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

Not applicable. This is a submission for a bone fixation device, not a diagnostic device requiring expert interpretation for ground truth establishment. Mechanical testing relies on standardized methodologies, not expert consensus on clinical cases.

4. Adjudication method for the test set:

Not applicable for a mechanical device submission.

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 medical device for bone fixation, not an AI or diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:

Not applicable. This is a medical device for bone fixation, not an algorithm.

7. The type of ground truth used:

The "ground truth" in this context is the established performance benchmarks defined by recognized industry standards (ASTM F382, ASTM F384, ASTM F543 for performance, and ASTM F136, ASTM F138, ASTM F139 for materials). The device is deemed acceptable if it conforms to these standards, indicating mechanical properties are comparable to legally marketed devices.

8. The sample size for the training set:

Not applicable. This is a mechanical device, not a machine learning model requiring a training set.

9. How the ground truth for the training set was established:

Not applicable, as there is no training set for this type of device submission. The "ground truth" for demonstrating substantial equivalence rests on adherence to material and performance standards, which are developed and accepted by the scientific and engineering community.

Ask a specific question about this device

The I.T.S. Fibula Plate PROlock with Angular Stability is a titanium implant fracture fixation system for repairing bone fractures located from the middle to the distal third of the fibula.

Indications for Use include metaphysial and diaphysial fracture fixation of acute fractures, malunions, and non-unions of the distal fibula. Other indications include corrective osteotomy and open and closed fractures.

The system is not intended for spinal use.

The I.T.S. Fibula Plate PROlock with Angular Stability is a low-profile left and right titanium plate in three lengths with various length cortical and/or cancellous locking self-tapping stabilization screws. The fibula plate is made from CP Titanium according to ASTM F 67-00 and the screws are made from 6-4 Alloyed Titanium according to ASTM F 136-02. The plate and screws are surface conditioned with a TIODIZE, Type II preparation.

The provided text describes a medical device, the I.T.S. Fibula Plate PROlock with Angular Stability, and its 510(k) summary for clearance by the FDA. However, it does not contain information about acceptance criteria or a study proving that the device meets those criteria.

The 510(k) summary focuses on establishing substantial equivalence to predicate devices, not on demonstrating specific performance metrics against defined acceptance criteria through a clinical study.

Therefore, I cannot provide the requested information about acceptance criteria, device performance, sample sizes, ground truth, or an MRMC study based on the provided text.

Here's why and what information is present:

• Acceptance Criteria and Reported Device Performance: This information is completely absent. The document is about regulatory clearance based on substantial equivalence, not performance testing.
• Study Details (Sample Size, Data Provenance, Experts, Adjudication, MRMC, Standalone, Ground Truth, Training Set): None of this is mentioned. The clearance is based on the device's design, materials, and intended use being similar to already marketed devices. The document does not describe a clinical study in the way you've outlined.
