Biomet Microfixation Twist Drills are intended for drilling holes in large and small bone during orthopedic, spinal, neurosurgical, medial sternotomy, and oral and maxillofacial procedures.

Biomet Microfixation manufactures and distributes a variety of single use twist drills to aid in the implantation of Biomet Microfixation implants. Biomet Microfixation Twist Drills are intended for drilling holes in large and small bone during orthopedic, spinal, neurosurgical, medial sternotomy, and oral and maxillofacial procedures. The drills are manufactured from Stainless Steel. Some drills contain flutes along the majority of the drill length, while others contain a "stop" feature which prevents further drilling past a designated length. Additionally, some drills contain an "adjustable stop" feature which allows to surgeon to set the stop length intraoperatively. Twist Drills are distributed non-sterile and are intended for single-patient use. Cleaning should only be performed on new or uncompromised drills. The drills should be steam sterilized by the health-care facility prior to use.

This FDA 510(k) summary is for a medical device (Twist Drills), not an AI/ML algorithm. Therefore, many of the requested categories related to algorithm performance, training data, and expert review are not applicable.

Here's an analysis of the provided document based on the available information:

This document describes the FDA's decision to clear the Biomet Microfixation Twist Drills (K213208) as substantially equivalent to a predicate device (Twist Drills K062842).

1. A table of acceptance criteria and the reported device performance

The document states that "Design verification and validation testing were performed on the subject devices" and "The results from all design verification and validation tests confirmed that the subject devices met the predetermined acceptance criteria." However, the specific, quantitative acceptance criteria themselves are not provided in this summary document. The performance is reported as meeting these unspecified criteria.

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

This document discusses performance testing for a physical medical device, not a data-driven AI/ML algorithm. Therefore, terms like "test set" and "data provenance" in the context of data analysis are not directly applicable. The document refers to "design verification and validation testing," which would involve physical samples of the drill. The sample size for these physical tests is not specified in this summary.

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)

This is not applicable as the document describes a physical medical device, not an AI/ML diagnostic or prognostic tool that requires expert-established ground truth.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

This is not applicable for a physical medical device without a diagnostic component.

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

This is not applicable as the document describes a physical medical device, not an AI-assisted diagnostic tool.

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

This is not applicable as the document describes a physical medical device.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

For a physical medical device like a drill, "ground truth" generally refers to objective physical and mechanical properties. The validation would typically involve comparing the device's performance against predefined engineering specifications and safety standards, rather than expert consensus on diagnostic images or pathology. The document generally refers to "predetermined acceptance criteria" and "design verification and validation tests."

8. The sample size for the training set

This is not applicable as the document describes a physical medical device, not an AI/ML algorithm that requires a training set.

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

This is not applicable as the document describes a physical medical device.

The Stryker® Twist Drills are intended to be used for drilling holes in large and small bone during orthopedic, spinal, neurosurgical, medial sternotomy, and oral and maxillofacial procedures.

Not Found

This document primarily concerns the 510(k) summary and FDA clearance letter for the Stryker® Twist Drills. It focuses on establishing substantial equivalence to predicate devices and detailing the intended use and regulatory classification.

Based on the provided text, there is no information available regarding acceptance criteria or a study proving device performance in the context of an AI/algorithm-driven device. The Stryker® Twist Drills are a physical medical device (drills), not an AI or software-based system that would typically have the acceptance criteria and study details you've outlined.

Therefore, I cannot provide the requested information for the following points as they are not applicable to the provided document:

1. A table of acceptance criteria and the reported device performance
2. Sample size used for the test set and the data provenance
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
4. Adjudication method for the test set
5. If a multi-reader, multi-case (MRMC) comparative effectiveness study was done
6. If a standalone (i.e. algorithm only, without human-in-the-loop performance) was done
7. The type of ground truth used
8. The sample size for the training set
9. How the ground truth for the training set was established

The document focuses on regulatory clearance for a physical medical tool, asserting its substantial equivalence to existing drills based on design and intended use, rather than demonstrating algorithm performance.
