Intended Use

The Avanti Orthopaedics 2.2mm Cannulated Compression Screws are intended for fixation of fractures, fusions, osteotomies, non-unions of small bones in adults and in both children (2-12 years) and adolescents (12-21 years) in which growth plates have fused or in which growth plates will not be crossed by screw fixation.

The Avanti Orthopaedics 3.2mm, and 4.0mm Cannulated Compression Screws are intended for fixatures, fusions, osteotomies, non-unions of small bones and small bone fragments in adults and in both children (2-12 years) and adolescents (12-21 years) in which growth plates have fused or in which growth plates will not be crossed by screw fixation.

Device Description

The Avanti Orthopaedics Cannulated Compression Screw System are metallic bone screws manufactured from Stainless Steel (ASTM F138). The screws are available in multiple lengths and diameters, and are intended to be used as stand-alone bone screws for internal bone fixation of fractures, fusions, osteotomies, non-unions, and malunions in adults and in both children (2-12 years) and adolescents (12-21 years) in which growth plates have fused or in which growth plates will not be crossed by the screw fixation. The Avanti Orthopaedics Cannulated screws are cannulated for use with guidewires for precise placement in bone.

AI/ML Overview

The provided text describes a 510(k) premarket notification for Avanti Orthopaedics 2.2mm, 2.7mm, 3.2mm, and 4.0mm Cannulated Screws. This document focuses on demonstrating substantial equivalence to predicate devices, primarily through non-clinical performance testing of the device hardware itself, rather than the performance of an AI/ML powered medical device.

Therefore, the requested information regarding "acceptance criteria and the study that proves the device meets the acceptance criteria" in the context of an AI/ML medical device (referring to aspects like sample size, ground truth, expert consensus, MRMC studies, etc.) is not present in the provided document.

The document entirely pertains to the physical characteristics and performance of orthopedic screws.

Here's what can be extracted about the non-clinical performance testing of these orthopedic screws:


Summary of Acceptance Criteria and Device Performance for Orthopedic Screws

The provided document describes the acceptance criteria and performance for physical orthopedic devices, specifically Avanti Orthopaedics 2.2mm, 2.7mm, 3.2mm, and 4.0mm Cannulated Screws. The testing is focused on the mechanical properties and safety of the screws, not on an AI/ML algorithm's performance.

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Defined by)Reported Device Performance
Predetermined acceptance criteria as defined in the FDA guidance "Orthopedic Non-Spinal Metallic Bone Screws and Washers -Performance Criteria for Safety and Performance Based Pathway".The device met all predetermined acceptance criteria as defined in the referenced FDA guidance.

2. Sample Size Used for the Test Set and Data Provenance:

  • The document states that "Testing was performed per ASTM F543-17."
  • Sample Size: Not explicitly stated in the document. ASTM F543-17 (Standard Specification and Test Method for Metallic Bone Screws) would specify the required number of samples for each mechanical test (e.g., torsion, bending, dynamic fatigue).
  • Data Provenance: Not applicable in the context of clinical data/images. This testing pertains to the physical device. The testing was non-clinical (laboratory testing).

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:

  • Not applicable. Ground truth in this context refers to the physical properties and performance of the screw under specific test conditions, as defined by engineering standards (ASTM F543-17) and FDA guidance. No human expert interpretation of data is involved in establishing "ground truth" for mechanical testing.

4. Adjudication Method for the Test Set:

  • Not applicable. This is mechanical testing against defined specifications, not a subjective assessment requiring adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:

  • No. This is a physical medical device (orthopedic screw), not an AI/ML software device. MRMC studies are used for evaluating diagnostic or treatment planning software performance with human readers.

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

  • Not applicable. This is a physical medical device.

7. The Type of Ground Truth Used:

  • Engineering Standards and Specifications: The "ground truth" for the device's performance is established by the specified mechanical properties and performance requirements outlined in ASTM F543-17 and the FDA guidance "Orthopedic Non-Spinal Metallic Bone Screws and Washers - Performance Criteria for Safety and Performance Based Pathway". This is objective, measurable data.

8. The Sample Size for the Training Set:

  • Not applicable. This is a physical device, not an AI/ML algorithm that requires training data.

9. How the Ground Truth for the Training Set was Established:

  • Not applicable.

In summary, the provided FDA document is a 510(k) submission for conventional orthopedic screws, not an AI/ML device. Therefore, the detailed questions about AI/ML device performance (like training sets, ground truth establishment by experts, MRMC studies, etc.) are outside the scope of this document.

Dear Linda Braddon:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

Comparison of Technological Characteristics: Avanti Orthopaedics 3.2mm and 4.0mm Cannulated Compression Screws

{8}------------------------------------------------

Technological Characteristics

There are no significant technological differences between the subject and predicate devices. The subject device uses the same material as the additional predicate and reference device and all devices are manufactured using subtractive techniques. Any differences in available sizes between the subject and predicate devices were addressed via the additional predicates (K180541, K162825).

Non-Clinical Performance Testing Summary

Testing was performed per ASTM F543-17 and the device met all predetermined acceptance criteria as defined in the FDA guidance "Orthopedic Non-Spinal Metallic Bone Screws and Washers -Performance Criteria for Safety and Performance Based Pathway".

Conclusions

Based on the similarities of the intended use/indications for use, technological and functional characteristic, and the results of the non-clinical performance testing, the subject device is substantially equivalent to the legally marketed predicate device.

§ 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.
